Get Apple's remote push notifications even after app terminates

问题


I am developing an iOS app which receives apple's remote push notifications at a particular time interval. The notifications are received successfully when app is active as well as when app is in background. But when app is terminated from app switcher/dock, notifications are not received until the app is started again.

I have tried following code to keep app alive in background. This same code is implemented in applicationWillTerminate: method, but it did not work.

__block UIBackgroundTaskIdentifier bgTask ;
    UIApplication  *app = [UIApplication sharedApplication];
    bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
        [app endBackgroundTask:bgTask];
        [app enabledRemoteNotificationTypes];
        bgTask = UIBackgroundTaskInvalid;
    }];

What is the perfect way of receiving notifications even after app is terminated?


回答1:


If you actively stop the app in the app switcher it stops receiving any push notifications.

This is an intended behaviour as stated by Apple engineers in the developer forums.
