Question

Why this code works fine:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        cell.textLabel.text = [NSString stringWithFormat:@"cell%i%i", indexPath.section, indexPath.row];
    }    
    return cell;
}

As far as I understood cell identifiers, this code should work correctly only if I move cell.textLabel.text = ... line out of if-statement. In other words, why labels have correct texts???

Answer 1

Try creating more cells than you can see on your screen and as soon as they get dequeued they will no longer have the text you expect…

It will basically be okay for 5 or so rows you see on the screen but as soon as you start scrolling you’ll be seeing some “interesting” stuff 🙂
