title: Get Bounds after tap outside from a UIPopoverController
body: <p>Imagine a ViewController with 2 UITextFields. When you tap on TextField1, it appears a Popover.</p>
  
  <p>Now, if I tap out of the popover, it disappears (OK). However, I want this behaviour:</p>
  
  <ul>
  <li>If I click outside of the popover, and this tap is on TextField2, I want to dismiss the popover (OK), AND throw an event (for example, open other popover from TextField2).</li>
  </ul>
  
  <p>I've tried this solution: <a href="https://stackoverflow.com/questions/2623417/iphone-sdk-dismissing-modal-viewcontrollers-on-ipad-by-clicking-outside-of-it">Iphone SDK dismissing Modal ViewControllers on ipad by clicking outside of it</a></p>
  
  <p>But handleTapBehind method doesn't execute if popover is visible.</p>
  
  <p>Is it possible?</p>
  
  <p>Thanks!</p>
