title: SubView not adjusting on device rotation
body: <p>I am adding a subview to my view. Everything works fine. My app supports autorotation.
  When i rotate my device, my parent views shouldautorotate/willanimate gets called but subviews shouldautorotate/willanimate is not getting called. Because of this i am not able to set the position of UI components of subview.</p>
  
  <pre><code>viewController = [[abcController alloc] initWithNibName:@"abcController" bundle:nil];
  [self.view addSubview:viewController.view];
  </code></pre>
  
  <p>Any pointer will be helpful.</p>
