如何在iOS 14中实现具有自定义内容配置的文本字段单元格？

import UIKit

class CustomTextFieldCell: UITableViewCell {
    
    let textField = UITextField()
    
    override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
        super.init(style: style, reuseIdentifier: reuseIdentifier)
        setupViews()
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    private func setupViews() {
        contentView.addSubview(textField)
        
        textField.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            textField.leadingAnchor.constraint(equalTo: contentView.leadingAnchor, constant: 16),
            textField.trailingAnchor.constraint(equalTo: contentView.trailingAnchor, constant: -16),
            textField.centerYAnchor.constraint(equalTo: contentView.centerYAnchor)
        ])
    }
    
    func configure(with placeholder: String) {
        textField.placeholder = placeholder
    }
}

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    
    let tableView = UITableView()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupTableView()
    }
    
    private func setupTableView() {
        tableView.dataSource = self
        tableView.delegate = self
        tableView.register(CustomTextFieldCell.self, forCellReuseIdentifier: "CustomTextFieldCell")
        
        view.addSubview(tableView)
        tableView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            tableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor),
            tableView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor),
            tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor),
            tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor)
        ])
    }
    
    // MARK: - UITableViewDataSource
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5 // 假设有5行数据
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomTextFieldCell", for: indexPath) as! CustomTextFieldCell
        cell.configure(with: "Enter text \(indexPath.row + 1)")
        return cell
    }
}
