title: UITabViewController Tab Identification
body: <p>I have a simple iPhone app (modified from the UITabBarController project template) where each tab is a different set of data using the same view controller (similar to the iPod app).</p>
  
  <p>So for example if each tab was a person's name and hitting it would display their friends. Then each tab would use the same view controller right?</p>
  
  <p>My question now is how do I identify programmatically what tab just got pressed (and in what function) so I know to load the appropriate data. I see viewDidLoad called each time but how do I know what tab?</p>
