title: iOS - local notification - custom vibration or vibrate for longer duration
body: <p>I am trying to build an iPhone app that works like an alarm, I am using UILocalNotification</p>
  
  <p><strong>Problem</strong></p>
  
  <ul>
  <li>I would like the phone to vibrate for a longer duration. However currently it vibrates only once.</li>
  </ul>
  
  <p><strong>Alternative Approaches</strong></p>
  
  <ol>
  <li><p>Is it possible to use custom vibration patters ?(http://www.pcworld.com/article/242238/how_to_use_custom_vibrations_in_ios_5.html)</p></li>
  <li><p>Is it possible to execute a method, when the push notification is fired ? (but the app might not even be running, and yet it needs to work)</p></li>
  <li><p>Is NSTimer an option ? (but the app might not even be running, and yet it needs to work)</p></li>
  <li><p>Is there any other alternate ?</p></li>
  </ol>
