Várias linhas personalizadas UITableView?

Eu tenho procurado muito, mas não encontrei nada útil relacionado a várias linhas personalizadas, eu preciso criar um tableView de configurações para o meu aplicativo, no qual eu preciso carregar as linhas de arquivos xib, como:

ROW 1 = >> XIB 1.
ROW 2 = >> XIB 2.
ROW 3 = >> XIB 3.
ROW 4 = >> XIB 4.

Meu código atual:

<code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell=nil;
    //We use CellType1 xib for certain rows
    if(indexPath.row==0){
        static NSString *CellIdentifier = @"ACell";
        cell =(ACell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if(cell==nil){
            NSArray *nib= [[NSBundle mainBundle] loadNibNamed:@"ACell" owner:self options:nil];
            cell = (ACell *)[nib objectAtIndex:0];
        }
        //Custom cell with whatever
        //[cell.customLabelA setText:@"myText"]
    }
    //We use CellType2 xib for other rows
    else{
        static NSString *CellIdentifier = @"BCell";
        cell =(BCell*) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if(cell==nil){
            NSArray *nib= [[NSBundle mainBundle] loadNibNamed:@"BCell" owner:self options:nil];
            cell = (BCell *)[nib objectAtIndex:0];
        }
        //Custom cell with whatever
        //[cell.customLabelB setText:@"myText"]
    }

    return cell;
}
</code>
