//某一行是否可以移动- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPatt{    return NO;}

//确认移动- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{    if(sourceIndexPath.section == destinationIndexPath.section){        //获取要移动元素所在的组（子数组）        NSMutableArray *subArray = [_dataArray objectAtIndex:sourceIndexPath.section];        //获得要移动的对象        DataItem *item = [subArray objectAtIndex:sourceIndexPath.row];        //删除        [subArray removeObject:item];        //将他插入到新位置        [subArray insertObject:item atIndex:destinationIndexPath.row];          }else{        //获得要移动的对象        NSMutableArray *subArray = [_dataArray objectAtIndex:sourceIndexPath.section];        DataItem *item = [subArray objectAtIndex:sourceIndexPath.row];        [subArray removeObject:item];        //获得目标数组        NSMutableArray *destArray = [_dataArray objectAtIndex:destinationIndexPath.section];        //插入新元素        [destArray insertObject:item atIndex:destinationIndexPath.row];            }}
