title: IOS MWPhotobrowser issue
body: <p>I am using MWPhotobrowser library as a photo viewer in my app. There is an option one can set e.g..</p>
  
  <pre><code>Mbrowser.wantsFullScreenLayout=YES;
  </code></pre>
  
  <p>This shows the photos in fullscreen mode. All works good.</p>
  
  <p>But when i use PKRevalController library in my app </p>
  
  <pre><code>https://github.com/pkluz/PKRevealController
  </code></pre>
  
  <p>It makes my photobrowser leave a space equal to height of status bar over the navigation controller. It happens when the navigation controller over the photo viewer disappears.</p>
  
  <p>When i disable the wantsFullScreenLayout then it gets ok but always shows the status bar.</p>
  
  <p>I dont know what is causing it. Any help will be much appreciated. Please refer to screen shot..!</p>
