title: UINavigationBar disappears when another view segue's to it?
body: <p>I have 5 view controllers in my app, the project starts with a <code>NavigationController</code>. Naturally when I could connect an action to "push" from view 1 to view 2, my view 2 would have a navigation bar and a back button. </p>
  
  <p>So my layout is like this: 1 ViewController has 4 round rect buttons with actions to "push" to the 4 other views. Since I have 5, the fifth one is actually an additional view that I have added, and in order to reach that view you must touch a round rect button that i have placed in the 4th view that will do a "flip horizontal" to the 5th view. </p>
  
  <p>Here is the problem, now my 5th view does not have a navigation bar, and when I add a round rect button on my 5th view to segue back to the 4th view, I now see that the navigation bar that once was is no longer there. </p>
  
  <p>I have tried to manually add a navigation bar to view 4 &amp; 5, I am able to do so successfully but I am unable to add "back" buttons to them by dragging them. Can someone help me fix this problem please?</p>
