在UIViewRepresentable CollectionView中为UICollectionViewCell使用SwiftUI视图(包装的UICollectionView)

struct CollectionViewWrapper: UIViewRepresentable {
    func makeUIView(context: Context) -> UICollectionView {
        let layout = UICollectionViewFlowLayout()
        let collectionView = UICollectionView(frame: .zero, collectionViewLayout: layout)
        // 设置UICollectionView的属性和代理等
        return collectionView
    }
    
    func updateUIView(_ uiView: UICollectionView, context: Context) {
        // 更新UICollectionView的内容
    }
}

struct CollectionViewWrapper: UIViewRepresentable {
    // ...

    func makeUIView(context: Context) -> UICollectionView {
        let layout = UICollectionViewFlowLayout()
        let collectionView = UICollectionView(frame: .zero, collectionViewLayout: layout)
        collectionView.register(MyCustomCell.self, forCellWithReuseIdentifier: "CustomCell")
        collectionView.dataSource = context.coordinator
        collectionView.delegate = context.coordinator
        return collectionView
    }
    
    func updateUIView(_ uiView: UICollectionView, context: Context) {
        // 更新UICollectionView的内容
        uiView.reloadData()
    }
    
    // ...
}

class Coordinator: NSObject, UICollectionViewDataSource, UICollectionViewDelegate {
    // 实现UICollectionViewDataSource和UICollectionViewDelegate的方法
}

struct CollectionViewWrapper: UIViewRepresentable {
    // ...
    
    func makeCoordinator() -> Coordinator {
        return Coordinator()
    }
    
    // ...
}

struct ContentView: View {
    var body: some View {
        CollectionViewWrapper()
            .frame(width: 300, height: 200)
    }
}
