title: Appearance Proxies & Layers
body: <p>Is it possible to use iOS 5 appearance proxies to refactor code that sets properties on layers?</p>
  
  <pre><code>_button.layer.cornerRadius = 5.0f;
  _button.layer.borderWidth = 1.0f;
  _button.layer.borderColor = [[UIColor blackColor] CGColor];
  _button.layer.masksToBounds = YES;
  </code></pre>
