从tableview Swift获取点击按钮的标签值

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
    
    // 添加按钮
    let button = UIButton(type: .system)
    button.frame = CGRect(x: 0, y: 0, width: 100, height: 30)
    button.setTitle("点击", for: .normal)
    button.tag = indexPath.row // 设置按钮的标签值为cell的索引值
    button.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
    
    cell.contentView.addSubview(button)
    
    return cell
}

@objc func buttonTapped(_ sender: UIButton) {
    let tag = sender.tag // 获取按钮的标签值
    
    // 根据标签值进行相应的操作
    print("点击的按钮标签值为：\(tag)")
}
