title: How to expose standard back button in view controller navigation?
body: <p>I need users to be able to navigate a data hierarchy (master level, detail level) and to create new master and detail objects accordingly. Both master and detail use arrays for their model and <code>TableViews</code> for presentation</p>
  
  <p>The navigation flow for this uses 2 navigation and table controllers like below. The + of the master and detail <code>TableViews</code> create new objects, the forst<code>TableCell</code> navigates to the second <code>TableView</code> using a segue:</p>

  <p>While the screenshot shows "Done" right now even when removing that <code>ButtonItem</code> the slot remains empty. </p>
  
  <p>I would like to show the standard back button instead: "&lt; Middlewares" in this case. In the tests I've only been able to get the back button when navigating to a normal <code>ViewController</code>, but not to another <code>NavigationController</code>. Is it possible to have it between <code>Navigation Controllers</code>, too?</p>
