title: Cannot add right bar button in navigation bar in storyboards iOS8
body: <p>As the title suggests, I would like to know if it is possible to avoid adding right bar button in the navigation bar through code.</p>
  
  <p>I've done the usual process with a view controller embedded in a navigation controller and trying to drop the bar button item inside the navigation bar of the view controller, but it no longer works for some reasons.</p>
  
  <p>So is it possible to be done in the storyboard somehow in iOS 8?</p>
  
  <p>Xcode ver. 6.2 Stable</p>
