title: Correct way to Add the right navigation button with Interface Builder
body: <p>I have a single storyboard with the set of view controllers.
  How can I add the right buttons in the navigation bar not on the first view controller?
  What I want is displayed on the following screen:<a href="https://i.stack.imgur.com/08NzY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/08NzY.png" alt="story board example"></a></p>
  
  <p>In the first view controller NavigationItem is added by default (highlighted name "Nearest...") and can not be deleted in anyway.
  But all others view controllers do not have any navigation item by default.
  Is this OK if I add Navigation Item by drag it by myself (highlighted by yellow with name "Groups list") and setup buttons with Bar Button Item? </p>
