iphone - 如何处理和检测iPhone中的tableviewcell的多个按钮

Question

我想更改 tableviewcell 的加号和减号按钮单击上的项目按钮值。这是我的行索引方法代码的表格 View 单元格。

static NSString *CellIdentifier = @"Cell";

            CustomCell *cell = [menuTableView dequeueReusableCellWithIdentifier:CellIdentifier];
            if (cell == nil) {
                cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
            }

            UIButton *minusBtn = [UIButton buttonWithType:UIButtonTypeCustom];
            minusBtn.frame= CGRectMake(400, 5,30,30);
            minusBtn.tag = indexPath.row;
            [minusBtn setImage:[UIImage imageNamed:@"removeButan.png"] forState:UIControlStateNormal];
            [minusBtn addTarget:self action:@selector(minusAction:) forControlEvents:UIControlEventTouchUpInside];

            UIButton *plusBtn = [UIButton buttonWithType:UIButtonTypeCustom];
            plusBtn.frame= CGRectMake(500, 5,30,30);
            plusBtn.tag = indexPath.row;
            [plusBtn setImage:[UIImage imageNamed:@"Addbutton.png"] forState:UIControlStateNormal];
            [plusBtn addTarget:self action:@selector(plusAction:) forControlEvents:UIControlEventTouchUpInside];    

            UIButton *itemBtn = [UIButton buttonWithType:UIButtonTypeCustom];
            itemBtn.frame= CGRectMake(450, 5,30,30);
            itemBtn.tag = indexPath.row;
            [itemBtn setBackgroundImage:[UIImage imageNamed:@"number_butan_1.png"] forState:UIControlStateNormal];
            [itemBtn setTitle:totalItem forState:UIControlStateNormal];
            [itemBtn setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

            UIButton *addToCart = [UIButton buttonWithType:UIButtonTypeCustom];
            addToCart.frame= CGRectMake(580,5,30,30);
            addToCart.tag = indexPath.row;
            addToCart.font = [UIFont systemFontOfSize:14];
            [addToCart setImage:[UIImage imageNamed:@"cart.png"] forState:UIControlStateNormal];
            [addToCart addTarget:self action:@selector(addToCartAction:) forControlEvents:UIControlEventTouchUpInside]; 

            UIButton *infoBtn = [UIButton buttonWithType:UIButtonTypeCustom];
            infoBtn.frame= CGRectMake(630, 5,30,30);
            infoBtn.tag = indexPath.row;
            [infoBtn setImage:[UIImage imageNamed:@"info.png"] forState:UIControlStateNormal];
            [infoBtn addTarget:self action:@selector(displayDetailView:) forControlEvents:UIControlEventTouchUpInside];

            // lblTitle.text = [nameArray objectAtIndex:indexPath.row];
            cell.primaryLabel.text = [appDelegate.nameArray objectAtIndex:indexPath.row];
            cell.secondaryLabel.text = [appDelegate.sortDetailArray objectAtIndex:indexPath.row];
            cell.priceLabel.text = [appDelegate.rateArray objectAtIndex:indexPath.row];

            [cell.contentView addSubview:minusBtn];
            [cell.contentView addSubview:plusBtn];
            [cell.contentView addSubview:addToCart];
            [cell.contentView addSubview:itemBtn];
            [cell.contentView addSubview:infoBtn];

            return cell;
}


- (IBAction)plusAction:(id)sender{

   // Hat* obj = ((UIButton *)sender).tag;
   // NSNumber* hatId = obj.idValue;

    UITableViewCell *cell=(UITableViewCell*)[[sender superview] superview];
    UITableView *table=(UITableView*)[cell superview];
    NSIndexPath *path=[table indexPathForCell:cell];

    int value = [totalItem intValue];
    value++;

    totalItem = [NSString stringWithFormat:@"%d",value];
    NSLog([NSString stringWithFormat:@"%@",totalItem]);
    [menuTableView reloadData];

}

- (IBAction)minusAction:(id)sender{

    UIView *contentView = [sender superview];

    UITableViewCell *cell=(UITableViewCell*)[[contentView superview] superview];
    UITableView *table=(UITableView*)[cell superview];
    NSIndexPath *path=[table indexPathForCell:cell];

    NSUInteger buttonRow = [[menuTableView
                             indexPathForCell:cell] row];

    int value = [totalItem intValue];
    value--;

    totalItem = [NSString stringWithFormat:@"%d",value];
    NSLog([NSString stringWithFormat:@"%@",totalItem]);
    [menuTableView reloadData];

}

我正在尝试此操作，但不起作用。它更改了所有行值

您只有一个 TotalItem 实例。如果您有很多行并且想要单独存储每一行​​，则需要创建一个数组来存储每一行​​，然后在 cellForRow 方法中显示适当的值。
