title: set up an action with a tab bar item - iphone
body: <p>I don't no if this is possible, but this there a way to treat a tab bar item click like a regular button click(action)? Here's the reason: I have a tab bar in my application, and for most of the tab bar items, I don't change the screen upon a touch, but I do change the data displayed in the view. It seems that it would be going a bit overboard to use a TabBarAppDelegate for this...is there a better way?</p>
  
  <p>Thanks</p>
