如何解决 UIResponder 无法识别的问题？ [复制]

Question

我正在用 Swift 制作记事本应用程序，但遇到以下问题：

类型“Notification.Name”（又名“NSNotification.Name”）没有成员“UIResponder”

这些是我输入的代码行：

@objc func updateTextView (notification : Notification) {
    let userInfo = notification.userInfo!

    let keyboardEndFrameScreenCoordinates = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
    let keyboardEndFrame = self.view.convert(keyboardEndFrameScreenCoordinates, to: view.window)

    if notification.name == Notification.Name.UIResponder.keyboardWillHideNotification {
        textView.contentInset = UIEdgeInsets.zero
    } else {
        textView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardEndFrame.height, right: 0)
        textView.scrollIndicatorInsets = textView.contentInset
    }

    textView.scrollRangeToVisible(textView.selectedRange)
}

if notification.name == UIResponder.keyboardWillHideNotification {
