iOS - Notifications not showing up when app is in background

I can trigger notifications when the app is in the foreground (i.e. they appear in the dropdown notifications area) but they don’t seem to appear once the app is in the background.

// fetch notifications in the background and foreground
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)notification 
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {

[RCTPushNotificationManager didReceiveRemoteNotification:notification];
completionHandler(UIBackgroundFetchResultNewData);
NSLog(@"Notification Body %@", notification);

}

based on http://stackoverflow.com/a/36750318/2628278

In order for notifications to hit your app in the background you need to also define a fetchCompletionHandler, with a completion handler function like below. The aps:{content-available:1} payload should wake up you application and trigger this code in your AppDelegate, and in turn hit your JavaScript in RN.

@npomfret I stopped working on the project which used this library. Feel free to close it if you like.
