Push notifications

[demosthese]

With FirebaseInstanceID 2.0.3 push notifications don't work, but with 2.0.0 they do.

Xcode 9 cant make it work also! tried messaging 2.0.0, 2.0.2 and 2.0.3

[morganchen12]

Can you both include more information on how you've set up Messaging?

[flash23]

This solved the problem

-(void)registerForPush
{
    UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge;
    [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:authOptions completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if(granted && !error )
        {
            dispatch_async(dispatch_get_main_queue(), ^{
                [[UIApplication sharedApplication] registerForRemoteNotifications];
                [UNUserNotificationCenter currentNotificationCenter].delegate = self;
                
                [[PushManager sharedInstance] registerNotificationCategories];
                
                if([FIRApp defaultApp] == nil)
                {
                    [FIRApp configure];
                }
                [FIRMessaging messaging].delegate = self;
                
                DDLogDebug( @"Push registration success." );
            });
        }
        else
        {
            DDLogDebug( @"Push registration FAILED" );
        }
    }];
} 

Before this blokc was outside

if([FIRApp defaultApp] == nil)
{
               [FIRApp configure];
 }
 [FIRMessaging messaging].delegate = self;

like this

-(void)registerForPush
{
    if([FIRApp defaultApp] == nil)
    {
        [FIRApp configure];
    }
    [FIRMessaging messaging].delegate = self;
    
    UNAuthorizationOptions authOptions = UNAuthorizationOptionAlert | UNAuthorizationOptionSound | UNAuthorizationOptionBadge;
    [[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:authOptions completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if(granted && !error )
        {
            dispatch_async(dispatch_get_main_queue(), ^{
                [[UIApplication sharedApplication] registerForRemoteNotifications];
                [UNUserNotificationCenter currentNotificationCenter].delegate = self;
                
                [[PushManager sharedInstance] registerNotificationCategories];
                
                DDLogDebug( @"Push registration success." );
            });
        }
        else
        {
            DDLogDebug( @"Push registration FAILED" );
        }
    }];
}

it worked with XCode 8 and lower versions. There is some thread thing going on maybe....

[rsattar]

There is a bug which has been fixed internally but hasn't been released yet, that is likely causing the issue.

For now, as a workaround you should always just call [[UIApplication sharedApplication] registerForRemoteNotifications]; as early as possible (this does not create a user permissions dialog, and should always give you an APNs token).

[flash23]

thx

[Aurazion]

Also fixed for me, thanks !

[berlininsomniac]

It's not fixing it for me. The messages don't get delivered if the app is in the background on iOS 11.

[Aurazion]

@berlininsomniac Here is my fix in Swift if it can help you :

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        
        // [START set_messaging_delegate]
        Messaging.messaging().delegate = self
        // [END set_messaging_delegate]
        
        // Register for remote notifications. This shows a permission dialog on first run, to
        // show the dialog at a more appropriate time move this registration accordingly.
        // [START register_for_notifications]
        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: {_, _ in })
        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }
        
        application.registerForRemoteNotifications()
        // [END register_for_notifications]
        
        FirebaseApp.configure()

        return true
    }

[rsattar]

@berlininsomniac Not receiving messages in the background usually indicates an issue with the app configuration for APNs (i.e. check if application:didRegisterForRemoteNotificationsWithDeviceToken: is being called in your app delegate), or perhaps you are making a non-APNs request to the FCM API (i.e. if you are not sending a notification payload, and not including content_available=1).

There is also a known issue in iOS 11.0 where silent notifications (content_available=1) are arriving on the device, but not actually being delivered to the app.

[Aurazion]

@rsattar It doesn't work anymore, without changing my code ... Waiting the fix release ....
Thanks

[PaulRBerg]

@Aurazion Confirming that [email protected] is fully operational when you add application.registerForRemoteNotifications() as the first line in didFinishLaunchingWithOptions.

Waiting for the final fix though, kinda ugly solution.

[rsattar]

FWIW, if you're locking temporarily to 2.0.0 you don't need to also call application.registerForRemoteNotifications() on app start.

[berlininsomniac]

I can confirm that downgrading FirebaseInstanceID to 2.0.0 reenables pushes on iOS 11.

[priyankamistry09]

How to downgrade the FirebaseInstanceID?
I am just adding
pod 'Firebase/Core', '4.0.1' pod 'Firebase/Messaging'
if I do
pod 'Firebase/Core', '4.0.1' pod 'Firebase/Messaging', '2.0.0' pod 'Firebase/InstanceID', '2.0.0'
Which doesn't allow me to install pod.
Any idea?

[PaulRBerg]

Try pod 'FirebaseInstanceID', '2.0.0'

[JussiSuojanen]

pod 'FirebaseInstanceID', '2.0.0', fixed the problem for me. Thanks for everyone in this feed. Saved my day :)

[Aurazion]

Same for me with pod 'FirebaseInstanceID', '2.0.0'
Thanks

[paulb777]

Indeed, it came back again.
