title: How to set the boundaries for UIPopover with a CGRect?
body: <p>I am displaying a popover to be presented in a view but leaving some space at the top.</p>
  
  <p>I am using <code>presentPopoverFromrect:inView:permittedArrowDirections:</code> but apart from passing the view I also want to restrict the popover within the view within a rectangle.</p>
  
  <p>which means , the popover should not go outside this rect in the view and also adjust arrows accordingly.
  Is there a way that this can be made possible ?</p>
