1.话说，本来想做个聚合查询功能。可是我的重点想研究xmpp聊天功能。所以使用mvvm模式做了全然模式51job主界面的页面。
2.首先给大家看我执行起来的界面。
3.界面非常easy，做这个界面主要是为了比較mvvm模式和mvc模式之间的差别。
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，别人维护起来非常麻烦。
我就不贴viewcontroller的图片了，我把这个代码上传给大家，大家能够看看，和mvc相比，是不是非常easy维护。代码层级会好一些。明天開始研究iosxmpp的聊天功能，所以会暂停一段时间更新。
没办法，看来仅仅能贴代码了，我仅仅贴viewcontroller和viewmodel的代码。大家能够比較下。
这是viewcontroller
