title: willRotateToInterfaceOrientation not being called from presented viewcontroller
body: <p>I have <strong>uiviewcontroller on ipad</strong> with this configuration:</p>
  
  <p><code>shouldAutorotate (true)
  supportedInterfaceOrientations (UIInterfaceOrientationMaskAll)</code>
  and inside <code>willRotateToInterfaceOrientation</code> i perform some trick to adjust my interface.</p>
  
  <p>From a child of this controller I show a QuickLookController with this -poor- code.</p>
  
  <pre><code>[[[[[UIApplication sharedApplication] delegate] window] rootViewController] presentViewController:previewController animated:YES completion:nil];
  </code></pre>
  
  <p>But if I rotate my ipad the method <code>willRotateToInterfaceOrientation</code> not being called, So I cannot do the trick to adjust the interface.</p>
  
  <p>Someone can explain me or given me some advices? thanks</p>
