title: Show alert on screen when app is in background
body: <p>I want to show multiple alerts after some time interval when the app is in background.</p>
  
  <p>Currently I am using local notification to show the alert but I cannot detect action when user presses the cancel button of local notification.</p>
  
  <pre><code> UILocalNotification *localNotif = [[UILocalNotification alloc] init];
  
              if (localNotif == nil)
                  return;
              localNotif.fireDate = [NSDate date];
              localNotif.timeZone = [NSTimeZone defaultTimeZone];
  
                      // Notification details
                      localNotif.alertBody = @"This is local notification message.";
                      // Set the action button
                      localNotif.alertAction = @"View";
                      localNotif.alertAction = @"Yes";
  
              localNotif.soundName = UILocalNotificationDefaultSoundName;
  
              [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
              [localNotif release];
  </code></pre>
  
  <p>Is there any other way I can show alert on screen when app is in background ?</p>
