    UILabel* txtLbl                     = (UILabel *) [cell.contentView viewWithTag:101];
    txtLbl.text                      =   [menuArray objectAtIndex:indexPath.row];

    return cell;
}

不要将标签命名为textLabel它默认使用..并且不要在(cell == nil)内设置子视图的值因为tableview重用了单元格。始终(cell == nil)阻止未调用..

UITableViewCell textLabel颜色不变
