title: Beginner: How to add top bar with buttons on UITableViewController
body: <p>I'm new to iOS development, I just have <code>UITableViewController</code> in a storyboard. I would like to add a top bar to it with some buttons, how to do that?</p>
  
  <p>Notice, I'm using UITabBar that is created by "Storyboard" and my ITableViewController is one item of the UITabBar.  </p>
