The most straightforward way is the UITabBarDelegate. Sorry. Implement your class and inherit the protocol by adding after your class definition e.g.:

@interface MyViewController : UIViewController

and then define the method tabBar:didSelectItem: in that class e.g.

- (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item {
    // Do Stuff!
    // if(item.title == @"First") {...}
}

Then set the delegate on your tabbar like so: myTabBar.delegate = myClassInstance. The tabBar:didSelectItem: method can be anywhere including your view controller and is where you will get the event that the button was clicked. More info here:
