title: CGAffineTransforms on NSViews
body: <p>I am trying to port some iOS code to Mac OS X. I am having trouble porting this though,</p>
  
  <pre><code>CGAffineTransform transform = CGAffineTransformMakeRoatation(-b-&gt;GetAngle());    
  oneView.transform = transform
  </code></pre>
  
  <p>How can I achieve this? The NSView doesn't have a transform property.</p>
