title: Play local notification default sound when displaying UIAlertView?
body: <p>I'm writing a reminders app for iPhone that displays reminders using local notifications.</p>
  
  <p>If a reminder goes off while the application is running, the local notification isn't displayed. Instead, the <code>didReceiveLocalNotification</code> method is called in my app delegate, and I mimic the local notification dialog by displaying a <code>UIAlertView</code> with the reminder text.</p>
  
  <p>When local notifications are displayed outside of the app, the device vibrates and the sound specified by <a href="https://developer.apple.com/library/ios/documentation/iPhone/Reference/UILocalNotification_Class/Reference/Reference.html#//apple_ref/doc/uid/TP40009565-CH1-SW16" rel="noreferrer"><code>UILocalNotificationDefaultSoundName</code></a> is played. Again, I'd like to mimic this in the app when displaying the <code>UIAlertView</code>.</p>
  
  <p>I can vibrate the device by calling <code>AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)</code>, but I can't figure out how to play the local notification default sound. There's no equivalent SystemSoundID constant, and I'm not sure what the path would be.</p>
  
  <p><strong>tl;dr</strong> I'd like to play the local notification default sound when displaying a UIAlertView. Any ideas?</p>
