如何在UICollectionViewController中显示一个可滚动的行

import UIKit

class MyCollectionViewController: UICollectionViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 设置布局属性
        let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .vertical
        layout.minimumLineSpacing = 10
        layout.itemSize = CGSize(width: 100, height: 100)
        collectionView.collectionViewLayout = layout
        
        // 注册自定义的单元格
        collectionView.register(MyCollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
    }
    
    override func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10 // 返回行数
    }
    
    override func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! MyCollectionViewCell
        // 配置每个单元格的内容
        cell.textLabel.text = "Row \(indexPath.row)"
        return cell
    }
}

class MyCollectionViewCell: UICollectionViewCell {
    let textLabel: UILabel
    
    override init(frame: CGRect) {
        textLabel = UILabel(frame: CGRect(x: 0, y: 0, width: frame.width, height: frame.height))
        super.init(frame: frame)
        
        contentView.addSubview(textLabel)
        contentView.backgroundColor = .white
    }
    
    required init?(coder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}
