ios UITabBarController change to another UITabBarController

Question

Is it possible to redesign a UITabBarController when clicking on a UITabBarItem?

When starting the app I want to have 5 UITabBarItems:

self.myTabBarController = [CustomTabbarControllerViewController alloc] init];
self.myTabBarController.viewControllers = @[controller1, controller2, controller3, controller4, controller5];
..

When I ll click on controller2 I would like myTabBarController.viewController to contain controllerA, controllerB, controllerC . controllerA will bring the previous tabBarController.

I tried to find some examples on the internet, but i couldn t find any.

Answer 1

You can make 2 tabBarController and make then hidden and show. If you do this thing in single TabBarController then it will remove and add your viewController all time.

So best way to do is use 2 tabBarController in appDelegate.
