在 iOS 13 中关闭键盘后，safeAreaInsets 更改其值

如何解决在 iOS 13 中关闭键盘后，safeAreaInsets 更改其值

我有 bottomView（图像中带有黑色边框的那个）它的底部锚点对底部视图 safeAreaLayoutGuide 有约束，但是当键盘显示时，bottomView 变成了键盘的工具栏。

这里的一切都在 iOS 14 中按预期工作（如图像 1 和 3）但是在 iOS 13 中运行项目时，我发现 safeAreaInsets 在键盘关闭（红色空间增加其高度，如图像 2）

我尝试了一些提到 here 的解决方案，但没有帮助任何人都可以为此提出解决方案吗？

 @objc func adjustForKeyboard(notification: Notification) {
        guard let keyboardValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue else { return }

        let keyboardScreenEndFrame = keyboardValue.cgRectValue
        let keyboardViewEndFrame = view.convert(keyboardScreenEndFrame,from: view.window)
        if notification.name == UIResponder.keyboardWillHideNotification {
            bottomViewConstraint?.constant = 0
            NotesText.contentInset = .zero
        
        } else {
            
            bottomViewConstraint?.constant = -(keyboardViewEndFrame.height - self.view.safeAreaInsets.bottom)
            NotesText.contentInset = UIEdgeInsets(top: 0,left: 0,bottom: -(keyboardViewEndFrame.height + bottomViewConstraint!.constant),right: 0)
            //FIXME:- force unwrap
        }

        NotesText.scrollIndicatorInsets = NotesText.contentInset

        let selectedRange = NotesText.selectedRange
        NotesText.scrollRangetoVisible(selectedRange)
        
        
    }

并在 viewDidAppear 中调用此函数也尝试在 viewSafeAreaInsetsDidChange 中调用它但行为没有改变

 override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        addKeyboardNotification()
        
        // Show keyboard by default
        NotesText.becomeFirstResponder()
    }

键盘通知功能：

 fileprivate func addKeyboardNotification() {

        let notificationCenter = NotificationCenter.default

        notificationCenter.addobserver(self,selector: #selector(adjustForKeyboard),name: UIResponder.keyboardWillHideNotification,object: nil)
        notificationCenter.addobserver(self,name: UIResponder.keyboardWillChangeFrameNotification,object: nil)

    }
