wp7天气预报源代码（二获取谷歌天气数据）公布源代码下载地址

在上一篇文章里已经介绍了这个应用

文章源地址：http://www.cnblogs.com/wildfeng/archive/2012/03/21/2410504.html

由于代码过多，和繁杂的前台页面效果代码，没办法在博文中说明白，还有很多网友要求我公布源代码项目。在文章的最下面我提供了源代码的下载地址。

这个天气预报用的是谷歌的API，我特意写了个工具类用来解析谷歌天气数据，本文中主要介绍这个工具类。

代码如下：

在以后的博文里我会详细讲解这个应用UI方面的实现，毕竟这个应用亮点全在UI上面。我个人是这么理解的，因为功能代码不是很难，UI的效果比较炫。我用了Storyboard来实现了一些效果。
