title: How to get frame coordinates of a UIView within a UIViewController?
body: <p>I simply want to get the frame coordinates of a UIView iVar contained within a UIViewController.  For example, if but0 is the iVar, and this fcn is called from the ViewController ViewDidLoad method:</p>
  
  <pre><code>CGFloat x = self.but0.frame.origin.x;
  </code></pre>
  
  <p>This always returns 0, no matter where the button is placed with Interface Builder.  What am i missing?</p>
