title: How to find pinch in or pinch out using Gestures events in IOS safari in jquery?
body: <p>I want to implement Pinch In and Out functionality for IPAD. I've been using this events listed on <a href="http://developer.apple.com/library/IOs/#documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html" rel="nofollow">http://developer.apple.com/library/IOs/#documentation/AppleApplications/Reference/SafariWebContent/HandlingEvents/HandlingEvents.html</a>. </p>
  
  <pre><code>$('div.mainContainer').live("gesturestart", function(e){
     alert("start " + e.originalEvent.scale);
  });
  $('div.mainContainer').live("gesturechange", function(e){
     alert("change " + e.originalEvent.scale);
     e.preventDefault();
  });
  </code></pre>
  
  <p>The above code works but could not figure out the pinch in/out. </p>
  
  <p>P.S. I've tried <a href="http://jgestures.codeplex.com/" rel="nofollow">jGestures</a> but it does not work at all. </p>
