TabBarController viewDidAppear 在呈现的视图控制器关闭时未调用

Question

I am trying present a navigation controller with UITabBarController, I am confused why UITabBarController's viewDidAppear is not called again after the navigation controller dismissed. How can I manage to do that?

Answer 1

Change presentation style to currentContext . For example:

let controller = ViewController()
controller.modalPresentationStyle = .currentContext //<-- Add this line
self.present(controller, animated: true, completion: nil)
