title: How to customize the animation for the display of a popovercontroller?
body: <p>I would like to customize the animation to display a uipopovercontroller so that it can slide in from right to left when it appears. I basically would like to simulate the menu you can see in Flipboard. Is there a way to customize the animation without having to write a popovercontroller? It seems that the default behavior has the slide in functionality but it is too fast to see it happening. I didn't find any property where i can set a transition style.</p>
  
  <p>Any help would be greatly appreciated!</p>
