onNotification not being called when app was killed on iOS

Bug

I am sending local notifications using react-native-background-fetch. This works good. When the user clicks on a notification I redirect him to a certain screen. This always works in Android. For iOS it is working when the app is in foreground or background. When the app was killed and the user clicks on a notification, the app launches but the onNotification handler is not being called. I call PushNotification.configure from index.js, so timing should not be the issue.

I followed the fix here to get onNotification to work in foreground and background.

Steps To Reproduce

1. Configure the onNotification handler in index.js
2. Send a push notification while the app is killed
3. Check if the onNotification handler was called when the notification is clicked

Describe what you expected to happen:

onNotification should be called when coming from Foreground/Background or when the app was killed

was this ever resolved? having this issue when I send a silent notification, the app wakes up from a kill state but doesn’t call onNotification. This works well in android

Hi Friends, i have found solution. Please check below methods.

Add this code in below file. AppDelegate.m

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { …

  if (launchOptions != nil) { NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; if (userInfo != nil) { [self performSelector:@selector(callNotification:) withObject: userInfo afterDelay:10]; } }

… }

create new file methods in same class…

-(void) callNotification: (NSDictionary*) userInfo { [RNCPushNotificationIOS didReceiveRemoteNotification:userInfo]; }

Modify below File from framework RNCPushNotificationIOS.m

• (void)handleRemoteNotificationReceived:(NSNotification *)notification { … remoteNotification[@“notificationData”] = notification.userInfo[@“notification”]; … }

Update above line on this methods.

Now Check, you will data on onNotification method…

Hope this work for you…
