如何在 cellForRowAtIndexPath 方法中下载图像？

我的代码如下

Cell_ClubOffer *cell = [tableFavouriteDealsAndClubs dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {
        cell = [[Cell_ClubOffer alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }

        if (indexPath.section < [array_favouriteClubs count]){

            //show clubs here

            ClubDAO *ob = (ClubDAO*)[array_favouriteClubs objectAtIndex:indexPath.section];

            NSLog(@"MY IMAGE URL IS %@", ob.logopath); //is Logo Path

           //Use other ob values on Cell and return it


           return cell;


        }else{

            //show deals here

            int section = (indexPath.section-[array_favouriteClubs count]);

            NSLog(@"SECTION IS %d", (indexPath.section-[array_favouriteClubs count]));

            NSLog(@"COUNT IS OBJECT IS %d", [array_favouriteDeals count]);


            DealsDAO *ob = (DealsDAO*)[array_favouriteDeals objectAtIndex: section];
            NSLog(@"MY IMAGE URL IS %@", ob.logopath); //is Logo Path

           //Use other ob values on Cell and return it

           return cell;

     }

现在，我有两个数组，

* array_favouriteDeals* * array_favouriteClubs*

所以，有两个数组包含，不同的对象，作为 indexOfFirst 结束，我只是使用*(indexPath.section-[array_favouriteClubs count]);*作为下一个索引。

如何下载这种场景的图像？

谢谢
