如何在UITabbarViewController中的不同视图之间切换

Question

I tried to use the below code to do the switch:

 [self.tabBarController setSelectedIndex:1];

I notice when I put this in viewDidLoad ... nothing happened. But when I put in separate method, for example, when a button is clicked, it works.

any body know why?

Answer 1

What are you trying to achieve? To manually set the tab being displayed I just set the tab bar's selectedIndex .
