1. So if you are using a UITabBarController you can make the class implement the UITabBarControllerDelegate and set your UITabBarController delegate to the class that needs to be notified when the TabBar selected item changes, then add the delegate method to your class:

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

Inside this method you can use the UITabBarController selectedIndex property to know which is the current index selected:

-(void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:      (UIViewController *)viewController
{
    NSLog(@"Selected index: %d", tabBarController.selectedIndex);
}

2. If you are not using just the UITabBar you can follow the answer here by Ken Pespisa and iCoder in this post Ken Pespisa and iCoder in this post.
