Question

I have a UITableView that was working fine until I added sections to it – now the data from the first cell repeats throughout all the other cells. When I remove the sections line below, everything goes back to normal.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    NSInteger sections = self.objects.count;

    return sections;
}

Any ideas on what could be going on here? My data source is Core Data, by the way.

EDIT

For numberOfRows I’m returning 1.

Here’s how I’m implementing the cells:

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

Item *p = [[[ItemStore defaultStore] allItems]
                                objectAtIndex:[indexPath row]];

    ItemCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ItemCell"];

    [cell setController:self];
    [cell setTableView:tableView];

    [[cell nameLabel] setText:[p itemName]];
    [[cell serialNumberLabel] setText:[p serialNumber]];
    [[cell valueLabel] setText:[NSString stringWithFormat:@"$%d", [p valueInDollars]]];

    [[cell thumbnailView] setImage:[p thumbnail]];


return cell;
}

Answer 1

You are probably using

cell.textlabel.text = [self.objects objectAtIndex: indexPath.row];

in your cellForRowAtIndexPath method.

This would work in a table view with one section, as the row number will increase each time.
However, if you have multiple sections, the row number is reset back to 0 for the first row in each section.
Therefore, indexPath.row will always return 0 in the cellforRowAtIndexPath method, hence you are getting the first object each time.
You will have to do a check for which section you are in, or even use the section number as a way of getting the correct object from the array.

EDIT: Looking at the code you’ve posted, this is exactly what’s happening! Look into identifying which section you’re in, and filling it appropriately.
