实现 targetIndexPathForMoveFromRowAtIndexPath 委托(delegate)方法:

- (NSIndexPath *)tableView:(UITableView *)tableView 
    targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath 
    toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath
{
    if (proposedDestinationIndexPath.section != sourceIndexPath.section)
    {
        //keep cell where it was...
        return sourceIndexPath;
    }

    //ok to move cell to proposed path...
    return proposedDestinationIndexPath;
}
