title: UIlabel layer.cornerRadius not working in iOS 7.1
body: <p>I'm currently looking at a UILabel with the property <code>addMessageLabel.layer.cornerRadius = 5.0f;</code> On a device with iOS 7.0 installed, it has rounded corners. On a device with iOS 7.1 installed, it does not have rounded corners.</p>
  
  <p>Is this just a bug with iOS 7.1?</p>
