title: How to read log output of NSAutoresizingMaskLayoutConstraint?
body: <p>I see the following output in console</p>
  
  <pre><code>"&lt;NSAutoresizingMaskLayoutConstraint:0x100510500 h=--&amp; v=&amp;-- H:|-(0)-[NSView]
      (Names: NSView:0x1016ab760, '|':NSClipView:0x1016a26b0 )&gt;
      (Actual Distance - pixels):0"
  </code></pre>
  
  <p>Normally I understand how to read log message for constraints. But autoresizingMask constraints always confuse me. How does the following characters in the log output correspond to auto-resizing mask? </p>
  
  <p><code>h=--&amp; v=&amp;-- H:|-(0)-[NSView]</code></p>
  
  <p>I watched several WWDC 2012 videos which didn't quite explain reading auto-resizing mask layout constraints. </p>
