iOS：后台处理完成时显示通知

Question

我想向用户显示在应用程序结束后台处理时显示的通知。

这是我目前使用的代码：

UILocalNotification* localNotification = [[UILocalNotification alloc]init];
localNotification.alertBody = @"Your uploads are finished";
[[UIApplication sharedApplication]presentLocalNotificationNow:localNotification];

但这是行不通的，当我调用endBackgroundTask时，看不到该通知。 但是，我使用了断点，并执行了此代码。

   //identify the application state you through the Local notification
   UIApplicationState state = [[UIApplication sharedApplication] applicationState];

 if (state==UIApplicationStateInactive)
  {
                    //Show the notification as text voice
                    UILocalNotification *notification = [[UILocalNotification alloc]init];
                    [notification setAlertBody:"title"];
                    notification.soundName = UILocalNotificationDefaultSoundName;
                    notification.alertAction = @"View";
                    [[UIApplication sharedApplication] scheduleLocalNotification:notification];
                }
