In application we have mechanism like native Reminder app in iOS with firing notifications when user enter or exit in some region.
But two devices behave differently (5 and 5s) in same time. All devices have enable notifications, and allow use locations.
Two devices have a some "travel" and in the route created 10 points. First device (5) when came to finish received only 6 notifications, (5s) don't receive any notification.
But my question is how I can know when my app is restart in background or continue working. Because, all log in app I redirect into a file, and after download container and analyze what happened in app in travel time.
I noticed app restart in same times when device is enter to region and my log marks fired in the file but notifications don't receive. This is happended when app try to get some information from web service in didFinishLaunchingWithOptions
And maybe this is problem. How to know distinguish restart app or continue working. Thx.
Are you checking UIApplicationLaunchOptionsLocationKey in didFinishLaunchingWithOptions similar to (sorry, Swift is what I have now):
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if launchOptions?[UIApplicationLaunchOptionsLocationKey] != nil {
// app was launched in response to incoming location event
}
}
Additionally, if you're not already doing this you may need to create notifications differently if app is in background:
// Show an alert if application is active
if UIApplication.sharedApplication().applicationState == .Active {
if let message = notefromRegionIdentifier(region.identifier) {
if let viewController = window?.rootViewController {
showSimpleAlertWithTitle(nil, message: message, viewController: viewController)
}
}
}
else {
// Otherwise present a local notification:
let notification = UILocalNotification()
notification.alertBody = notefromRegionIdentifier(region.identifier)
notification.soundName = "Default";
UIApplication.sharedApplication().presentLocalNotificationNow(notification)
}

I have an application that by design should be activated by the OS after a location event is delivered from the system even if the app has been terminated. Terminated can mean terminated by the system or by the user in the multitasking switcher. My app delegate code is below and the location delegate is an extension of the app delegate class. The first event that is generated by the system after the app is terminated is delivered to my app and processed properly, but I am not receiving any subsequent events. Is there some code I need to run after the event is received to reregister my application for future updates?
var window: UIWindow?
var locationManager: CLLocationManager!
var notificationCenter: UNUserNotificationCenter?
var today:String? //Today's date format: YYYY-MM-DD
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if launchOptions?[UIApplicationLaunchOptionsKey.location] != nil {
self.locationManager = CLLocationManager()
self.locationManager.delegate = self
self.locationManager.requestAlwaysAuthorization()
self.locationManager.startMonitoringVisits()
self.locationManager.allowsBackgroundLocationUpdates = true
sendTestNotification()
} else {
print("normal launch")
}
You say your app has been "terminated". This suggests that you kill your app intentionally as a way of testing. But if an app has been forcibly terminated, the system deliberately stops background location monitoring, so naturally you won't get any more visit monitoring events. It is as if you had called stopMonitoringVisits yourself.
app terminate is not allow by apple as i know.
exit(0)
you can use that code line to app terminate
I added push notification support to my iOS app using OneSignal some time before. The app is made in Xcode with Swift.
I want to send a test push notification only to my test device(s). I the documentation I found the following manual: How do I send a notification to a single user?
I managed to create the segment but I don't know where to put this peace of code: OneSignal.sendTag("is_test", "true")
Does anybody know where I have to put this piece of code to make it working as I described above?
I uploaded my code here: https://codeshare.io/DxcNn
Thanks,
David.
Update:
OneSignal now also supports to set a device as test device without doing something in the code. You can also download your own app from App Store and use it as test device. Just select you device from devices list one OneSignal and mark it as test device. You can find your device in the list by model, version and/or time added.
The sendTag method is from the device sdk. In your case iOS.
https://documentation.onesignal.com/docs/ios-native-sdk#section--sendtag-
You should do this anytime after initWithLaunchOptions in the app delegate. Updated code based on comments
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
let oneSignal = OneSignal(launchOptions: launchOptions, appId: "here_is_my_onesignal_app_id") { (message, additionalData, isActive) in
NSLog("OneSignal Notification opened:\nMessage: %#", message)
if additionalData != nil {
NSLog("additionalData: %#", additionalData)
// Check for and read any custom values you added to the notification
// This done with the "Additonal Data" section the dashbaord.
// OR setting the 'data' field on our REST API.
if let customKey = additionalData["customKey"] as! String? {
NSLog("customKey: %#", customKey)
}
}
}
OneSignal.defaultClient().sendTag("is_test", value: "true")
// Override point for customization after application launch.
return true
}
I am currently using OneSignal for notification service to my app.I really need a help with accessing notification additionaldata(payload data) from AppDelegate inside didFinishLunchingWithOption where OneSignal API can give me like this.
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var data : [NSObject : AnyObject]!
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
let oneSignal = OneSignal(launchOptions: launchOptions, appId: "48755d3d-abc0-4bac-8f71-095729bb3a65") { (message, additionalData, isActive) in
NSLog("OneSignal Notification opened:\nMessage: %#", message)
if additionalData != nil {
NSLog("additionalData: %#", additionalData)
self.data = additionalData
print(self.data)
}
}
oneSignal.enableInAppAlertNotification(true)
return true
}
}
but,I can only get the data if user click notification when appear or open it from notification center.So,if user neglect that notification without tapping when appear or without swiping or tapping from notification center,how do i get the additional data?
Actually,I want to store all payload data every time it comes into my device at realm database and fetch the data from my server according to that payload data.
You should use application(_:didReceiveRemoteNotification:fetchCompletionHandler:).
If you have enabled remote notifications background mode most of your notifications will be delivered even if the app is not running in the foreground. The only caveat being that the app must have been launched (since notifications are being pushed the user has done this) and it mustn't have been force-quit by the user.
More info in Apple's docs about that specific method.
Or in the "Local and Remote Notification Programming Guide's" notification handling chapter
You can extract all the payload in did finishLaunching by following method..
Let data = launchOptions.objectForKey(UIApplicationLaunchOptionsUIApplicationLaunchOptionsRemoteNotificationUIApplicationLaunchOptionsUIApplicationLaunchOptionsRemoteNotificationKey)
I am searching the way about how to handle push notification payload data as soon as the notification reaches to the client app without opening or tapping it.And I am still not getting the data unless the user tap or open it from notification center or banner or alert.The function didReceiveRemoteNotification only triggered when the user click the notification on the screen.So,how to get the notification payload data when the notification arrive to client app even the user ignore(without open or tap) it.
INFO : I heard that GCM(Google Cloud Messaging) can make notification handler if the client app user tapped the notification or not.It can catch the notification payload json data as soon as it reach the client app without even need user to tap or open it.Is that right?
I really need a hand to pick me up with getting notification payload data on ios without even need a user to open or tap it.
Update : The app is still running on device which mean it was active.I can get the payload data when i click my notification which was "{aps:} json i get it.But,I still cant get the data when i don't open the notification"
Here is my state
When the app was at foreground,I get the data.
1.I run the App,
2.Send Notification,
3.Get the notification with an alert,
4.I get the data(payload).
Work fine when app is active.
But,when the app reach to background
1.Run The app,
2.Close The App by pressing home button,
3.Send Notification,
4.Get the notification.
5.But,cant get the data until i click notification that I was receive at banner
or notification center.
But,when i click the notification at banner or notification it went to app and then i get the data.
Is there anyway that i can get the data if the app in background when the notification received.
Here is the code :
import UIKit
import RealmSwift
let realm = try! Realm()
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
var data : [NSObject : AnyObject]!
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
//one singnal is the push notification service that i use for push notification.
let oneSignal = OneSignal(launchOptions: launchOptions, appId: "__app_id__") { (message, additionalData, isActive) in
NSLog("OneSignal Notification opened:\nMessage: %#", message)
if additionalData != nil {
NSLog("additionalData: %#", additionalData)
}
}
oneSignal.enableInAppAlertNotification(true)
return true
}
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
print("User Info : \(userInfo)")
if let custom = userInfo["custom"] as? NSDictionary{
if let a = custom["a"] as? NSDictionary{
print("A : \(a)")
}
}
}
I came across the same problem. As mentioned in the previous comments, this post is quite helpful.
According to Apple,
When a remote notification arrives, the system displays the
notification to the user and launches the app in the background (if
needed) so that it can call this method. Launching your app in the
background gives you time to process the notification and download any
data associated with it, minimizing the amount of time that elapses
between the arrival of the notification and displaying that data to
the user.
The first thing you have to do is to allow your app to do something when in background. You do this by adding Required background mode in your info.plist, then add it App downloads content in response to push notifications. Your info.plist should look something like this:
Now this is done, your app should awake when it receive a notification. You can execute a small code inside didReceiveRemoteNotification. Such as this.
func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
//do some code here
UIBackgroundFetchResult.NewData
}
Note that you have to pay attention to the completionHandler:
As soon as you finish processing the notification, you must call the
block in the handler parameter or your app will be terminated. Your
app has up to 30 seconds of wall-clock time to process the
notification and call the specified completion handler block.
Let me know if everything is clear :)
I’m prompting my user to enable push notifications after the user logs in to my app. I know how to test if push notifications are enabled or disabled using:
isRegisteredForRemoteNotifications
and it works just fine. It returns YES for enabled and NO for not available but I want to be able to figure out how to check for Not Determined (the user wasn’t prompted to enable push notifications to begin with). Is there a way to test that?
Thanks in advance!
You create Not Determined state yourself.
func registerNotification() {
// 1.Call register API
// ...
// 2.Save a bool value to indicate you've called this method or not.
let appleSuggestedUserDefaultsKeyPrefix = "com.yourcompany.product-"
let key = appleSuggestedUserDefaultsKeyPrefix + "didCallRegisterNotificationAPI"
NSUserDefaults.standardUserDefaults().setBool(true, forKey: key)
}
And in didFinishLaunchingWithOptions method you need check if you have called registerNotification().
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
let didCallRegisterNotificationAPI = NSUserDefaults.standardUserDefaults().boolForKey(...)
if didCallRegisterNotificationAPI {
// If registered or user denied, call this method will NOT show the alert.
// Just the same as you did before.
registerNotification()
} else {
print("registerNotification() has not been called")
}
}
And finally you can call registerNotification() directly anywhere anytime as you need and the alert is under your control now.
isRegisteredForRemoteNotifications is a Bool. There is no undetermined status. You can verify this is the reference.
When the user first installs your app they must either allow or disallow push notifications. There is no other possible option.
However, maybe you're asking because you can delete the app, reinstall, and it won't ask you for permission. That's because the permission is remembered.
Resetting the Push Notifications Permissions Alert on iOS
The first time a push-enabled app registers for push notifications, iOS asks the user if they wish to receive notifications for that app. Once the user has responded to this alert it is not presented again unless the device is restored or the app has been uninstalled for at least a day.
If you want to simulate a first-time run of your app, you can leave the app uninstalled for a day. You can achieve the latter without actually waiting a day by following these steps:
Delete your app from the device.
Turn the device off completely and turn it back on.
Go to Settings > General > Date & Time and set the date ahead a day or more.
Turn the device off completely again and turn it back on.
Reference
Associated Question: When I delete my iOS application push notification state remains
EDIT:
You can only use isRegisteredForRemoteNotifications to check that they are simply not registered, whether that's due to declining or due to you never trying to register.
However, as long as you try to register in a valid way (valid certs and profiles etc) and the user declines, your app will call did register, but with nil UIUserNotificationSettings:
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
if notificationSettings.types == nil {
println("You didn't allow notifcations")
}
}
You can make use of UNNotificationSettings's authorizationStatus property.
private func checkNotificationsAuthorizationStatus() {
let notificationCenter = UNUserNotificationCenter.current()
notificationCenter.getNotificationSettings { notificationSettings in
switch notificationSettings.authorizationStatus {
case .authorized:
print("Authorized to schedule or receive notifications.")
case .denied:
print("Not authorized to schedule or receive notifications.")
case .notDetermined:
print("Not determined whether the app is allowed to schedule notifications.")
case .provisional: // Available from iOS 12.0
print("Provisionally authorized to post noninterruptive user notifications.")
#unknown default:
print("Error")
}
}
}
Use it in didFinishLaunchingWithOptions like:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.registerForRemoteNotifications()
self.checkNotificationsAuthorizationStatus()
return true
}
