I just created an application to notify the task in a specific time.And It's working perfectly on time.
If I click on the notification bar it opens the app and show a alert box.
But I have problem when i cleared the application from background. Notification is working but I can't able to see the alert box when the application is opens through notification.
Please help if any one know
try this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
NSDictionary *userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if(userInfo)
{
[self application:application didReceiveRemoteNotification:userInfo];
}
return YES;
}
- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
}
swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
if let lanuchOptions = launchOptions,
let userInfo = lanuchOptions[UIApplicationLaunchOptionsKey.remoteNotification] as? [AnyHashable: Any] {
self.application(application, didReceiveRemoteNotification: userInfo)
}
return true
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
}

I want to know what function should be called back or when I receive a notification while my app is suspended/killed. I am able to handle while my APP is in foreground/background however when the app is killed that's where I am not sure how and where to handle or parse my notification payload?
On open application from the notification, you will get the notification data in application:didFinishedLaunchingWithOptions method will called.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (launchOptions != nil)
{
// opened from a push notification when the app is closed
NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (userInfo != nil)
{
NSLog(#"userInfo->%#", [userInfo objectForKey:#"aps"]);
}
}
else
{
// opened app without a push notification.
}
}
Swift 5.1
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
if launchOptions != nil {
// opened from a push notification when the app is closed
let userInfo = launchOptions?[.remoteNotification] as? [AnyHashable : Any]
if userInfo != nil {
if let object = userInfo?["aps"] {
print("userInfo->\(object)")
}
}
} else {
// opened app without a push notification.
}
}
Here is my code for didReceiveRemoteNotification:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
print("notification recieved: \(userInfo)")
// Pass push notification payload to the shared model
let payload: NSDictionary = userInfo as NSDictionary
if let variable = payload["variable"] as? String {
NotificationManager.SharedInstance.handleVariableNotification(variable)
}
}
The code works and properly does what I want it to when I click on the notification from outside the app.
My issue is: if I get a notification while I'm currently in the app, it still runs the code from the notification and overrides anything the user is currently doing in the app
I only want the code to run if the user clicks on the notification, not automatically if I'm already in the app.
Thanks in advance!
Wrap your code in:
if (application.applicationState != .active){}
It will check if you are currently in the app, and fires the code only if the app was inactive or in the background.
Inside your didReceiveRemoteNotification delegate method:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
switch application.applicationState {
case .active:
print("Application is open, do not override")
case .inactive, .background:
// Pass push notification payload to the shared model
let payload: NSDictionary = userInfo as NSDictionary
if let variable = payload["variable"] as? String {
NotificationManager.SharedInstance.handleVariableNotification(variable)
}
default:
print("unrecognized application state")
}
}
Also if your application is being launched via user opening a remote notification sent by your application you will need to do this inside your app delegate didFinishLaunchingWithOptions method:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Check to see if launchOptions contains any data
if launchOptions != nil {
// Check to see if the data inside launchOptions is a remote notification
if let remoteNotification = launchOptions![UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary {
// Do something with the notification
}
}
return true
}
I want to differentiate if app becameActive in response to the RemoteNotification click. How to do that ?
you can check it like this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (notification) {
// it's launch from notification
}
else
{
// normal launch on app icon click
}
}
for swift plz use this
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if (launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? NSDictionary) != nil {
// it's launch from notification
}
else
{
// normal launch on app icon click
}
// Override point for customization after application launch.
return true
}
I have a push notification, and when app receives it, I call the following
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
if userInfo["t"] as! String == "rqst" {
print("type is help request")
if let token = NSUserDefaults.standardUserDefaults().objectForKey("authToken") {
authTokenOfHelper = token as! String
}
let storyBoard = UIStoryboard.init(name: "Main", bundle: nil)
let viewController = storyBoard.instantiateViewControllerWithIdentifier("helperMap")
let navController = UINavigationController.init(rootViewController: viewController)
self.window?.rootViewController = nil
self.window?.rootViewController = navController
self.window?.makeKeyAndVisible()
helpRequestReceived = true
}
}
this initialises storyboard.But if my app was killed by system and it is off and device recieves push, after tapping on push nothing is happened.
Seems that I have to use application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) if app is switched off
But how to access userInfo in didFinishLaunchingWithOptions ?
You can check this in didFinishLaunching using UIApplicationLaunchOptionsRemoteNotificationKey as launch options.
UIApplicationLaunchOptionsRemoteNotificationKey: Indicates that a
remote notification is available for the app to process. The value of
this key is an NSDictionary containing the payload of the remote
notification. > - alert: Either a string for the alert message or a
dictionary with two keys: body and show-view. > - badge: A number
indicating the quantity of data items to download from the provider.
This number is to be displayed on the app icon. The absence of a badge
property indicates that any number currently badging the icon should
be removed. > - sound: The name of a sound file in the app bundle to
play as an alert sound. If “default” is specified, the default sound
should be played.
You can call application:didReceiveRemoteNotification: in application:didFinishLaunchingWithOptions: manually.
Objective C
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// ...
if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
[self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
}
return YES;
}
Swift
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
if let remoteNotification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {
self.application(application, didReceiveRemoteNotification: launchOptions![UIApplicationLaunchOptionsRemoteNotificationKey]! as! [NSObject : AnyObject])
}
return true
}
This is in Objective C but the same thing is in Swift. Put this in didFinishLaunchingWithOptions:
NSDictionary *remoteNotif = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (remoteNotif) {
[self application:application didReceiveRemoteNotification:remoteNotif];
}
Swift:
if let remoteNotif = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {...}
How do I handle a push remote notification when the app is not running. Currently, when remote notification comes in, and my app is in foreground or background, my code is correctly handling the remote notification. But when the app is not running, and remote notification come in, I see a remote banner on top of screen, and when I tapped on it, my app get launch and go away. It doesn't seem to handle the remote notification correctly. Is this how iOS behave, or is there a way to handle it. Thanks. This is currently my code in AppDelegate.swift.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
...
println("..... application didFinishLaunchingWithOptions()")
if let remoteNotification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary {
// there is a notification...do stuff...
println("dinFInishLaunchingWithOption().. calling didREceiveRemoteNotification")
self.application(application, didReceiveRemoteNotification: remoteNotification as [NSObject : AnyObject])
}
return true
}
func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData)
{
println("didRegisterForRemoteNotificationsWithDeviceToken")
}
fun application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError)
{
println(error)
println(error.localizedDescription)
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject])
{
println("..... application didReceiveRemoteNotification()")
}
