title: UIPopoverController not sizing correctly in iOS 8
body: <p>Prior to iOS 8 my app using UIPopoverController was working fine. I had it anchored and opening up at a size of 400 x 215. However now when i run my app on iPad using iOS 8 my popover window is not sized properly.  Its almost popping up at the full height and width off my anchor. Since iOS is so new i can't seem to find an adjustment for this. Below is my code:</p>
  
  <pre><code>UIView *anchor = self.personAnchor;
          UIViewController *viewControllerForPopover =
          [self.storyboard instantiateViewControllerWithIdentifier:@"choosePersonViewController"];
  
  
          popover = [[UIPopoverController alloc]
                     initWithContentViewController:viewControllerForPopover];
          popover.popoverContentSize = CGSizeMake(400, 215);
          popover.delegate = self;
          [popover presentPopoverFromRect:anchor.frame
                                   inView:anchor.superview
                 permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
  </code></pre>
