title: iOS 8 popoverpresentationcontroller popoverlayoutmargin not working
body: <p>I am using the new <code>popOverPresentationController</code> to present <code>UIPopOverController</code> in iOS 8.
  I set the <code>popOverLayoutMargins</code> with a value like <em>{65.0, 10.0, 45.0, 10.0}</em>.
  But these do not reflect when I present the popOverController. This used to work perfectly on iOS 7.
  Is this broken on ios 8?</p>
