title: iOS background service vibrate phone
body: <p>I have an app that runs in the background (location services). When the app is in the foreground it vibrates fine when I want it to, however, if its not in the foreground (in the multitasking view), the vibrate does not work anymore. Is this not allowed? Is there some way for my background app to give a vibrate alert? If not that what about a beeping sound?</p>
  
  <p>Right now I am just doing something like this:</p>
  
  <pre><code>    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
  </code></pre>
  
  <p>While importing:</p>
  
  <pre><code>#import &lt;AudioToolbox/AudioServices.h&gt;
  </code></pre>
