呈现新的viewController后保持键盘打开

Question

How to keep the keyboard opened if presenting new viewController?

I have 2 viewcontrollers: firstVC , secondVC . firstVC has textfield and secondVC has it also. Now if I present secondVC from firstVC I want the keyboard to be opened but it dismisses it.

According to documentation I tried overriding the disablesAutomaticKeyboardDismissal which is not working for some reason:

override var disablesAutomaticKeyboardDismissal: Bool {
    return true
}

What else I should do? I do not want that it dismisses then assign becomeFirstResponder() because it makes nasty animation.

I know that if you want to keep keyboard opened if you present for example an UIAlertView then you can do this:

let rootViewController: UIViewController = (UIApplication.shared.windows.last?.rootViewController)!
        rootViewController.presentViewController(alert, animated: true, completion: nil)

txtcode.becomeFirstResponder()在txtcode中替换您的文本字段名称，并为相同的名称提供委托
