如何在UICollectionView中为按钮添加addTarget？

class CustomCollectionViewCell: UICollectionViewCell {
    var button: UIButton!

    override init(frame: CGRect) {
        super.init(frame: frame)
        
        // 创建按钮
        button = UIButton(type: .system)
        button.frame = contentView.bounds
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        
        // 添加按钮到单元格
        contentView.addSubview(button)
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    @objc func buttonTapped() {
        // 按钮点击事件处理
    }
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCollectionViewCell
    
    // 设置按钮的目标和动作
    cell.button.addTarget(self, action: #selector(buttonTapped(_:)), for: .touchUpInside)
    
    return cell
}

@objc func buttonTapped(_ sender: UIButton) {
    // 按钮点击事件处理
    guard let indexPath = collectionView.indexPath(for: sender.superview as! UICollectionViewCell) else {
        return
    }
    
    // 根据indexPath获取相关数据或执行其他操作
}
