UItableView reuses the cell in every scroll so using condition as per accessory type is not a good practice. You can Create an NSMutableArray with selected items and Check as per the Condition below.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }
    if ([selected containsIndex:indexPath.row]) {
        [cell setAccessoryType:UITableViewCellAccessoryCheckmark];
    } else {
        [cell setAccessoryType:UITableViewCellAccessoryNone];
    }
    // Do the rest of your code
    return cell;
} 

in didSelectrowAtindexpath method you can Add and remove the Selected items.
