ios – 如何在UITableViewCell中获取UIButton的indexPath？

参见英文答案 > How to know the UITableview row number????????????????????????????????????10个
我有一个包含多个单元格的UITableview.在每个单元格上,我根据一些数组计数动态添加按钮.所以,当我点击一个按钮时,我就可以获得按钮的标签值.但是如何获取该单元格的indexPath？

这是我在-cellForRowAtIndexPath中的代码：

UIView *view=(UIView*)[cell.contentView viewWithTag:indexPath.row+444];

   UIImageView *img=(UIImageView*)[cell.contentView viewWithTag:indexPath.row+999];
   img.image=[UIImage imageNamed:@"BHCS_empty.png"];

   if(integer!=50)
   {
        NSInteger y_axis=0;
        NSArray *Arr=[tableSubCategoryArr objectAtIndex:indexPath.row];
        img.image=[UIImage imageNamed:@"BHCS_selected.png"];

        view.Frame= CGRectMake(0,50,281,integer-50);
        for (int i=0; i<[Arr count]; i++)
        {
            NSLog(@"arr %@",[Arr objectAtIndex:i]);
            UIButton *Btn=[UIButton buttonWithType: UIButtonTypeCustom];
            Btn.frame=CGRectMake(0,y_axis,44);
            [Btn setImage:[UIImage imageNamed:@"BHCS_panel.png"] forState:UIControlStateNormal];
            [Btn addTarget:self action:@selector(subCategoryBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
            [Btn setTag:i+100];
            [view addSubview:Btn];


            UILabel *nameLbl=[[UILabel alloc]initWithFrame:CGRectMake(20,248,44)];
            nameLbl.text = [[Arr objectAtIndex:i]objectForKey:@"SubCategoryName"];
            nameLbl.textColor = [UIColor whiteColor];
            nameLbl.backgroundColor=[UIColor clearColor];
            panelTableView.separatorColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"BHCS_panel_div1.png"]];
            nameLbl.font = [UIFont fontWithName:@"Helvetica" size:12.0f];
            [view addSubview:nameLbl];

            y_axis=y_axis+44+1.3f;
        }
    }

CGPoint buttonPosition = [sender convertPoint:CGPointZero toView:self.tableView];
 NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
