从表格视图单元格中的 UITextfield 获取和设置值

Question

我在单元格中有 4 个文本字段。当我在其中一些输入值时，我会调用一个方法，然后需要在另一个文本字段中显示一些数据。我有 3 行单元格。目前只有最后一行的值是正确的。

    { 
        cell.selectionStyle=UITableViewCellSelectionStyleNone;

        cell.qntityTxt.tag=indexPath.row;

        [cell.qntityTxt addTarget:self action:@selector(totalCalc:) forControlEvents:UIControlEventEditingDidEnd];


        return cell;
    }

    - (void)totalCalc:(UITextField*)txtfield
    {
        int total,price,qty;
          NSLog(@"Tag value %ld",(long)txtfield.tag);
            price=[cell.priceTxt.text intValue];
            qty=[cell.qntityTxt.text  intValue];
            total=price*qty;

            Total=[NSString stringWithFormat:@"%d",total];
        cell.totlTxt.text=Total;

        [_addPdtTblVw reloadData];

    }

这和你评论的一样！！

    (void)totalCalc:(UITextField*)txtfield { 
    int total,price,qty;
     NSLog(@"Tag value %ld",(long)txtfield.tag); 
    for (int i=0; i < 3; i++){ 
    NSIndexPath indexPath = [NSIndexPath indexPathForRow: i inSection: 0];
    cell = [_addPdtTblVw cellForRowAtIndexPath:indexPath];
    UITextField *TextProduct= (UITextField)[cell.contentView viewWithTag:8];
    UITextField *TextPrice= (UITextField)[cell.contentView viewWithTag:9];
    UITextField *TextQuantity= (UITextField)[cell.contentView viewWithTag:10];
    UITextField *TextTotal= (UITextField)[cell.contentView viewWithTag:11];
    price=[TextPrice.text intValue];
    qty=[TextQuantity.text intValue];
    total=price*qty;
    Total=[NSString stringWithFormat:@"%d",total];
    cell.totlTxt.text=Total; 
    }
    [_addPdtTblVw reloadData];
    }
