ios - 键盘显示额外空间 Swift

Question

原始屏幕截图:

1.当键盘不可见时:

这很好。

2. 问题是当键盘出现时，上面的图像从 textView 和键盘的原始位置向上移动，如下所示:

这是我正在尝试做的事情:

代码:

  func addKeyboardObservers() {
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
}

// MARK: - remove Keyboard Observers
func removeKeyboardObservers() {
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillShowNotification, object: nil)
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
}

// MARK: - keyboard show
@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height - bottomLayoutGuide.length
        UIView.animate(withDuration: 0.25, animations: {() -> Void in
            self.bottomConstraint.constant = keyboardHeight
            self.view.layoutIfNeeded()
        }, completion: nil)
    }
}

// MARK: - keyboard hide
@objc func keyboardWillHide(_ notification: Notification) {
    view.layoutIfNeeded()
 }

当我使用这段代码时，给我看下面给出的空白屏幕截图:

当我评论下面这些行的屏幕截图时:

// MARK: - keyboard show

@objc func keyboardWillShow(_ notification: Notification) {
   // if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
    //    let keyboardRectangle = keyboardFrame.cgRectValue
     //   let keyboardHeight = keyboardRectangle.height - bottomLayoutGuide.length
      //  UIView.animate(withDuration: 0.25, animations: {() -> Void in
       //     self.bottomConstraint.constant = keyboardHeight
       //     self.view.layoutIfNeeded()
      // }, completion: nil)
  //  }
}

这是我的主 Storyboard屏幕截图:

有人可以向我解释如何解决这个问题吗，我已经尝试解决这个问题但还没有结果。

如有任何帮助，我们将不胜感激。

提前致谢。
