如何在UITableViewCell重新订购后更改标签的文本

Question

我有一个带有自定义单元格的UITableView。当我点击编辑时，TableView会进入编辑模式。我可以移动单元格并删除它们，并将结果保存到核心数据实体。核心数据中保留了单元格的新顺序，这一切都有效。

但是我希望在移动之后或点击“完成”之后，反映出单元格的新位置。无论标签被移动到什么位置，标签中的值始终是行+1。我如何重新申请

实现此目标的最佳方法是什么？

在此先感谢

- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath 
{ 
ProfileItems *profileItems = [ingredients objectAtIndex:fromIndexPath.row]; 
// NSLog(@"profileItems: %@", profileItems); 

[ingredients removeObjectAtIndex:fromIndexPath.row]; 
[ingredients insertObject:profileItems atIndex:toIndexPath.row]; 

NSInteger start = fromIndexPath.row; 
NSLog(@"start: %d", start); 

NSInteger end = toIndexPath.row; 
NSLog(@"end: %d", end); 

// Update Core Data to reflect the cell's new position in the TableView 
profileItems.profileItemsSongOrder = [NSNumber numberWithInteger:end + 1]; 

// This won't work becuase there is no cell referenced in here. Do I have to point to it again? If so how? 
cell.profileItemsSongNumberLabel.text = [NSString stringWithFormat:@"%@",profileItems.profileItemsSongOrder]; 
}

我解决了这个与......循环以下

for (int i = 0; i < numberOfRows; i++) 
    { 
     [[profileItemsNSMArray objectAtIndex:i] setValue:[NSNumber numberWithInt:i + 1] forKey:@"profileItemsSongOrder"]; 
    }
