2. 图片接口

http://www.weather.com.cn/m/i/weatherpic/29x20/d0.gif
http://www.weather.com.cn/m2/i/icon_weather/29x20/n00.gif
这个图就是天气现象0（晴）的图片，其他天气现象的图片依此类推。c打头的图片是20*20像素的，b打头的是50*46像素的，d打头的是反白的图标，29*20像素，n打头的是夜间反白图标，29*20像素，注意这里的文件名是两位数字！ 也许还有更多的图标，等待大家发掘啦~
对于第三个接口，返回信息比较全面，也是以json格式提供，格式如下

3. JSON接口 真没想到~居然有JSON接口~JSON在iPhone上分析起来要比XML简单很多 http://m.weather.com.cn/data/101010200.html 这个是北京的JSON数据，那个HTML的名字是根据上文XML中的url得到的。这个JSON中包含了实时数据、7天天气预报、气象指数等丰富的数据
