Different cells CollectionView rxswift

Question

Good evening. Tell me please I need to make such an implementation Have: CollectionView Rxswift The maximum number of cells is 6 If there are less than 6 elements in a certain array, then the first cells are filled with one type (by the number of elements in the array), and the rest with other cells.

collectionView.register(UINib(nibName: "PhotoCollectionCell", bundle: nil), forCellWithReuseIdentifier: "PhotoCell")
collectionView.register(UINib(nibName: "EmptyCollectionCell", bundle: nil), forCellWithReuseIdentifier: "EmptyCell")

Please check collectionView.rx.items in UICollectionView+Rx.swift from RxCocoa Here is the example from code itselft

   let items = Observable.just([
             1,
             2,
             3
         ])

         items
         .bind(to: collectionView.rx.items) { (collectionView, row, element) in
            let indexPath = IndexPath(row: row, section: 0)
            let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as! NumberCell
             cell.value?.text = "\(element) @ \(row)"
             return cell
         }
         .disposed(by: disposeBag)

You can dequeue whatever cell you want based on the index of the row or type of the data, just like the way we did in DataSource

This doesn't work for me, why? – paprika Aug 27 '22 at 18:25 — paprika, Aug 27 '22 at 18:25

You need to import RxDataSources in case you want different cell type.

        // TableView Cell Nib Register
        tableView.register(R.nib.meChatCell)
        tableView.register(R.nib.otherChatCell)

        vm.output.chats
        .bind(to: tableView.rx.items){(tv, row, item) -> UITableViewCell in

            if item.userId == 0 {
                let cellIdentifier = R.reuseIdentifier.meChatCell.identifier
                let cell = tv.dequeueReusableCell(withIdentifier: cellIdentifier, for: IndexPath.init(row: row, section: 0)) as! MeChatCell
                cell.vm = item
                return cell
            } else {
                let cellIdentifier = R.reuseIdentifier.otherChatCell.identifier
                let cell = tv.dequeueReusableCell(withIdentifier: cellIdentifier, for: IndexPath.init(row: row, section: 0)) as! OtherChatCell
                cell.vm = item
                return cell
            }

        }.disposed(by: disposeBag)
}
