IOS Imitation Hot Topic hot wheel-Seeding interface Tableview_ios

Nonsense not much to say directly on the code:

This feature should be quite common, a tableview to another tableview, something like segment, which I encapsulated:

This is easy to understand, is not, it is not here to explain more.

The one on the top. is to hide the navigation bar, customize a small uiview to intercept the network image as a navigation bar, and customize a large view as a TableView header view. And I also used the Observer Registration message notification, the code is a bit long, but I write a note oh, can understand.
