static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

}
int getIndex = [sharedGameState.selectedValues indexOfObject:[NSNumber numberWithInt:indexPath.row]];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
if(getIndex<21)
{
    cell.accessoryType = UITableViewCellAccessoryCheckmark;

Reuse Cell ,

- (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];


        int getIndex = [sharedGameState.selectedValues indexOfObject:[NSNumber numberWithInt:indexPath.row]];
        [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
        if(getIndex<21)
        {
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
        }
        else
        {
            cell.accessoryType = UITableViewCellAccessoryNone;
        }
    } // END HERE
    cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
    return cell;
}
