Perform an action after user dismiss the app on iOS

I want to perform an action, ten seconds after the app goes to background and in condition that the user didn't back to the app during that time.

For doing so, I am using this code:

 -(void)applicationDidEnterBackground:(UIApplication *)application{

      UIBackgroundTaskIdentifier __block bgTask = 0;
      UIApplication  *app = [UIApplication sharedApplication];
      bgTask = [app beginBackgroundTaskWithExpirationHandler:^{
           [app endBackgroundTask:bgTask];
           bgTask = UIBackgroundTaskInvalid;
      }];
      dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
          [self checkSession];
      });
 }

  -(void)checkSession{
      sleep(10);
      if([[UIApplication sharedApplication] applicationState] != UIApplicationStateActive)  {
          NSLog(@"Do action after 10 seconds");
      }
      else{
         NSLog(@"Do nothing after 10 seconds");
      }
  }

The problem is that if the user terminate the app while it in background (By swipe it and dismiss it) , but before 10 seconds passed, the action will not be performed, and i'll see this log:

    <AppDelegate: 0x15557890> ending background task 5

Any idea how to perform the action in this case?

Try to use - (void)applicationWillTerminate:(UIApplication *)application for the case that user kills the app before your action is performed
