如何在具有动态大小的collectionViewCell中使用scrollView

class CustomCollectionViewCell: UICollectionViewCell {
    let scrollView = UIScrollView()
    let contentView = UIView()
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        // 添加scrollView
        contentView.translatesAutoresizingMaskIntoConstraints = false
        scrollView.addSubview(contentView)
        contentView.leadingAnchor.constraint(equalTo: scrollView.leadingAnchor).isActive = true
        contentView.trailingAnchor.constraint(equalTo: scrollView.trailingAnchor).isActive = true
        contentView.topAnchor.constraint(equalTo: scrollView.topAnchor).isActive = true
        contentView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor).isActive = true
        contentView.widthAnchor.constraint(equalTo: self.widthAnchor).isActive = true
        
        // 添加需要展示的内容
        let imageView = UIImageView(image: UIImage(named: "image"))
        imageView.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(imageView)
        imageView.leadingAnchor.constraint(equalTo: contentView.leadingAnchor).isActive = true
        imageView.trailingAnchor.constraint(equalTo: contentView.trailingAnchor).isActive = true
        imageView.topAnchor.constraint(equalTo: contentView.topAnchor).isActive = true
        imageView.heightAnchor.constraint(equalToConstant: 200).isActive = true
        
        let label = UILabel()
        label.text = "Some text"
        label.translatesAutoresizingMaskIntoConstraints = false
        contentView.addSubview(label)
        label.leadingAnchor.constraint(equalTo: contentView.leadingAnchor).isActive = true
        label.trailingAnchor.constraint(equalTo: contentView.trailingAnchor).isActive = true
        label.topAnchor.constraint(equalTo: imageView.bottomAnchor, constant: 10).isActive = true
        
        // 设置scrollView的属性
        scrollView.translatesAutoresizingMaskIntoConstraints = false
        scrollView.showsVerticalScrollIndicator = false
        scrollView.showsHorizontalScrollIndicator = false
        scrollView.contentSize = contentView.bounds.size
        
        // 添加scrollView到collectionViewCell
        contentView.addSubview(scrollView)
        scrollView.leadingAnchor.constraint(equalTo: self.leadingAnchor).isActive = true
        scrollView.trailingAnchor.constraint(equalTo: self.trailingAnchor).isActive = true
        scrollView.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
        scrollView.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

// 在collectionView的数据源方法中计算collectionViewCell的大小
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
    // 根据内容的大小来确定collectionViewCell的高度
    let cellWidth = collectionView.bounds.width
    let cellHeight: CGFloat = 250 // 根据具体需求设置高度
    return CGSize(width: cellWidth, height: cellHeight)
}
