title: Tab bar item as button
body: <p>I have 5 tab bar items in my tab bar, 4 of which have segues to navigation controllers which lead to view controllers. I want to make the middle tab bar item act as a button, so that when I click on it, I have control over what happens.</p>
  
  <p>Currently, my middle tab bar item is also connected to a navigation controller, which is not right because now when I click the tab bar item, it opens a black navigation controller. How can I convert the middle tab bar item to act as a button, rather than going to a navigation controller? </p>
  
  <p>If I remove the navigation controller, it also removes the tab bar item from the tab bar.</p>
