title: show counter while application is in background
body: <p>I'm making an application that listening on a UDP socket all the time, even if the application is in the background. when a certain data arrived throw the socket, I want to show the user timer that count 10 seconds from 10 to 0.</p>
  
  <p>is it possible to show this counter while the application is in the background?</p>
  
  <p>can I show the user any message in the background (except <code>[[UIApplication sharedApplication] presentLocalNotificationNow:...]</code> that not good for me), like apple alarm clock?</p>
  
  <p><strong>note</strong></p>
  
  <ul>
  <li>I don't need the application to be approved for app store. I just need it to work at home.</li>
  <li>I already successfully keeping the communication in the background and I know that the application running</li>
  </ul>
