如何修复tableView重新加载时的键盘问题？

// 监听键盘显示和隐藏的通知
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow(_:)), name: UIResponder.keyboardWillShowNotification, object: nil)
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(_:)), name: UIResponder.keyboardWillHideNotification, object: nil)

// 键盘显示时的处理方法
@objc func keyboardWillShow(_ notification: Notification) {
    guard let keyboardFrame = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? CGRect else {
        return
    }
    let keyboardHeight = keyboardFrame.height
    
    // 调整tableView的contentInset.bottom
    tableView.contentInset.bottom = keyboardHeight
}

// 键盘隐藏时的处理方法
@objc func keyboardWillHide(_ notification: Notification) {
    // 还原tableView的contentInset.bottom
    tableView.contentInset.bottom = 0
}
