title: UITabBar(Controller) - Get index of tapped?
body: <p>I've got a tab bar application and I need to know when and what button a user taps on the tab bar as to display the appropriate notifications and such.</p>
  
  <p>In short: <strong>How would I go about detecting the index of a tapped UITabBarItem on a UITabBar?</strong></p>
  
  <p>Thanks in advance!</p>
