UITableView内部的UIPickerView值(基于DateCell)更改detailLabel

import UIKit

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UIPickerViewDelegate, UIPickerViewDataSource {
    
    let tableView = UITableView()

        tableView.frame = view.bounds
        view.addSubview(tableView)
        
        datePicker.datePickerMode = .date
        datePicker.addTarget(self, action: #selector(datePickerValueChanged), for: .valueChanged)
    }
    
    // MARK: - UITableViewDataSource
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 1
    }

        return cell
    }
