    NotifyCell  *cell;
    for (id currentObject in topLevelObjects)
    {
        if ([currentObject isKindOfClass:[NotifyCell  class]])

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier1 = @"Cell1";
    static NSString *CellIdentifier2 = @"Cell2";
    static NSString *CellIdentifier3 = @"Cell3";

    self.productCell=(ProductCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
    self.notifyCell = (NotifyCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
    self.ratingCell =(RatingCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier3];

    if (productCell == nil) productCell = [self getProductCell];
    if (notifyCell == nil) notifyCell = [self getNotifyCell];
    if (ratingCell == nil) ratingCell = [self getRatingCell];

    switch (indexPath.section) {
        case 0:
        self.productCell.lblName.text=[productTitleArray objectAtIndex:indexPath.row];
        return productCell;
        break;
        case 1:
        self.productCell.lblName.text=[invoiceTitleArray objectAtIndex:indexPath.row];
        return productCell;
        break;
        case 2:
        self.productCell.lblName.text=[warrantyTitleArray objectAtIndex:indexPath.row];
        return productCell;
        break;
        case 3:
        self.productCell.lblName.text=@"Description";
        return productCell;
        break;

A few things here.

1 ) in each of the XIB files that host your table view cells, make certain you've set the identifier on them to match what you're using in your "cellForRowAtIndexPath" method. E.G. "@"Cell3" for RatingCells.

2) You need to register the cell reuse identifier for the object you're loading from a XIB.

For example:

UINib * nib = [UINib nibWithNibName: @"RatingCell" bundle: nil];
if(nib)
{
    [tableView registerNib: nib forCellReuseIdentifier:@"Cell3"];
}

You probably need to do this before you start calling "cellForRowAtIndexPath" (at least that's what I do). Perhaps you could send the "tableView" parameter in to your various "get*Cell" methods.
