1.话说，本来想做个聚合查询功能，但是我的重点想研究xmpp聊天功能。所以使用mvvm模式做了完全模式51job主界面的页面。
2.首先给大家看我运行起来的界面。
3.界面很简单，做这个界面主要是为了比较mvvm模式和mvc模式之间的区别。
4.这个界面的结构是下边这张图片
与mvc相比，我多了一个viewmodel文件。
mvc之前是把业务逻辑和数据放在viewcontroller里边，逻辑复杂的话，别人维护起来很麻烦。
我就不贴viewcontroller的图片了，我把这个代码上传给大家，大家可以看看，和mvc相比，是不是很容易维护，代码层级会好一些。明天开始研究iosxmpp的聊天功能，所以会暂停一段时间更新。
没办法，看来只能贴代码了，我只贴viewcontroller和viewmodel的代码，大家可以比较下。
这是viewcontroller
