application:didReceiveRemoteNotification:fetchCompletionHandler Not Called

Question

It appears the function application:didReceiveRemoteNotification:fetchCompletionHandler is not called when the app has been forcefully quit. It was my impressio

Answer 1

As documented by Apple, the new multitasking API (fetch and remote-notification) will work only when the app in the suspended/background/foreground state.

• In the background/foreground state, then application:didReceiveRemoteNotification:fetchCompletionHandler will get triggered.

• In the Suspended state, then -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions will get triggered.

• In the Not Running state (your case), application:didReceiveRemoteNotification:fetchCompletionHandler never gets triggered.

Please refer to the Apple documentation for more about app states.
