title: How to handle orientation change for subviews
body: <p>I have two UIViewControllers, UIViewControllerParent and UIViewControllerChild. Inside UIViewControllerParent I instantiate a child controller and add its view as a subview:</p>
  
  <pre><code>UIViewControllerChild *child = [[UIViewControllerChild alloc] init];
  [self.view addSubView:child.view];
  </code></pre>
  
  <p>Now when the orientation changes, only the parent viewcontrollers shouldAutorotateToInterfaceOrientation method gets called and only the parents orientation changes. Is it the correct behavior that the childs shouldAutorotateToInterfaceOrientation method does not get called and its view not to rotate?</p>
  
  <p>If so, what is the best practice method for getting the child view to rotate? There should be a way to ge the child controller to layout automatically, I just dont know how.</p>
  
  <p>Any advice?</p>
