Question

I have a weird problem (at least in my opinion). When I add a UISwitch to my table view, the switch changes cell automatically when the user scrolls the table view. Below is the code on how I create the UISwitch for the tableview.

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

        //NSLog(@"This is what we are looking for %@    %@", checkUsername, checkPassword);
        // Configure the cell...
    NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];
    NSArray *array =[dictionary objectForKey:@"Settings"];
    NSString * cellValue = [array objectAtIndex:indexPath.row];

    static NSString *CellIdentifier = @"Cell";
    NSUInteger section = [indexPath section];
    NSUInteger row = [indexPath row];
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    cell.accessoryView = nil;


    if (!cell) {

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
        cell.textLabel.adjustsFontSizeToFitWidth = YES;
            //switcher.on = [[NSUserDefaults standardUserDefaults]boolForKey:@"Settings"];

        if (section == 1)
        {

            UISwitch *switchView = [[UISwitch alloc] init];
            cell.accessoryView = switchView;
            [switchView setOn:YES animated:NO];
            [switchView setTag:[indexPath row]];
            [switchView addTarget:self action:@selector(switchWasChangedFromEnabled:) forControlEvents:UIControlEventValueChanged];
                //[self.tableView reloadData];
            [switchView release];
        }

    }
    return cell;
}

Can someone please let me know why the switches keep moving out of the designated cells and also a possible remedy.

Justin Gallagher suggested this:

It’s happening because you’re cacheing your cells and reusing them. Sometimes the cell with the switch is getting reused in another place. Try setting a different identifier for the cell with the switch.

But can someone tell me how I can set different identifier for each cell?

Cheers,
