title: UIButton - text truncated
body: <p>I've created a wide UIButton with Interface Builder (Xcode 4), added in a dummy 5 character title (e.g. Click) and then changed the title text programmatically later.</p>
  
  <p>Odd thing is the width of the title text seems to remain the same so, if I use a longer piece of text (e.g. "Now click here"), it appears like this: "N...e"</p>
  
  <p>Any idea what's going on?</p>
  
  <p>UPDATE:
  If I use a long line of text in IB it's centred. However, once I've programmatically-changed this text it appears left-aligned! </p>
