当我在UITextField中输入文本时，整个视图的位置会上移

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)

@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardFrame = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? CGRect {
        let keyboardHeight = keyboardFrame.height
        // 计算需要上移的距离
        let moveDistance = keyboardHeight - (view.frame.height - textField.frame.maxY)
        // 执行上移动画
        UIView.animate(withDuration: 0.3) {
            self.view.transform = CGAffineTransform(translationX: 0, y: -moveDistance)
        }
    }
}

@objc func keyboardWillHide(_ notification: Notification) {
    // 执行恢复动画
    UIView.animate(withDuration: 0.3) {
        self.view.transform = .identity
    }
}
