swift中集合视图单元格内的按钮操作

import UIKit

class CustomCell: UICollectionViewCell {
    var button: UIButton!

    override init(frame: CGRect) {
        super.init(frame: frame)
        
        button = UIButton(type: .system)
        button.frame = CGRect(x: 0, y: 0, width: 100, height: 40)
        button.setTitle("按钮", for: .normal)
        button.addTarget(self, action: #selector(buttonTapped), for: .touchUpInside)
        
        contentView.addSubview(button)
    }
    
    @objc func buttonTapped() {
        // 处理按钮点击事件
        print("按钮被点击了！")
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }
}

class ViewController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource {
    var collectionView: UICollectionView!
    let cellIdentifier = "Cell"
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let layout = UICollectionViewFlowLayout()
        collectionView = UICollectionView(frame: view.frame, collectionViewLayout: layout)
        collectionView.delegate = self
        collectionView.dataSource = self
        collectionView.register(CustomCell.self, forCellWithReuseIdentifier: cellIdentifier)
        
        view.addSubview(collectionView)
    }

        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: cellIdentifier, for: indexPath) as! CustomCell
        
        // 可以设置其他单元格内容
