title: Pinch-to-zoom UILabel
body: <p>I'm handling a pinch gesture, and I am scaling a <code>UILabel</code> like this:</p>
  
  <pre><code>CGFloat factor = sender.scale;
  view.transform = CGAffineTransformScale(view.transform, factor, factor);
  </code></pre>
  
  <p>The problem is when I zoom-in (make the label larger) it wont redraw itself, i.e. it becomes blurry. How do I make it sharp again?</p>
