title: UIButton label text is being clipped
body: <p>I have a UIButton built in Interface Builder that has a default label. In Xcode, I'm changing the label text dynamically like so:</p>
  
  <pre><code>myButton.titleLabel.text = @"this is the new label";
  </code></pre>
  
  <p>However, when the text updates, the new string is being clipped down to the same size as the original string and ends up looking like:</p>
  
  <pre><code>this...label
  </code></pre>
  
  <p>Anyone know why this is happening?</p>
