    You need to check the cell is already selected or not in the cellForRowAtIndexPath method. This issue is happening because tableView re-uses the cells. Please write the below code in your cellForRowAtIndexPath method, it'll solve the issue.

    NSNumber *rowNsNum = [NSNumber numberWithUnsignedInt:indexPath.row];
    if ( [selectedCells containsObject:rowNsNum]  )
    {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
