title: Turn a page like a Book with UIView?
body: <p>I am trying to switch between <code>UIViews</code> by making it look like you are turning a page in a book.</p>
  
  <p>The <code>UIViewAnimationTransitionCurlUp</code> is pretty close if I could get it to curl toward the Left or Right. Is this possible?</p>
  
  <p>I have tried to use the <code>CATRansition</code> but none of the animation types come close to a page turning.</p>
  
  <p>Any suggestions on how to create this page animation transition that would turn a page toward the left or right?</p>
