title: Animating removeFromSuperview
body: <p>I'd like to animate the transition from a subview back to the super view. </p>
  
  <p>I display the subview using:</p>
  
  <pre><code>[UIView beginAnimations:@"curlup" context:nil];
  [UIView setAnimationDelegate:self];
  [UIView setAnimationDuration:.5];
  [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
  [self.view addSubview:self.mysubview.view];
  [UIView commitAnimations];
  </code></pre>
  
  <p>The above works fine.  It's going back to the super view that I don't get any animation:</p>
  
  <pre><code>[UIView beginAnimations:@"curldown" context:nil];
  [UIView setAnimationDelegate:self];
  [UIView setAnimationDuration:.5];
  [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
  [self.view removeFromSuperview];
  [UIView commitAnimations];
  </code></pre>
  
  <p>Is there something different I should be doing to get the subview to animate when removed?</p>
