title: remoteControlReceivedWithEvent not Called in appDelegate
body: <p>I'm having problem to control the iPhone controls with my avplayer.</p>
  
  <p>if I put the function</p>
  
  <pre><code>- (void)remoteControlReceivedWithEvent:(UIEvent *)event
  </code></pre>
  
  <p>in the view controller that responsible for playing the function called but only if I i'm going to background in the current view controller.</p>
  
  <p>if i'm going to background from other view controller the function never called.</p>
  
  <p>that's why i want to put it in the app delegate.</p>
  
  <p>I tried Becomefirstresponse and to put the function in every view controller but it did help.</p>
  
  <p>also I call </p>
  
  <pre><code>[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
  </code></pre>
  
  <p>in the </p>
  
  <pre><code>-(void)applicationWillResignActive:(UIApplication *)application
  </code></pre>
  
  <p>thanks</p>
