Switching to a TabBar tab view programmatically?

Question

Let\'s say I have a UIButton in one tab view in my iPhone app, and I want to have it open a different tab in the tab bar of the TabBarController.

Answer 1

Use in AppDelegate.m file:

(void)tabBarController:(UITabBarController *)tabBarController
 didSelectViewController:(UIViewController *)viewController
{

     NSLog(@"Selected index: %d", tabBarController.selectedIndex);

    if (viewController == tabBarController.moreNavigationController)
    {
        tabBarController.moreNavigationController.delegate = self;
    }

    NSUInteger selectedIndex = tabBarController.selectedIndex;

    switch (selectedIndex) {

        case 0:
            NSLog(@"click me %u",self.tabBarController.selectedIndex);
            break;
        case 1:
            NSLog(@"click me again!! %u",self.tabBarController.selectedIndex);
            break;

        default:
            break;

    }

}
