iOS Remote push notification doesn't wake up app

[nepoty]

We use remote push notification with content available key set to 1 which , from
apple documentation, it has to wake up the app, but it doesn't work properly, sometimes
the app doesn't wake up.
We use this mechanism to send device location to our server.
Why remote push notification doesn't wake up my app all the time ?

Have you actually hooked up

- (void)application:(UIApplication *)applicationdidReceiveRemoteNotification:(NSDictionary *)userInfofetchCompletionHandler:(void (^)(UIBackgroundFetchResultresult))handler {
NSLog(@"awaken in background");
}

You should receive the nslog in your debugger if your app is in the background

Sorry you mentioned 'sometimes' this is because pushnotifications are not guarenteed to be delivered, also this background mode is guarenteed to work at least once in 24 hours.
