The default controller in system storyboard is: Viewcontroller

In this case, if the entire program interface is only built using UITableView, then it is generally necessary to complete the following relatively tedious steps:

(1) Drag a uitableview to the interface

(2) Setting up a data source

(3) Set up Agent

(4) Compliance with agency agreements

The above process is relatively cumbersome, and also need to manually set up data sources, agents, compliance protocol, etc., easy to omit, the following recommended direct use of UITableView Controller.   ii. use of UITableView Controllerto simplify the operation, the following method is introduced. that is, if you only need to display a uitableview on the interface, you can have the host controller directly inherit from the UITableView controller

 Just let the controller inherit uitableview controllers, then delete the previous interface in storyboard, and drag a TableView controller.  Note: You need to associate with the host controller class. The UITableView controller has a TableView property in it, and the view obtained through Self.view in the controller is a tableview. that is Self.view=self.taleview. and it has already implemented his protocols and data sources by default, and no longer needs to be wired.

Right-click to find that the data source and the agent are already connected.  (the controller that inherits from Uiviewcontroller should be killed, and a tableview controller should be dragged back to connect with the master.) )
