Push notification issue with iOS 10

Asked 14/9, 2016 at 12:34 Answered 28/12, 2016 at 7:34

I've developed one application in that i've implemented push notification. Currently it's live on apple store. Upto iOS 9 push is working fine but after iOS 10 it is not working.

What is the issue with the code?

the one that makes push work on iOS9 obviously – Navvy 14/10, 2016 at 14:24

For iOS 10 using xCode 8 GM.

I have resolved my issue with following steps using xCode 8 GM for iOS 10:

1) In the targets, under Capabilities enable Push Notifications to add Push Notifications Entitlements.

2) Implement UserNotifications.framework into your app. Import UserNotifications.framework in your AppDelegate.

#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder   <UIApplicationDelegate,UNUserNotificationCenterDelegate>

@end

3) In didFinishLaunchingWithOptions method assign UIUserNotificationSettings and implement UNUserNotificationCenter delegate.

#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{

if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0")){
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
         if( !error ){
             [[UIApplication sharedApplication] registerForRemoteNotifications];
         }
     }];  
}

return YES;
}

4) Now finally implement this two delegate methods.

//============For iOS 10=============

-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{

    //Called when a notification is delivered to a foreground app. 

    NSLog(@"Userinfo %@",notification.request.content.userInfo);

    completionHandler(UNNotificationPresentationOptionAlert);
}

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{

   //Called to let your app know which action was selected by the user for a given notification.

   NSLog(@"Userinfo %@",response.notification.request.content.userInfo);

}

Please remain the code as it is you are using for iOS 9, Only add lines of code to support Push notification for iOS 10 using UserNotifications.framework.

I did the same but not able to receive notification when app was terminated – Inhalation 21/9, 2016 at 6:28

-willPresentNotification == called when app is foreground and push comes, it can be used to configure to show or not to show incomed push -didReceiveNotificationResponse == called when notification opened from notification centre – Croom 23/9, 2016 at 11:9

If you would only like to do bare minimum, you just have to call [UNUserNotificationCentre requestAuthorizationWithOptions]. Linking to UserNotification.framework and UNUserNotificationCenterDelegate are for implementing the new iOS 10 interactive push notifications. – Ocasio 10/10, 2016 at 13:38

In my case, I only needed to do step #1. None of the others, including [UNUserNotificationCentre requestAuthorizationWithOptions], was required and push continued to work as before. – Perspiration 12/10, 2016 at 23:29

Hi @Ashish, i have implement above framework and code, but ios 10 not receive the notification why i don't know please help me. – Pensive 3/11, 2016 at 7:18

i want to store pay load into core data, when application in background, i did this iOS 9 and previous but iOS 10 does not working with above delegates, its only call when user taps..any idea to save push notification while in app background – Harwood 4/11, 2016 at 4:52

have you found the apple documentation related to this? – Peeve 18/11, 2016 at 6:55

You don't need Step 4 (conform to UNUserNotificationCenterDelegate) if you don't set the delegate property on UNUserNotificationCenter. It will continue behaving like iOS 9 in that case and the UIApplicationDelegate methods will be called (application:didReceiveRemoteNotification: and so on). – Baldridge 22/11, 2016 at 16:41

Why don't you check granted? In case of (granted == NO) callback sends nil for the error. It means user is not registered. – Epidote 18/12, 2017 at 11:21

@AlexNapitupulu could you please tell which method will execute when the app is in background and receives a notificaation? – Tani 18/4, 2018 at 12:57

Everything was working fine before iOS 10, In my case only capabilities settings cause this issue.

It must be turned on for push notification.

I fixed it by clicking "Fix me" button in the Push notifications section. The issue was missing entitlement for push notification – Trappings 3/10, 2016 at 19:3

everybody loves an answer where all you have to do is click a button :D – Cutter 20/2, 2017 at 22:4

@Honey could you please tell me which method gets executed when the app is in background and receive user notification? – Tani 18/4, 2018 at 12:58

@Tani see this answer – Cutter 18/4, 2018 at 21:5

I had an issue with iOS 10 silent push notifications. In iOS9 and earlier, sending a push notification that had additional data fields but had an empty aps attribute in the data worked fine. But in iOS10 a push notification with an empty aps attribute does not hit the didReceiveRemoteNotification app delegate method at all, meaning that all my silent push notifications (notifications that we just use internally to trigger actions while the app is open) stopped working in iOS10.

I was able to fix this without pushing an update to my app by adding at least one attribute to the aps part of the push notification, in my case I just added badge: 0 and my silent push notifications started working again in iOS 10. I hope this helps someone else!

aps = { badge = 7; "content-available" = 1; priority = 5; }; – Hakenkreuz 6/10, 2016 at 6:35

I was having the exact same issue. It helped me @jakedunc, thank you for sharing this. – Whitmire 8/10, 2016 at 22:18

Same issue. It seems like iOS 10 is a bit more strict about what it allows through. – Seducer 20/10, 2016 at 13:46

Be aware that by using priority 5 may lead to pushes not showing up at all, as it can be seen in the documentation: "They are throttled, and in some cases are not delivered."! – Kin 15/12, 2016 at 11:15

@jakedunc. aps attribute is from server side or we can it. – Cage 23/12, 2016 at 13:27

The swift 3 version of @Ashish Shah code is:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

//notifications
        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 {
            // Fallback on earlier versions
        }

        return true
    }
    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

    }

Don't forget, when testing, you must use sandbox address for your notifications to work.

Ur answered 28/12, 2016 at 7:34 Comment(2)

Can you please explain this? – Purpure 22/2, 2017 at 12:36

In my case what happened was that when updating from ios 9 to 10, my application server was sending the notification to production server where i was in development phase, so changing it back to development sandbox address fixed the issue – Ur 22/2, 2017 at 12:49

On iOS, the application approaches the client for authorization to get push warnings by calling the registerUserNotificationSettings: strategy for UIApplication.

The application calls the registerForRemoteNotifications: technique for UIApplication (iOS) or the strategy registerForRemoteNotificationTypes: of NSApplication (OS X).

The application executes the application:didRegisterForRemoteNotificationsWithDeviceToken: technique for UIApplicationDelegate (iOS) or NSApplicationDelegate (OS X) to get the one of a kind gadget token produced by the push benefit.

The application executes the application:didFailToRegisterForRemoteNotificationsWithError: technique for UIApplicationDelegate (iOS) or NSApplicationDelegate (OS X) to get a blunder if the enrolment fizzled.
