title: Slide gesture with custom back button freezes the root view controller
body: <p>I have custom back buttons all over my app and it looks like navigation controller does not like it. </p>
  
  <p>So, I want the iOS7 swipe-to-go-back gesture to work along with my custom back buttons. Searched and tried different ways but none seems to be promising. The closest I could get is with <a href="http://keighl.com/post/ios7-interactive-pop-gesture-custom-back-button/" rel="nofollow">http://keighl.com/post/ios7-interactive-pop-gesture-custom-back-button/</a>.
  However, Now when I keep pushing and popping the navigation stack, after sometime the rootViewController in the stack stops responding to any touch.</p>
  
  <p>Any suggestions?</p>
