Question

I don’t use UITabbarController,I just add the UITabbar in ViewController.I know when we use UITabbarController,we will create one array which contain viewcontrollers,so when we tap the tab,will show the specific viewcontroller,but the UITabbar just can add UITabbarItems,so how to connect the viewcontroller to the Tab?just like UITabbarController. thank you in advance.

Answer 1

Attach a UITabBarDelegate to your UITabBar:

self.tabbar.delegate = self; 
// make sure you declared self to be a UITabBarDelegate in your header

Then implement:

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item {
  // item is the selected tab bar item
}
