title: iOS curl up animation to remove uiimageview
body: <p>i'm looking to remove an image from my app with a curl up animation. I've got </p>
  
  <pre><code>[UIView transitionWithView:sender.view.superview duration:1.5
  options:UIViewAnimationOptionTransitionCurlUp                           
  animations:^ { [sender.view removeFromSuperview]; }
  completion:nil];
  </code></pre>
  
  <p>but this curls the entire page away and looks as though there's a separate page beneath without the image on it.</p>
  
  <p>Instead of a 'transition' to a new page is it possible to curl the image off the page without affecting the rest of the page? Do I need to wrap the imageview in a 'container view' and change transition with view to that?</p>
