  <p>I am using UIDocumentInteractionController in xamarin.ios</p>
  
  <p>But i need to find being full screen event. I mean, when i tapped the screen, it goes to the fullscreen mode but it doesnt hide navigationbar as you see in the picture. So if i can find that event i can hide the navigation bar, but exit fullscreen, i should also find it.</p>
  
  <p>before i tried these but not working</p>
  
  <pre><code>    NavigationController.HidesBarsOnTap = true;
      NavigationController.HidesBarsOnSwipe = true;
  </code></pre>
