Iphone Don'；不允许将单元格移动到另一部分

如何禁用用户可以将单元格移动到其他分区？我不想每次都显示警报；）

谢谢：D

实现targetIndexPathFormovfromRowAtIndexPath委托方法：

- (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;
}

这确实对我有帮助。非常感谢。
