我在 stackoverflow 上搜索了有关如何执行此操作的提示，并且 I found this question here但这并没有解决我的问题，我想要同样的东西(每 5 行添加一个广告 after)，我尝试了那里提到的解决方案，但我得到的是第一行被广告取代，如第5等，我的正常内容正在被广告取代。 所以我想实现这个:

row 0 = normal content
row 1 = normal content
row 2 = normal content
row 3 = normal content
row 4 = normal content
row 5 = ad
row 6 = normal content
...

这是我尝试过的:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        if (indexPath.row % 5 == 0 && indexPath.row != 0) {
            if let cellBanner = tableView.dequeueReusableCell(withIdentifier: "cellBanner", for: indexPath) as? BannerCell {

                return cellBanner
            } else {
                return UITableViewCell()
            }
        } else {
            if let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as? AnuncioCell {
                if AnunciosService.instance.anuncios.count >= indexPath.row {
                    let anuncio = AnunciosService.instance.anuncios[indexPath.row]
                    let rowsToLoadFromBottom = 5;
                    let rowsLoaded = AnunciosService.instance.anuncios.count

                    if (!self.fetchingMore && (indexPath.row - (indexPath.row / 5) >= (rowsLoaded - rowsToLoadFromBottom))) {
                        let totalRows = AnunciosService.instance.anunciosCount
                        let remainingAnunciosToLoad = totalRows - rowsLoaded;
                        if (remainingAnunciosToLoad > 0) {
                            self.loadMoreAnuncios()
                        }
                    }

                    cell.configureCell(anuncio: anuncio)
                    let checkValue = Double(anuncio.user.nota)!
                    if checkValue < 1.0 {
                        cell.notaView.isHidden = true
                    }else{
                        cell.notaView.isHidden = false
                    }
                    if anuncio.destaque {
                        cell.destaque.isHidden = false
                    } else {
                        cell.destaque.isHidden = true
                    }
                    if anuncio.status == 0 {
                        if cell.imgAnuncio.image != nil{
                            Noir(originalImage: cell.imgAnuncio)
                        }
                        cell.sold_out.isHidden = false
                        cell.selectionStyle = .none
                        cell.isUserInteractionEnabled = false;
                    } else {
                        cell.sold_out.isHidden = true
                        cell.isUserInteractionEnabled = true;
                        cell.selectionStyle = .default
                    }

                }

                return cell
            } else {
                return UITableViewCell()
            }
        }

    }

编号的行数:

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if AnunciosService.instance.anuncios.count == 0 {
            return 0
        }
        return AnunciosService.instance.anuncios.count + BannersService.instance.banners.count
    }

最佳答案

我做错了，对于那些想知道我是如何解决它的人:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let index = indexPath.row + 1
        if (index % 6 == 0 && indexPath.row != 0 && index/6 <= BannersService.instance.banners.count) {
            let cellBanner = tableView.dequeueReusableCell(withIdentifier: "cellBanner", for: indexPath) as! BannerCell

            return cellBanner
        } else {
            let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! AnuncioCell
            let index = indexPath.row - (indexPath.row / 6)
            if AnunciosService.instance.anuncios.count > index {
                let anuncio = AnunciosService.instance.anuncios[index]
                let rowsToLoadFromBottom = 5;
                let rowsLoaded = AnunciosService.instance.anuncios.count

                if (!self.fetchingMore && (index >= (rowsLoaded - rowsToLoadFromBottom))) {
                    let totalRows = AnunciosService.instance.anunciosCount
                    let remainingAnunciosToLoad = totalRows - rowsLoaded;
                    if (remainingAnunciosToLoad > 0) {
                        self.loadMoreAnuncios()
                    }
                }

                cell.configureCell(anuncio: anuncio)
                let checkValue = Double(anuncio.user.nota)!
                if checkValue < 1.0 {
                    cell.notaView.isHidden = true
                }else{
                    cell.notaView.isHidden = false
                }
                if anuncio.destaque {
                    cell.destaque.isHidden = false
                } else {
                    cell.destaque.isHidden = true
                }
                if anuncio.status == 0 {
                    if cell.imgAnuncio.image != nil {
                        Noir(originalImage: cell.imgAnuncio)
                    }
                    cell.sold_out.isHidden = false
                    cell.selectionStyle = .none
                    cell.isUserInteractionEnabled = false;
                } else {
                    cell.sold_out.isHidden = true
                    cell.isUserInteractionEnabled = true;
                    cell.selectionStyle = .default
                }
            }

            return cell
        }

    }
