I am new to Firebase FCM Integration and i am facing some issues. When the app is installed for first time i don't receive Push Notification but if i open and close app for few times and then send push notification from Firebase i am receiving notification without any change in client or server code. Can anyone help me out on this?
I have attached my appdelegate code below
import UIKit
import Firebase
import UserNotifications
import FirebaseMessaging
import FirebaseInstanceID
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate,MessagingDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: { (granted, error) in
if error == nil{
UIApplication.shared.registerForRemoteNotifications()
}
})
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
}
application.registerForRemoteNotifications()
return true
}
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
print("Firebase registration token: \(fcmToken)")
}
func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
UIApplication.shared.registerForRemoteNotifications()
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// I have tried both method but none worked and i also tried MessagingAPNSTokenType.sandbox and prod
// Method 1: Messaging.messaging().apnsToken = deviceToken
// Method 2:
Messaging.messaging().setAPNSToken(deviceToken, type: MessagingAPNSTokenType.unknown)
}
}
Thanks in advance
I have the same issue as you have and there is a known issue where the FCM token is not always being associated with the APNs device token if UIApplication.shared.registerForRemoteNotifications() is not called early enough.
According to this GitHub thread this issue has already been fixed in the FirebaseInstanceID SDK, and should be coming out soon.
In the meantime, you can:
Lock your FirebaseInstanceID pod to 2.0.0 in your Podfile, or
Ensure you're calling UIApplication.shared.registerForRemoteNotifications() on app start, ideally before FirebaseApp.configure().
Update:
I just made some additional tests and I noticed that this is a bit random of when this will work. For some devices it worked immediately for some not. For some devices Single Token push worked and not User Segment. I managed to make it work so that you at least either get Single Token push or User Segment by adding the following:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if #available(iOS 10.0, *) {
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in
})
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
// For iOS 10 data message (sent via FCM)
Messaging.messaging().delegate = self
application.registerForRemoteNotifications()
print("::: registerForRemoteNotifications iOS 10")
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
print("::: registerUserNotificationSettings iOS 9")
}
FirebaseApp.configure()
Messaging.messaging().delegate = self
Messaging.messaging().shouldEstablishDirectChannel = true
if let refreshedToken = InstanceID.instanceID().token() {
print("::: InstanceID token: \(refreshedToken)")
}
NotificationCenter.default.addObserver(self, selector: #selector(tokenRefreshNotification), name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
Messaging.messaging().setAPNSToken(deviceToken, type: .prod)
if let refreshedToken = InstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
}
}
The thing is that it won´t work if you don´t access the didRegisterForRemoteNotificationsWithDeviceToken function.
Firebase FCM, it takes sometime to generate its first token. After getting this token you will start receiving push notification. Check these out. It will be clear for sure:

I do like below in Swift 2. But It's not working in Swift 3. How Can I provide this? If someone explain this It would be great.
didFinishLaunchingWithOptions
let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
application.registerForRemoteNotifications()
and
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
if notificationSettings.types != .None {
application.registerForRemoteNotifications()
}
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
print("Meesage ID \(userInfo["gcm_message_id"]!)")
print(userInfo)
}
I can do simple local notification but, I couldn't remote push notification from Firebase.
I tried
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Alert, .Badge, .Sound]) { (success, error:NSError?) in
if success {
print("Notification access true!")
application.registerForRemoteNotifications()
}
else {
print(error?.localizedDescription)
}
}
and
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
print("Meesage ID \(userInfo["gcm_message_id"]!)")
print(userInfo)
}
still doesn't work.
The AppDelegate method names have changed a little and UserNotifications framework has been introduced. You must use this framework for notifications in iOS 10 and above as the other methods are being deprecated.
import UserNotifications
...
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> ()) {
print("Message ID \(userInfo["gcm.message_id"]!)")
print(userInfo)
}
...
}
Registering for Push Notifications in Xcode 8/Swift 3.0?
It is very important to remember that there may be different devices that run different versions of the iOS, and they may have different notification capabilities. I understand that the previous answer does point in the right direction.
We need to import FirebaseInstanceID, if we are to receive instance, or event based notifications. Such notifications are like the ones that pop-up when someone retweets our post, or likes a post, or a message notification.
However, if someone is looking for the complete code that goes into the didFinishLaunchingWithOptions function in AppDelegate, here it is:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
FIRApp.configure()
if #available(iOS 10.0, *) {
let authOptions : UNAuthorizationOptions = [.Alert, .Badge, .Sound]
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions(
authOptions, completionHandler: {_,_ in })
} else {
// Fallback on earlier versions
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
}
application.registerForRemoteNotifications()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self,
selector: #selector(self.tokenRefreshNotification),
name: kFIRInstanceIDTokenRefreshNotification,
object: nil)
return true
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
// This is required if you are receiving a notification message while your app is in the background, which is the most common case!!
print("Message ID: \(userInfo["gcm.message_id"]!)")
print("%#", userInfo)
}
func tokenRefreshNotification(notification: NSNotification) {
if let refreshedToken = FIRInstanceID.instanceID().token() {
print("InstanceID token: \(refreshedToken)")
}
connectToFcm()
}
func connectToFcm() {
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil) {
print("Unable to connect with FCM. \(error)")
} else {
print("Connected to FCM.")
}
}
}
func applicationDidBecomeActive(application: UIApplication) {
connectToFcm()
}
func applicationDidEnterBackground(application: UIApplication) {
FIRMessaging.messaging().disconnect()
print("Disconnected from FCM.")
}
This is what works for me Xcode 8, Swift 3.
Inside didFinishLaunchingwithOptions func in AppDelegate.swift
if #available(iOS 10.0, *) {
let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {granted, error in
print(granted)
})
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
FIRApp.configure()
// [START set_messaging_delegate]
FIRMessaging.messaging().remoteMessageDelegate = self
// [END set_messaging_delegate]
And the Delegates required to receive notifications from firebase:
#available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {
// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
let userInfo = notification.request.content.userInfo
// Print message ID.
print("Message ID: \(userInfo["gcm.message_id"]!)")
// Print full message.
print("%#", userInfo)
let aps = userInfo["aps"] as! [String: Any]
let notificationMessage = aps["alert"] as! String // processed content from notificaton
}
}
extension AppDelegate : FIRMessagingDelegate {
// Receive data message on iOS 10 devices.
func applicationReceivedRemoteMessage(_ remoteMessage: FIRMessagingRemoteMessage) {
print("%#", remoteMessage.appData)
}
}
I'm trying to get my app working in Xcode 8.0, and am running into an error. I know this code worked fine in previous versions of swift, but I'm assuming the code for this is changed in the new version. Here's the code I'm trying to run:
let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.shared().registerForRemoteNotifications()
The error that I'm getting is "Argument labels '(forTypes:, categories:)' do not match any available overloads"
Is there a different command that I could try to get this working?
Import the UserNotifications framework and add the UNUserNotificationCenterDelegate in AppDelegate.swift
Request user permission
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()
return true
}
Getting device token
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
print(deviceTokenString)
}
In case of error
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("i am not available in simulator \(error)")
}
In case if you need to know the permissions granted
UNUserNotificationCenter.current().getNotificationSettings(){ (settings) in
switch settings.soundSetting{
case .enabled:
print("enabled sound setting")
case .disabled:
print("setting has been disabled")
case .notSupported:
print("something vital went wrong here")
}
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if #available(iOS 10, *) {
//Notifications get posted to the function (delegate): func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void)"
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
guard error == nil else {
//Display Error.. Handle Error.. etc..
return
}
if granted {
//Do stuff here..
//Register for RemoteNotifications. Your Remote Notifications can display alerts now :)
DispatchQueue.main.async {
application.registerForRemoteNotifications()
}
}
else {
//Handle user denying permissions..
}
}
//Register for remote notifications.. If permission above is NOT granted, all notifications are delivered silently to AppDelegate.
application.registerForRemoteNotifications()
}
else {
let settings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
}
return true
}
import UserNotifications
Next, go to the project editor for your target, and in the General tab, look for the Linked Frameworks and Libraries section.
Click + and select UserNotifications.framework:
// iOS 12 support
if #available(iOS 12, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound, .provisional, .providesAppNotificationSettings, .criticalAlert]){ (granted, error) in }
application.registerForRemoteNotifications()
}
// iOS 10 support
if #available(iOS 10, *) {
UNUserNotificationCenter.current().requestAuthorization(options:[.badge, .alert, .sound]){ (granted, error) in }
application.registerForRemoteNotifications()
}
// iOS 9 support
else if #available(iOS 9, *) {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
// iOS 8 support
else if #available(iOS 8, *) {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
// iOS 7 support
else {
application.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
}
Use Notification delegate methods
// Called when APNs has assigned the device a unique token
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
// Convert token to string
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
print("APNs device token: \(deviceTokenString)")
}
// Called when APNs failed to register the device for push notifications
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
// Print the error to console (you should alert the user that registration failed)
print("APNs registration failed: \(error)")
}
For receiving push notification
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
completionHandler(UIBackgroundFetchResult.noData)
}
Setting up push notifications is enabling the feature within Xcode 8
for your app. Simply go to the project editor for your target and then
click on the Capabilities tab. Look for Push Notifications and toggle
its value to ON.
Check below link for more Notification delegate methods
Handling Local and Remote Notifications UIApplicationDelegate - Handling Local and Remote Notifications
https://developer.apple.com/reference/uikit/uiapplicationdelegate
I had issues with the answers here in converting the deviceToken Data object to a string to send to my server with the current beta of Xcode 8. Especially the one that was using deviceToken.description as in 8.0b6 that would return "32 Bytes" which isn't very useful :)
This is what worked for me...
Create an extension on Data to implement a "hexString" method:
extension Data {
func hexString() -> String {
return self.reduce("") { string, byte in
string + String(format: "%02X", byte)
}
}
}
And then use that when you receive the callback from registering for remote notifications:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.hexString()
// Send to your server here...
}
In iOS10 instead of your code, you should request an authorization for notification with the following: (Don't forget to add the UserNotifications Framework)
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().requestAuthorization([.alert, .sound, .badge]) { (granted: Bool, error: NSError?) in
// Do something here
}
}
Also, the correct code for you is (use in the else of the previous condition, for example):
let setting = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
UIApplication.shared().registerUserNotificationSettings(setting)
UIApplication.shared().registerForRemoteNotifications()
Finally, make sure Push Notification is activated under target-> Capabilities -> Push notification. (set it on On)
Well this work for me.
First in AppDelegate
import UserNotifications
Then:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
registerForRemoteNotification()
return true
}
func registerForRemoteNotification() {
if #available(iOS 10.0, *) {
let center = UNUserNotificationCenter.current()
center.delegate = self
center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
if error == nil{
UIApplication.shared.registerForRemoteNotifications()
}
}
}
else {
UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
UIApplication.shared.registerForRemoteNotifications()
}
}
To get devicetoken:
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let deviceTokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
}
Heads up, you should be using the main thread for this action.
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
if granted {
DispatchQueue.main.async(execute: {
UIApplication.shared.registerForRemoteNotifications()
})
}
}
First, listen to user notification status, i.e., registerForRemoteNotifications() to get APNs device token;
Second, request authorization. When being authorized by the user, deviceToken will be sent to the listener, the AppDelegate;
Third, report the device token to your server.
extension AppDelegate {
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// 1. listen（监听） to deviceToken
UIApplication.shared.registerForRemoteNotifications()
// 2. request device token
requestAuthorization()
}
func requestAuthorization() {
if #available(iOS 10, *) {
let uc = UNUserNotificationCenter.current()
uc.delegate = UIApplication.shared.delegate as? AppDelegate
uc.requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if let error = error { // 无论是拒绝推送，还是不提供 aps-certificate，此 error 始终为 nil
print("UNUserNotificationCenter 注册通知失败, \(error)")
}
DispatchQueue.main.async {
onAuthorization(granted: granted)
}
}
} else {
let app = UIApplication.shared
app.registerUserNotificationSettings(UIUserNotificationSettings(types: [.badge, .sound, .alert], categories: nil))
}
}
// 在 app.registerUserNotificationSettings() 之后收到用户接受或拒绝及默拒后，此委托方法被调用
func application(_ app: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {
// 已申请推送权限，所作的检测才有效
// a 征询推送许可时，用户把app切到后台，就等价于默拒了推送
// b 在系统设置里打开推送，但关掉所有形式的提醒，等价于拒绝推送，得不token，也收不推送
// c 关掉badge, alert和sound 时，notificationSettings.types.rawValue 等于 0 和 app.isRegisteredForRemoteNotifications 成立，但能得到token，也能收到推送（锁屏和通知中心也能看到推送），这说明types涵盖并不全面
// 对于模拟器来说，由于不能接收推送，所以 isRegisteredForRemoteNotifications 始终为 false
onAuthorization(granted: app.isRegisteredForRemoteNotifications)
}
static func onAuthorization(granted: Bool) {
guard granted else { return }
// do something
}
}
extension AppDelegate {
func application(_ app: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
//
}
// 模拟器得不到 token，没配置 aps-certificate 的项目也得不到 token，网络原因也可能导致得不到 token
func application(_ app: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
//
}
}
The answer from ast1 is very simple and useful. It works for me, thank you so much.
I just want to poin it out here, so people who need this answer can find it easily. So, here is my code from registering local and remote (push) notification.
//1. In Appdelegate: didFinishLaunchingWithOptions add these line of codes
let mynotif = UNUserNotificationCenter.current()

center.delegate = self
center.requestAuthorization(options: []) { _, _ in
application.registerForRemoteNotifications()

I include google firebase in my app - create google account, create google app, upload APNS certifications (.pem and in work in another service), and send push notifications from console, and my app not receive it. In Firebase console i see status complete but Approximate number of devices is "-"
Of course I updated provisions profiles and APNS cert

The first thing I see is there's no call to connect to FIRMessaging. Try adding this to your AppDelegate:
func applicationDidBecomeActive(application: UIApplication) {
FIRMessaging.messaging().connectWithCompletion { error in
print(error)
}
}
Use the following code.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
if #available(iOS 10.0, *)
{
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted
{
//self.registerCategory()
}
}
// For iOS 10 data message (sent via FCM)
FIRMessaging.messaging().remoteMessageDelegate = self
}
else
{
let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert,.Badge,.Sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
//Configuring Firebase
FIRApp.configure()
// Add observer for InstanceID token refresh callback.
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.tokenRefreshNotification), name: kFIRInstanceIDTokenRefreshNotification, object: nil)
return true
}
//Receive Remote Notification on Background
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void)
{
FIRMessaging.messaging().appDidReceiveMessage(userInfo)
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
{
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Sandbox)
FIRInstanceID.instanceID().setAPNSToken(deviceToken, type: FIRInstanceIDAPNSTokenType.Prod)
}
func tokenRefreshNotification(notification: NSNotification)
{
if let refreshedToken = FIRInstanceID.instanceID().token()
{
print("InstanceID token: \(refreshedToken)")
}
// Connect to FCM since connection may have failed when attempted before having a token.
connectToFcm()
}
func connectToFcm()
{
FIRMessaging.messaging().connectWithCompletion { (error) in
if (error != nil)
{
print("Unable to connect with FCM. \(error)")
}
else
{
print("Connected to FCM.")
}
}
}
func applicationDidBecomeActive(application: UIApplication)
{
connectToFcm()
}
You might be using Data or aps key in PUSH JSON which is used to send notifications to devices. It should work properly but in rare cases, it not works, even it'll give you success in fcm/send api but notification will not reach particular devices. This problem usually occurs in iOS devices.
A solution which worked for me is add notification key instead of Data.
{
"to" : "device token",
"notification":{
"body": "test",
"title": "test"
}
}
If you are sending from Backend OR you don't have access of Firebase console. Then you can test and send notification via POSTMAN also. But you must have SERVER KEY, which can be got from Firebase console under Cloud Messaging settings.
API: https://fcm.googleapis.com/fcm/send
Method: POST
Headers:
"Content-Type"=application/json
"Authorization"="key=YOUR SERVER KEY" //You must add key= above the server key.
{
"to" : "your device token",
"notification":{
"body": "test",
"title": "test"
}
}
ANOTHER DETAILED AND FULL PAYLOAD IF YOU NEED TO SEE WHAT WE CAN SEND IN FIREBASE NOTIFICATION:
{
"to":"device token",
"notification":{
"data":{
"avatar":"",
"body":"",
"key_notification":"0",
"type_notification":"1",
"deviceToken":"device token",
"badge":1,
"message":"your text"
},
"text":"your text",
"sound":"sound.caf",
"badge":21
},
"priority":"high"
}
I am trying to set up a push notification system for my application. I have a server and a developer license to set up the push notification service.
I am currently running my app in Swift. I would like to be able to send the notifications remotely from my server. How can I do this?
Swift 2:
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
While the answer is given well to handle push notification, still I believe to share integrated complete case at once to ease:
To Register Application for APNS, (Include the following code in didFinishLaunchingWithOptions method inside AppDelegate.swift)
IOS 9
var settings : UIUserNotificationSettings = UIUserNotificationSettings(forTypes:UIUserNotificationType.Alert|UIUserNotificationType.Sound, categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
After IOS 10
Introduced UserNotifications framework:
Import the UserNotifications framework and add the UNUserNotificationCenterDelegate in AppDelegate.swift
To Register Application for APNS
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// If granted comes true you can enabled features based on authorization.
guard granted else { return }
application.registerForRemoteNotifications()
}
This will call following delegate method
func application(application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
//send this device token to server
}
//Called if unable to register for APNS.
func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
println(error)
}
On Receiving notification following delegate will call:
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
println("Recived: \(userInfo)")
//Parsing userinfo:
var temp : NSDictionary = userInfo
if let info = userInfo["aps"] as? Dictionary<String, AnyObject>
{
var alertMsg = info["alert"] as! String
var alert: UIAlertView!
alert = UIAlertView(title: "", message: alertMsg, delegate: nil, cancelButtonTitle: "OK")
alert.show()
}
}
To be identify the permission given we can use:
UNUserNotificationCenter.current().getNotificationSettings(){ (setttings) in
switch setttings.soundSetting{
case .enabled:
print("enabled sound")
case .disabled:
print("not allowed notifications")
case .notSupported:
print("something went wrong here")
}
}
So the checklist of APNS:
Create AppId allowed with Push Notification
Create SSL certificate with valid certificate and app id
Create Provisioning profile with same certificate and make sure to add device in case of sandboxing(development provisioning)
Note: That will be good if Create Provisioning profile after SSL Certificate.
With Code:
Register app for push notification
Handle didRegisterForRemoteNotificationsWithDeviceToken method
Set targets> Capability> background modes> Remote Notification
Handle didReceiveRemoteNotification
To register to receive push notifications via Apple Push Service you have to call a registerForRemoteNotifications() method of UIApplication.
If registration succeeds, the app calls your app delegate object’s application:didRegisterForRemoteNotificationsWithDeviceToken: method and passes it a device token.
You should pass this token along to the server you use to generate push notifications for the device. If registration fails, the app calls its app delegate’s application:didFailToRegisterForRemoteNotificationsWithError: method instead.
Have a look into Local and Push Notification Programming Guide.
registerForRemoteNotification() has been removed from ios8.
So you should use UIUserNotification
CODE EXAMPLE:
var type = UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound;
var setting = UIUserNotificationSettings(forTypes: type, categories: nil);
UIApplication.sharedApplication().registerUserNotificationSettings(setting);
UIApplication.sharedApplication().registerForRemoteNotifications();
Hope this will help you.
To support ios 8 and before, use this:
// Register for Push Notitications, if running iOS 8
if application.respondsToSelector("registerUserNotificationSettings:") {
let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
} else {
// Register for Push Notifications before iOS 8
application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
}
Swift 4
I think this is the correct way for setup in iOS 8 and above.
Turn on Push Notifications in the Capabilities tab
Import UserNotifications
import UserNotifications
Modify didFinishLaunchingWithOptions
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if let notification = launchOptions?[.remoteNotification] as? [String: AnyObject] {
// If your app wasn’t running and the user launches it by tapping the push notification, the push notification is passed to your app in the launchOptions
let aps = notification["aps"] as! [String: AnyObject]
UIApplication.shared.applicationIconBadgeNumber = 0
}
registerForPushNotifications()
return true
}
It’s extremely important to call registerUserNotificationSettings(_:) every time the app launches. This is because the user can, at any time, go into the Settings app and change the notification permissions. application(_:didRegisterUserNotificationSettings:) will always provide you with what permissions the user currently has allowed for your app.
Copy paste this AppDelegate extension
// Push Notificaion
extension AppDelegate {
func registerForPushNotifications() {
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
[weak self] (granted, error) in
print("Permission granted: \(granted)")
guard granted else {
print("Please enable \"Notifications\" from App Settings.")
self?.showPermissionAlert()
return
}
self?.getNotificationSettings()
}
} else {
let settings = UIUserNotificationSettings(types: [.alert, .sound, .badge], categories: nil)
UIApplication.shared.registerUserNotificationSettings(settings)
UIApplication.shared.registerForRemoteNotifications()
}
}
#available(iOS 10.0, *)
func getNotificationSettings() {
UNUserNotificationCenter.current().getNotificationSettings { (settings) in
print("Notification settings: \(settings)")
guard settings.authorizationStatus == .authorized else { return }
DispatchQueue.main.async {
UIApplication.shared.registerForRemoteNotifications()
}
}
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { data -> String in
return String(format: "%02.2hhx", data)
}
let token = tokenParts.joined()
print("Device Token: \(token)")
//UserDefaults.standard.set(token, forKey: DEVICE_TOKEN)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("Failed to register: \(error)")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
// If your app was running and in the foreground
// Or
// If your app was running or suspended in the background and the user brings it to the foreground by tapping the push notification
print("didReceiveRemoteNotification /(userInfo)")
guard let dict = userInfo["aps"] as? [String: Any], let msg = dict ["alert"] as? String else {
print("Notification Parsing Error")
return
}
}
func showPermissionAlert() {
let alert = UIAlertController(title: "WARNING", message: "Please enable access to Notifications in the Settings app.", preferredStyle: .alert)
let settingsAction = UIAlertAction(title: "Settings", style: .default) {[weak self] (alertAction) in
self?.gotoAppSettings()
}
let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: nil)
alert.addAction(settingsAction)
alert.addAction(cancelAction)
DispatchQueue.main.async {
self.window?.rootViewController?.present(alert, animated: true, completion: nil)
}
}
private func gotoAppSettings() {
guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
return
}
if UIApplication.shared.canOpenURL(settingsUrl) {
UIApplication.shared.openURL(settingsUrl)
}
}
}
Check out: Push Notifications Tutorial: Getting Started
Thanks for the earlier answers. Xcode has made some changes and here's the SWIFT 2 code that passes XCode 7 code check and supports both iOS 7 and above:
if #available(iOS 8.0, *) {
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
UIApplication.sharedApplication().registerForRemoteNotifications()
} else {
let settings = UIRemoteNotificationType.Alert.union(UIRemoteNotificationType.Badge).union(UIRemoteNotificationType.Sound)
UIApplication.sharedApplication().registerForRemoteNotificationTypes(settings)
}
Swift 4
Import the UserNotifications framework and add the UNUserNotificationCenterDelegate in AppDelegate
import UserNotifications
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate
To Register Application for APNS, (Include the following code in didFinishLaunchingWithOptions method inside AppDelegate.swift)
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()
This will call following delegate method
func application(_ application: UIApplication,didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
//send this device token to server
}
//Called if unable to register for APNS.
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print(error)
}
On Receiving notification following delegate will call:
private func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
print("Recived: \(userInfo)")
//Parsing userinfo:
}
Swift 3:
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:[.badge, .alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
UIApplication.shared.registerForRemoteNotifications()
Make sure to import UserNotifications at the top of your view controller.
import UserNotifications
You can send notification using the following code snippet:
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
if(UIApplication.sharedApplication().currentUserNotificationSettings() == settings ){
//OK
}else{
//KO
}
I use this code snip in AppDelegate.swift:
let pushType = UIUserNotificationType.alert.union(.badge).union(.sound)
let pushSettings = UIUserNotificationSettings(types: pushType
, categories: nil)
application.registerUserNotificationSettings(pushSettings)
application.registerForRemoteNotifications()
100% Working... You Can read onesignal document and setup properly https://documentation.onesignal.com/docs/ios-sdk-setup
OneSignal below code import in AppDelegate
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
OneSignal.setLogLevel(.LL_VERBOSE, visualLevel: .LL_NONE)
// OneSignal initialization
let onesignalInitSettings = [kOSSettingsKeyAutoPrompt: false, kOSSettingsKeyInAppLaunchURL: false]
OneSignal.initWithLaunchOptions(launchOptions,
appId: "YOUR_ONE_SIGNAL_ID",
handleNotificationAction: nil,
settings: onesignalInitSettings)
OneSignal.inFocusDisplayType = OSNotificationDisplayType.inAppAlert;
// promptForPushNotifications will show the native iOS notification permission prompt.
// We recommend removing the following code and instead using an In-App Message to prompt for notification permission (See step 8)
OneSignal.promptForPushNotifications(userResponse: { accepted in
print("User accepted notifications: \(accepted)")
})
return true
}
