How can I make a subclass of UITabBarController inherit from UIViewController too?

Question

I am using a third party SDK which provides a custom UIViewController . I am not sure of the exact functionality since it's closed source.

I want to create a subclass of UITabBarController that also inherits the functionality from the third party UIViewController. Is that possible using Swift ?

Answer 1

No, Swift only supports single inheritance of superclasses, and multiple inheritance of protocols. You could use delegation though - delegate to one of the classes in question. Without knowing your intents, it hard to be more specific. From the face of it though, it feels like a bad idea from the outset, I would look for cleaner high level solution.

Answer 2

You shouldn't need to subclass UITabBarController . Instead create a UITabBarController and set an instance of the custom view controller class as one of it's view controllers:

tabBarController.setViewControllers([viewController], NO)
