是否可以在UIScrollView中平铺图像而无需手动创建所有图块？

import UIKit

let flowLayout = UICollectionViewFlowLayout()

flowLayout.itemSize = CGSize(width: 100, height: 100)
flowLayout.scrollDirection = .vertical

let collectionView = UICollectionView(frame: CGRect.zero, collectionViewLayout: flowLayout)

collectionView.dataSource = self
collectionView.delegate = self

collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 数据源数组.count
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath)
    let image = 数据源数组[indexPath.item]
    cell.backgroundColor = UIColor(patternImage: image)
    return cell
}

addSubview(collectionView)
collectionView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    collectionView.topAnchor.constraint(equalTo: topAnchor),
    collectionView.bottomAnchor.constraint(equalTo: bottomAnchor),
    collectionView.leadingAnchor.constraint(equalTo: leadingAnchor),
    collectionView.trailingAnchor.constraint(equalTo: trailingAnchor)
])
