title: UIPopoverController without arrows?
body: <p>I would like to know to make an UIPopoverController without arrows
  In fact I would like to simulate something like this:
  <img src="https://i.stack.imgur.com/gGEH0.png" alt="Screenshot of the set-passcode screen from the iPad&#39;s System Preferences"></p>
  
  <p>See that</p>
  
  <ul>
  <li><p>There is no arrows</p></li>
  <li><p>There is a title that is somehow inside of a expanded top border of the UIPopoverController and not inside of it like in the normal UIPopoverController.</p></li>
  </ul>
  
  <p>I assume this is not really an UIPopoverController object but I would appreciate advices on how can I make the same effect (using CoreGraphics? -> specially the translucent degrade effect of the 3D outstanding border) and/or links to some sources if anyone has done this before.</p>
  
  <p>Thanks in advance.</p>

  <p>EDIT: </p>
  
  <p>I am still looking for this stuff and realized that even in third party apps is being used 
  an example is: twitterrific for iPad as seen in this picture.
  Anyone please? Putting the title inside the popovercontroller is just ugly.
