具有图像数组的UICollectionView将其设置正确

import UIKit

class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
    var imageArray = [UIImage]() // 图像数组
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let layout = UICollectionViewFlowLayout()
        let collectionView = UICollectionView(frame: view.bounds, collectionViewLayout: layout)
        collectionView.dataSource = self
        collectionView.delegate = self
        collectionView.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
        view.addSubview(collectionView)
        
        // 加载图像数据
        imageArray.append(UIImage(named: "image1")!)
        imageArray.append(UIImage(named: "image2")!)
        // ...
    }
    
    func numberOfSections(in collectionView: UICollectionView) -> Int {
        return 1 // 单个分区
    }
    
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return imageArray.count // 图像数组的项目数
    }
    
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath)
        
        // 设置图像视图
        let imageView = UIImageView(frame: cell.contentView.bounds)
        imageView.image = imageArray[indexPath.item]
        cell.contentView.addSubview(imageView)
        
        return cell
    }
}
