使用按钮将文本添加到UITableViewcell中包含的文本字段值

var textArray = ["文本字段值1", "文本字段值2", "文本字段值3"]

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return textArray.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "CellIdentifier", for: indexPath)
    cell.textLabel?.text = textArray[indexPath.row]
    return cell
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "CellIdentifier", for: indexPath)
    cell.textLabel?.text = textArray[indexPath.row]
    
    let button = UIButton(frame: CGRect(x: 10, y: 10, width: 100, height: 30))
    button.setTitle("添加文本", for: .normal)
    button.addTarget(self, action: #selector(addText(_:)), for: .touchUpInside)
    cell.contentView.addSubview(button)
    
    return cell
}

@objc func addText(_ sender: UIButton) {
    guard let cell = sender.superview?.superview as? UITableViewCell else {
        return
    }
    
    guard let indexPath = tableView.indexPath(for: cell) else {
        return
    }
    
    let newText = "新的文本字段值"
    textArray[indexPath.row] = newText
    tableView.reloadRows(at: [indexPath], with: .automatic)
}
