Hey.

I am loading in data to a UITableView, from a custom UITableViewCell (own class and nib). It works great, until I try to access the indexPath.row/[indexPath.row]. I'll post my code first, it will probably be easier for you to understand what I mean then.

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

    static NSString *CellIdentifier = @"CustomCell";


    CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil){
        NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];

        for (id currentObject in topLevelObjects){
            if ([currentObject isKindOfClass:[CustomCell class]]){
                cell = (CustomCell *) currentObject;
                break;
            }
        }
    }
    NSLog(@"%@", indexPath.row);
    // Configure the cell...
    NSUInteger row = indexPath.row;
    cell.titleLabel.text = [postsArrayTitle objectAtIndex:indexPath.row];
    cell.dateLabel.text = [postsArrayDate objectAtIndex:indexPath.row];
    cell.cellImage.image = [UIImage imageWithContentsOfFile:[postsArrayImg objectAtIndex:indexPath.row]];

    NSLog(@"%@", indexPath.row);

    return cell;
}

The odd thing is, it does work when it loads in the first three cells (they are 125px high), but crashes when I try to scroll down.

The indexPath is always avaliable, but not the indexPath.row, and I have no idea why it isn't!

Please help me.. Thanks.
