- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController{ if (viewController.tabBarController == nil) { img.hidden = YES; NSLog(@"Tab Bar Button"); } }

Do you know that

In versions of iOS prior to version 3.0, this method is called only when the selected view controller actually changes. In other words, it is not called when the same view controller is selected.

In addition to this, make sure you are hiding the imageView that contains the image.

UPDATE

Get the tabBarController instance in the view controller and make its delegate the view controller. Then you can call this method in the view controller.

give name for the tabbarcontroller and then set the delegate for that.If my suggestion not useful,then ask me freely
