如何在tableviewCell中使用单击操作更改2个UIButton图像

@IBOutlet weak var button1: UIButton!
@IBOutlet weak var button2: UIButton!

@IBAction func buttonTapped(_ sender: UIButton) {
    // 在这里处理按钮点击事件
    if sender == button1 {
        // 更改button1的图像
        button1.setImage(UIImage(named: "image1_selected"), for: .normal)
        button2.setImage(UIImage(named: "image2_normal"), for: .normal)
    } else if sender == button2 {
        // 更改button2的图像
        button1.setImage(UIImage(named: "image1_normal"), for: .normal)
        button2.setImage(UIImage(named: "image2_selected"), for: .normal)
    }
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifier", for: indexPath) as! CustomTableViewCell
    
    // 设置按钮的点击事件
    cell.button1.addTarget(cell, action: #selector(cell.buttonTapped(_:)), for: .touchUpInside)
    cell.button2.addTarget(cell, action: #selector(cell.buttonTapped(_:)), for: .touchUpInside)
    
    return cell
}
