Call a method from anywhere in a tabbar application swift

I have a tabBar application with 4 different ViewControllers. Is it possible to call the same method from all the 4 views, where do I have to put the method? For the record it is just a call to show a iAd banner.

Thanks

Solution

  • This would work. Create a custom subclass of UITabBarController. Put your function in there. Be sure the change the class of the TabBarController in the Storyboard to CustomTabBarController.

    class CustomTabBarController: UITabBarController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    func myFunctionToCallFromAnywhere() {
        print("Hey, it works")
    }
}

    Then in your viewControllers that are managed by your TabBarController you can call the function like this:

    (self.tabBarController as? CustomTabBarController)?.myFunctionToCallFromAnywhere()
