iOS UIInputViewController：呈现自定义UIViewController + NIB

Question

I've a keyboard extension and want to present a custom UIViewController with a NIB file inside an UIInputViewController. I already made some custom keyboards with ObjectiveC in the past. There I could set a UiNavigationController to the UIInputViewController. But it seems that this is not possible anymore.

• Does anyone knows how to do that?
• Or does anyone knows a good tutorial?

Here is some sample code that doesn't work.

class KeyboardViewController: UIInputViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    let controller: MyViewController = MyViewController()
    self.present(controller, animated: false, completion: nil)
}

...
}

Answer 1

I have solved my problem:

I just put the code into viewDidAppear instead of viewDidLoad

override func viewDidAppear(_ animated: Bool) {
    let controller: MyViewController = MyViewController()
    self.present(controller, animated: false, completion: nil)
}
