Using Uitabbarcontroller to build the main interface of the project

A: Brief introduction of Uitabbarcontroller:

1. Steps to use:

(1) Initialize Uitabbarcontroller

(2) Set UIWindow Rootviewcontroller to Uitabbarcontroller

(3) Create the corresponding sub-controller (Viewcontroller) (with the child controller as the root view controller of the navigation controller, the outermost wrapper a layer of navigation bar)

(4) Add the controller to the Uitabbarcontroller

2: Join mode: (1)[TB ADDCHILDVIEWCONTROLLER:C1];

(2)[email protected][c1,c2,c3,c4];

Note: The order of presentation is the same as the order of addition, unlike the navigation controller, which is displayed in front of the view that corresponds to the first added controller. The navigation controller is the process of pressing the stack

3.UITabBar

The toolbar below is called Uitabbar, and if the Uitabbarcontroller has n sub-controllers, there will be N Uitabbarbutton as child controls within the Uitabbar.

Note: The position of Uitabbarbutton in Uitabbar is evenly divided, and the height of Uitabbar is 49.

In the above program, Uitabbarcontroller has 4 sub-controllers, so there are 4 uitabbarbutton,uitabbar structures in the Uitabbar, as shown here:

2.UITabBarButton

Uitabbarbutton? What content is determined by the Tabbaritem attribute of the corresponding sub-controller

c1.tabbaritem.title=@ " message "; C1.tabbaritem.image=[uiimage imagenamed:@ "tab_recent_nor"];

Second: The application of Uitabbarcontroller in the project

1: Set the window's root view controller to Cztabbarcontroller
