Question

Im working with the CoreDataBooks example project from Apple and I want to have a custom cell at indexPath 0 in my tableview and then have my core data fetched results start from index 1.

I have tried some different solutions but can’t get it working, if you have any ideas it would due appreciated thanks.

If you want to know what I have tried and failed let me know. What I want to achieve seems simple, just start the fetched results at cell 1 rather than 0.

Edit 2:

All my UITableViewDataSource and configureGuestCell code:

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
    {    
        if (indexPath.row == 0) 
        {
            static NSString *CellIdentifier = @"statsCell";

            GuestStatsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
            if (cell == nil) 
            {
                cell = [[GuestStatsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
            }

            //Configure the cell.
            [self configureStatsCell:cell];

            return cell;
        }
        if (indexPath.row > 0)
        {
            static NSString *CellIdentifier = @"guestCell";

            customGuestCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
            if (cell == nil) 
            {
                cell = [[customGuestCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
            }

            // Configure the cell.
            [self configureGuestCell:cell atIndexPath:indexPath];

            return cell;
        }
    }


- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    int cellHeight;

    if (indexPath.row == 0) 
    {
        cellHeight = 240;
    }
    else
    {
        cellHeight = 44;
    }

    return cellHeight;
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{
    return [[fetchedResultsController sections] count];
}


// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{
    id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section];
    return [sectionInfo numberOfObjects];
}

- (void)configureGuestCell:(customGuestCell *)cell atIndexPath:(NSIndexPath *)indexPath 
{
    //Configure the cell to show the Guests first and last name and other details
    GuestInfo *guest = [fetchedResultsController objectAtIndexPath:indexPath];

    cell.guestNameLbl.text = [NSString stringWithFormat:@"%@ %@", guest.firstName, guest.lastName];

}


- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath 
{

    if (editingStyle == UITableViewCellEditingStyleDelete) 
    {

        // Delete the managed object.
        NSManagedObjectContext *context = [fetchedResultsController managedObjectContext];
        [context deleteObject:[fetchedResultsController objectAtIndexPath:indexPath]];

        NSError *error;
        if (![context save:&error]) 
        {
            // Update to handle the error appropriately.
            NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
            exit(-1);  // Fail
        }
    }   
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
    // Create and push a detail view controller.
    guestListDetailViewController *detailViewController = [[guestListDetailViewController alloc] initWithStyle:UITableViewStyleGrouped];
    GuestInfo *selectedGuest = (GuestInfo *)[[self fetchedResultsController] objectAtIndexPath:indexPath];
    // Pass the selected book to the new view controller.
    detailViewController.guest = selectedGuest;
    [self.navigationController pushViewController:detailViewController animated:YES];
}

Answer 1

Fixed code:

// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{
    id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section];
    return [sectionInfo numberOfObjects] +1;
}

- (void)configureGuestCell:(customGuestCell *)cell atIndexPath:(NSIndexPath *)indexPath 
{
    NSIndexPath *path = [NSIndexPath indexPathForRow:(indexPath.row - 1) inSection:indexPath.section]
    //Configure the cell to show the Guests first and last name and other details
    GuestInfo *guest = [fetchedResultsController objectAtIndexPath:path];

    cell.guestNameLbl.text = [NSString stringWithFormat:@"%@ %@", guest.firstName, guest.lastName];

}

Small explanation:
you should return a one row more in numberOfRowsInSection, but, to prevent errors, row number should be decremented before calling [NSFetchedResultsController objectAtIndexPath].
