title: How to add a Tab Bar to an existing view controller, without XIB
body: <p>I'm <strong>trying to avoid using Interface Builder</strong> as much as possible.</p>
  
  <p>At the moment I have the view controller created via code and change views via code as well.</p>
  
  <p>I now need one of the steps to <strong>send the app into</strong> a new view with <strong>a tab bar</strong>, that will allow me to change views as well.</p>
  
  <p>Ideally, what I'd do is tell the current view controller to add a Tab Bar to the bottom, but I'm not sure if that's doable, so I might have to swap the UIViewController with a UITabBarController?</p>
  
  <p>Any help will be appreciated.</p>
  
  <p>Cheers,
  Andre</p>
