title: EGOPhotoViewer and NavigationController
body: <p>I'm having a problem with EGOPhotoView library in my iOS app, and I hope someone of you can help me.</p>
  
  <p>My app uses a NavigationController, but does not display the NavigationBar, because the navigation is managed my some custom control. The problem is when I show an image gallery with the EGOPhotoView library, which shows a NavigationBar appearing on tap: when I pop the EGOPhotoViewController, the NavigationBar is still displayed, but I don't want.</p>
  
  <p>Can someone help me to fix this problem?</p>
  
  <p>Thanks</p>
