如何在单击按钮时获取和传递UICollectionViewCell

// 自定义UICollectionViewCell类
class CustomCollectionViewCell: UICollectionViewCell {
    var button: UIButton!
    weak var delegate: CustomCollectionViewCellDelegate?
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        // 创建和设置按钮
        button = UIButton(type: .system)
        button.frame = contentView.bounds
        button.addTarget(self, action: #selector(buttonClicked(_:)), for: .touchUpInside)
        contentView.addSubview(button)
    }
    
    @objc func buttonClicked(_ sender: UIButton) {
        // 获取按钮所在的UICollectionViewCell
        guard let cell = sender.superview as? CustomCollectionViewCell else {
            return
        }
        
        // 获取UICollectionViewCell的indexPath
        guard let indexPath = delegate?.collectionViewCellIndexPath(cell) else {
            return
        }
        
        // 将UICollectionViewCell的信息传递给代理
        delegate?.collectionViewCellDidTapButton(cell, at: indexPath)
    }
}

// 自定义UICollectionViewCell代理协议
protocol CustomCollectionViewCellDelegate: AnyObject {
    func collectionViewCellDidTapButton(_ cell: CustomCollectionViewCell, at indexPath: IndexPath)
    func collectionViewCellIndexPath(_ cell: CustomCollectionViewCell) -> IndexPath?
}

// 视图控制器实现UICollectionViewDelegate和UICollectionViewDataSource协议
class ViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource, CustomCollectionViewCellDelegate {
    var collectionView: UICollectionView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建和设置UICollectionView
        let layout = UICollectionViewFlowLayout()
        collectionView = UICollectionView(frame: view.bounds, collectionViewLayout: layout)
        collectionView.delegate = self
        collectionView.dataSource = self
        collectionView.register(CustomCollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
        view.addSubview(collectionView)
    }
    
    // UICollectionViewDelegate和UICollectionViewDataSource方法的实现
    
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10
    }
    
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! CustomCollectionViewCell
        cell.delegate = self
        return cell
    }
    
    // CustomCollectionViewCellDelegate方法的实现
    
    func collectionViewCellDidTapButton(_ cell: CustomCollectionViewCell, at indexPath: IndexPath) {
        // 在这里处理按钮点击事件，可以获取到UICollectionViewCell的信息
    }
    
    func collectionViewCellIndexPath(_ cell: CustomCollectionViewCell) -> IndexPath? {
        return collectionView.indexPath(for: cell)
    }
}
