数据格式之解析Json

这里就不转正文了，以后点击链接看看。。。
但有个问题，他介绍的几种格式并没有我想要的；从服务器上得到的json格式是这样的：
[{"description":"\u5e7f\u544a3","img":"http:\/\/clostyle2012.eicp.net\/images\/appimg\/ad\/3.jpg","link":"34"},{"description":"\u5e7f\u544a2","img":"http:\/\/clostyle2012.eicp.net\/images\/appimg\/ad\/2.jpg","link":"33"},{"description":"\u5e7f\u544a1","img":"http:\/\/clostyle2012.eicp.net\/images\/appimg\/ad\/1.jpg","link":"32"}]
一看就知道，外边就是一个JSONArray，元素是三个JSONObject对象。但是数组没有键，就不能按上面那篇文章讲的啦。我找了半天，实验了很多次，终于搞定了。但是不知道是不是最好的。
他文章中的例子格式和我要的一样，我用了它代码中的一部分。。。
