如何在ios中实现TableviewCell内部uiTextField中的日期

import UIKit

class DatePickerTableViewCell: UITableViewCell, UITextFieldDelegate {
    let datePicker = UIDatePicker()
    let dateFormatter = DateFormatter()
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        
        // 设置日期选择器的样式和位置
        datePicker.datePickerMode = .date
        datePicker.addTarget(self, action: #selector(datePickerValueChanged(_:)), for: .valueChanged)
        datePicker.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(datePicker)
        
        NSLayoutConstraint.activate([
            datePicker.topAnchor.constraint(equalTo: contentView.topAnchor),
            datePicker.leadingAnchor.constraint(equalTo: contentView.leadingAnchor),
            datePicker.trailingAnchor.constraint(equalTo: contentView.trailingAnchor),
            datePicker.bottomAnchor.constraint(equalTo: contentView.bottomAnchor)
        ])
        
        // 设置日期格式化器
        dateFormatter.dateFormat = "yyyy-MM-dd"
        
        // 设置UITextField的输入视图为日期选择器
        let textField = UITextField()
        textField.delegate = self
        textField.inputView = datePicker
        contentView.addSubview(textField)
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    // UITextFieldDelegate方法，当日期选择器的值改变时更新UITextField的文本
    @objc func datePickerValueChanged(_ sender: UIDatePicker) {
        let dateString = dateFormatter.string(from: sender.date)
        if let textField = contentView.subviews.compactMap({ $0 as? UITextField }).first {
            textField.text = dateString
        }
    }
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = DatePickerTableViewCell(style: .default, reuseIdentifier: "DatePickerCell")
    return cell
}
