答
您最有可能想利用UITabBarControllerDelegate，然后处理didSelectViewController方法。
You most likely want to take advantage of the UITabBarControllerDelegate, and then handle the didSelectViewController method.
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
