如何在swift中的自定义单元格的按钮点击上传递附加项目？

// CustomCell.swift
protocol CustomCellDelegate: AnyObject {
    func didTapButton(in cell: CustomCell)
}

class CustomCell: UITableViewCell {
    @IBOutlet weak var button: UIButton!
    weak var delegate: CustomCellDelegate?

    @IBAction func buttonTapped(_ sender: UIButton) {
        delegate?.didTapButton(in: self)
    }
}

// ViewController.swift
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, CustomCellDelegate {
    // ...

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath) as! CustomCell
        cell.delegate = self
        cell.button.setTitle("Upload", for: .normal)
        // Configure other cell properties
        return cell
    }

    func didTapButton(in cell: CustomCell) {
        guard let indexPath = tableView.indexPath(for: cell) else { return }
        // Handle button tap and upload additional item for the corresponding indexPath
    }

    // ...
}
