title: Pinch zooming a UIScrollView on the x-axis only
body: <p>I want to be able to pinch zoom on a UIScrollView, so that subviews expand/contract on the the x-axis only.  </p>
  
  <p>I create a UIScrollView, and using addSubview to add the UIViews. Each UIView has a UILabel in it. Should I be holding on to these UIViews in an array?</p>
  
  <p>When I zoom I don't want the text size to be affected, just the width of each box. I guess I would need minimum and maximum zoom levels too. </p>
  
  <p>Something like this is used in Apple's garageband app. Any idea how to do this?</p>
