Answer 1

To answer your first question, you may as well return nil as you have no good value to return. If it ever hits this case, an exception will be thrown; as it is now, it's likely to give you an EXC_BAD_ACCESS somewhere inside the framework code.

To answer your second question, each type of cell should have a unique reuseIdentifier. For example, all the CellA's could have a reuseIdentifier of @"CellA". Then you would reuse them exactly as you would in the case that all the cells were the same: when you need a CellA call [tableView dequeueReusableCellWithIdentifier:@"CellA"], when you need a CellB call [tableView dequeueReusableCellWithIdentifier:@"CellB"], and so on. For example,

    case 0:
        if (indexPath.row == 0) {
            CellA *cell = [tableView dequeueReusableCellWithIdentifier:@"CellA"];
            if (!cell) {
                cell = [[[CellA alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellA"] autorelease];
            }
            // configure cell
            return cell;
        }
        else if (indexPath.row == 1) {
            CellB *cell = [tableView dequeueReusableCellWithIdentifier:@"CellB"];
            if (!cell) {
                cell = [[[CellB alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellB"] autorelease];
            }
            // configure cell
            return cell;
        }
        break;
    case 1:
        if (indexPath.row == 0) {
            CellC *cell = [tableView dequeueReusableCellWithIdentifier:@"CellC"];
            if (!cell) {
                cell = [[[CellC alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellC"] autorelease];
            }
            // configure cell
            return cell;
        }
        break;
