    <script type="text/javascript" charset="utf-8"> 

     body = document.getElementById('body'); 

     // (in percents) 
     zoom = 100; 
     maxZoom = 200; 
     minZoom = 50; 
     zoomIncrement = 25; 

     function gestureEnd(event) { 
      var newZoom; 
      if (event.scale > 1.0) { 
       // increase size 
       newZoom = zoom + zoomIncrement; 
      } else { 
       // decrease size 
       newZoom = zoom - zoomIncrement; 
      } 

      // don't exceed zoom boundaries 
      if (newZoom > maxZoom || newZoom < minZoom) { 
       return; 
      } 
      zoom = newZoom; 
      body.style.webkitTextSizeAdjust = zoom+"%"; 
     } 

     body.addEventListener("gestureend", gestureEnd, false); 

     </script>

我怎麼可以具有的WebView焦距可變值每捏事件（更改APP中的默認值）??

一類的「回調」由JS到App方法..

如果你想獲得一個JS變量的值在應用原生的OBJ-C使用，也許你可以使用stringByEvaluatingJavaScriptFromString方法。
