title: IB vs Programmatical Creation of UIButtons
body: <p>Let's say I want to create a lot of custom buttons with the same UIImage named X.
  Programmatically, I would create only one UIImage and add this to all the buttons I created.
  I was wondering if I created these buttons in Interface Builder would IB create only 1 UIImage X or a new UIImage X for each button?
  Thanks</p>
