UICollectionViewCell中的SwiftUI视图

class MyCollectionViewCell: UICollectionViewCell {
    var contentView: UIView!
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        setupContentView()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
        setupContentView()
    }
    
    private func setupContentView() {
        // 创建一个UIHostingController，并将其视图作为contentView的子视图
        let hostingController = UIHostingController(rootView: MySwiftUIView())
        contentView = hostingController.view
        contentView.frame = bounds
        contentView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        addSubview(contentView)
    }
}

import SwiftUI

struct MySwiftUIView: View {
    var body: some View {
        Text("Hello, SwiftUI!")
            .font(.title)
            .foregroundColor(.blue)
    }
}

collectionView.register(MyCollectionViewCell.self, forCellWithReuseIdentifier: "MyCell")

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "MyCell", for: indexPath) as! MyCollectionViewCell
    // 可以在此处对cell进行配置，如设置数据等
    return cell
}
