在UICollectionView单元格内的胶带按钮上显示视图

// 自定义UICollectionViewCell子类
class CustomCollectionViewCell: UICollectionViewCell {
    var tapeButton: UIButton!
    var contentView: UIView!
    var isViewVisible: Bool = false
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        // 创建胶带按钮
        tapeButton = UIButton(type: .custom)
        tapeButton.frame = CGRect(x: 0, y: 0, width: frame.width, height: frame.height)
        tapeButton.setTitle("Tap to Show View", for: .normal)
        tapeButton.backgroundColor = .blue
        tapeButton.addTarget(self, action: #selector(toggleViewVisibility), for: .touchUpInside)
        addSubview(tapeButton)
        
        // 创建用于显示的视图
        contentView = UIView(frame: CGRect(x: 0, y: frame.height, width: frame.width, height: 100))
        contentView.backgroundColor = .green
        addSubview(contentView)
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    // 切换视图的显示状态
    @objc func toggleViewVisibility() {
        isViewVisible = !isViewVisible
        contentView.isHidden = !isViewVisible
    }
}

// 在UICollectionView的数据源方法中使用自定义单元格类
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCollectionViewCell
    
    // 设置需要显示的视图内容
    let label = UILabel(frame: CGRect(x: 10, y: 10, width: 100, height: 30))
    label.text = "Hello"
    cell.contentView.addSubview(label)
    
    return cell
