UITabBarController is possible to select the tab via code?

Question

难道UITabBarController可以在代码中选择选项卡吗？比如UINavigationController我们可以使用popViewController弹出回rootViewController而不是按下后退按钮，那么如何在tabbarcontroller中实现呢？

Answer 1

Use the selectedIndex property on the UITabBarController. More information can be found in the UITabBarController Class Reference .

controller.selectedIndex = 4;

or use

[controller setSelectedIndex:4];
