我在使用可区分数据源的 tableViewCell XiB 中使用 collectionView 时遇到问题。我想像男装和女装一样显示两个部分。我不知道如何迭代每个案例并相应地显示记录请检查下面的代码.传递tableView的索引路径并在collectionView中使用以显示基于行的部分。我不知道如何创建正确的数据源和快照。表视图控制器类：

public enum CategoriesSection{
    case first
}
class TableCollectionCell: UIViewController {

    @IBOutlet weak var tableView:UITableView!
    var categories:[Product] = []
    var mens1 :[Mens] = []
    var womens1:[Womens] = []
    var datasource:UITableViewDiffableDataSource<CategoriesSection,Product>!
    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.delegate = self
        tableView.dataSource = datasource
        tableView.register(UINib(nibName: String(describing: TableCell.self), bundle: .main), forCellReuseIdentifier: String(describing: TableCell.self))
    }
}
extension TableCollectionCell:UITableViewDelegate{
 
    func createDataSource(){
        datasource = UITableViewDiffableDataSource(tableView: tableView, cellProvider: { (tableview, indexPath, items) -> UITableViewCell? in
            guard let cell = tableview.dequeueReusableCell(withIdentifier: String(describing: TableCell.self)) as? TableCell else {return UITableViewCell()}
            cell.getData = self.categories[indexPath.row]
            return cell
        })
    }
    
    func createSnapshot(){
        var snapshot = NSDiffableDataSourceSnapshot<CategoriesSection,Product>()
        snapshot.appendSections([.first])
        snapshot.appendItems(categories)
        datasource.apply(snapshot, animatingDifferences: true, completion: nil)
        
    }
}

类别单元视图控制器

public enum tableCollection{
    case one
    case two
    case three
}
class CategoiresCell: UITableViewCell {
    @IBOutlet weak var name:UILabel!
    @IBOutlet weak var collectionView:UICollectionView!
    var mens1 :[Mens] = []
    var womens1:[Womens] = []
    var row = 0
    var datasource : UICollectionViewDiffableDataSource<tableCollection,String>?
    override func awakeFromNib() {
        super.awakeFromNib()
        collectionView.delegate = self
        collectionView.dataSource = datasource
        collectionView.register(UINib(nibName: String(describing: MensCell.self), bundle: .main), forCellWithReuseIdentifier: String(describing: MensCell.self))
        collectionView.register(UINib(nibName: String(describing: WomensCell.self), bundle: .main), forCellWithReuseIdentifier: String(describing: WomensCell.self))
       
    }
    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

    }
    
}
extension CategoiresCell:UICollectionViewDelegate{
    
       func createDataSource(){
        datasource = UICollectionViewDiffableDataSource(collectionView: collectionView, cellProvider: { (collectionview, indexPath,items) -> UICollectionViewCell? in
            switch self.row{
                case 0:
                    guard let cell = collectionview.dequeueReusableCell(withReuseIdentifier: String(describing: MensCell.self), for: indexPath) as? MensCell else {return UICollectionViewCell()}
                    cell.getData = self.mens1[indexPath.item]
                    return cell
            case 1:
                guard let cell = collectionview.dequeueReusableCell(withReuseIdentifier: String(describing: WomensCell.self), for: indexPath) as? WomensCell else {return UICollectionViewCell()}
                cell.getData = self.womens1[indexPath.item]
                return cell
            default:break
            }
            return UICollectionViewCell()
        })
       
       }
       
       func createSnapshot(){
           var snapshot = NSDiffableDataSourceSnapshot<tableCollection,String>()
//           snapshot.appendSections([.first])
//           snapshot.appendItems(products)
//           datasource.apply(snapshot, animatingDifferences: true, completion: nil)
//
       }
}
