title: iOS 8 - UIPopoverPresentationController moving popover
body: <p>I am looking for an effective way to re-position a popover using the new uipopoverpresentationcontroller. I have succesfully presented the popover, and now I want to move it without dismissing and presenting again. I am having trouble using the function:</p>
  
  <pre><code>(void)popoverPresentationController:(UIPopoverPresentationController *)popoverPresentationController
        willRepositionPopoverToRect:(inout CGRect *)rect
                             inView:(inout UIView **)view
  </code></pre>
  
  <p>I know it's early in the game, but it anyone has an example of how to do this efficiently I would be grateful if you shared it with me. Thanks in advance. </p>
