如何使UITextField与键盘向上移动同步？

Question

我在UITextField中嵌入了UIScrollView。当键盘出现时，文本字段被键盘隐藏。

[我使用以下代码为UIResponder.keyboardWillShowNotification和UIResponder.keyboardWillHideNotification设置观察者，并相应地设置contentInset的UIScrollView。

extension ViewController {
    func addKeyboardNotificationsObserver() {
        NotificationCenter.default.addObserver(
            self,
            selector: #selector(keyboardWillBeShown(notification:)),
            name: UIResponder.keyboardWillShowNotification,
            object: nil
        )
        NotificationCenter.default.addObserver(
            self,
            selector: #selector(keyboardWillBeHidden(notification:)),
            name: UIResponder.keyboardWillHideNotification,
            object: nil
        )
    }
    @objc func keyboardWillBeShown(notification: NSNotification) {
        guard
            let kbRect = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? CGRect,
            let duration = notification.userInfo?[UIResponder.keyboardAnimationDurationUserInfoKey] as? NSNumber,
            let curve = notification.userInfo?[UIResponder.keyboardAnimationCurveUserInfoKey] as? NSNumber
        else { return }

        let insets = UIEdgeInsets(top: 0, left: 0, bottom: kbRect.height, right: 0)

        UIView.animate(
            withDuration: duration.doubleValue,
            delay: .zero,
            options: .init(rawValue: curve.uintValue << 16),
            animations: {
                self.scrollView.contentInset = insets
                self.scrollView.scrollIndicatorInsets = insets
            },
            completion: nil
        )
    }
    @objc func keyboardWillBeHidden(notification: NSNotification) {
        scrollView.contentInset = .zero
        scrollView.scrollIndicatorInsets = .zero
    }
}

该代码有效。但是，当键盘出现时，文本字段会暂时被部分隐藏。文本字段似乎在动画结尾附近跳起来。

[谁能指出解决此问题的方法，以使文本字段与即将出现的键盘同步向上移动，并且在动画快结束时不会显示为向上跳跃？

我在UIScrollView中嵌入了一个UITextField。当键盘出现时，文本字段被键盘隐藏。我使用以下代码为UIResponder设置观察者。...
