Question

i have a tableView with a custom cell, my first cell is different with the others cells. ( it contain a small image and a label). I am doing like this :

#

pragma mark - tableView data source methods
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{


    SuggestionCarteCell *cell = (SuggestionCarteCell *)[tableView dequeueReusableCellWithIdentifier:@"carteCell"];
    if (cell == nil) {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"SuggestionCarteCell" owner:nil options:nil] ;
        cell = [nib objectAtIndex:0];
    }

    if (indexPath.row == 0) {
        // crer l'image

        NSLog(@" je suis dans row 0");
        UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(21, 9, 13, 26)];
        imageView.image = [UIImage imageNamed:@"iconeLocation"];
        [cell addSubview:imageView];
        cell.labelRegion.frame = CGRectMake(21+13+10, cell.labelRegion.frame.origin.y,cell.labelRegion.frame.size.width , cell.labelRegion.frame.size.height);
        cell.labelRegion.text = [NSString stringWithFormat:@"A proximité,"];

    }
    else{
    Region *region = [Region new];
    region  =(Region *) [arrayRegion objectAtIndex:indexPath.row];
    cell.labelRegion.text =region.nomRegion;


    }
    return cell;
}

in the first time it’s good, but when i scroll my first cell ( the small image added) appear in the other rows. What i am doing wrong ? thanks

You have two types of cell but only one reuse identifier.

Two options:

• Make sure that when your cell is reused it resets its state to a default, empty state. There’s a prepareForReuse method for this purpose
• Define two different cells, each with their own, unique reuse identifier. That way your first, different cell will not get reused later on
