Question

我制作了两张桌子ProductTable（tag = 1）＆amp;卖表（tag = 2）

ProductTable正确显示数据但是销售表并没有显示任何细胞数量。

请告诉我为什么会这样？

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

    if (tableView.tag==1 )
    {

        return ProductImages.count;
    }

    else
    {

        return MostProductImages.count;
    }

}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{



if (tableView.tag==1 )
    {
        ProductTableViewCell *cell= [_ProductTableView dequeueReusableCellWithIdentifier:@"SimpleTableView"];

    if ([[ProductImages objectAtIndex:indexPath.row] isEqual: [NSNull null] ])
            {
                cell.product_image.image= [UIImage imageNamed:@"ic_launcher.png"];
            }

            else

                cell.product_image.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[Productaddurl stringByAppendingPathComponent:[ProductImages objectAtIndex:indexPath.row]]]]];

    cell.product_name.text= [Product_Name objectAtIndex:indexPath.row];


    cell.product_mp.text= [MP objectAtIndex:indexPath.row];
    cell.product_sp.text= [SP objectAtIndex:indexPath.row];
    cell.product_image.transform=CGAffineTransformMakeRotation(M_PI_2);
    cell.product_name.transform= CGAffineTransformMakeRotation(M_PI_2);
    cell.product_mp.transform= CGAffineTransformMakeRotation(M_PI_2);
    cell.product_sp.transform= CGAffineTransformMakeRotation(M_PI_2);
    cell.heartButton.transform= CGAffineTransformMakeRotation(M_PI_2);
        cell.rup.transform = CGAffineTransformMakeRotation(M_PI_2);
    [cell.layer setBorderWidth: 0.1];
        [cell.layer setCornerRadius:10.0f];
        [cell.layer setMasksToBounds:YES];
        [cell.layer setBorderColor:[[UIColor grayColor] CGColor]];
    [self performSelectorOnMainThread:@selector(updateTable) withObject:nil waitUntilDone:NO];

        return cell;


    }

       if (tableView.tag==2)
        {

        SellingTableViewCell *cell1= [_SellingTableView dequeueReusableCellWithIdentifier:@"SimpleTableCell"];

    if ([[MostProductImages objectAtIndex:indexPath.row] isEqual: [NSNull null] ])

    {
        cell1.selling_image.image= [UIImage imageNamed:@"ic_launcher.png"];

    }
    else
 cell1.selling_image.image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[Productaddurl stringByAppendingPathComponent:[MostProductImages objectAtIndex:indexPath.row]]]]];

                 cell1.selling_name.text= [MostProduct_Name objectAtIndex:indexPath.row];

            //NSLog(@"%@", [MostProduct_Name objectAtIndex:indexPath.row]);

            cell1.selling_mp.text= [MostMP objectAtIndex:indexPath.row];
            cell1.selling_sp.text= [MostSP objectAtIndex:indexPath.row];

            cell1.selling_name.transform= CGAffineTransformMakeRotation(M_PI_2);
            cell1.selling_mp.transform= CGAffineTransformMakeRotation(M_PI_2);
            cell1.selling_sp.transform= CGAffineTransformMakeRotation(M_PI_2);
            cell1.heartButton.transform= CGAffineTransformMakeRotation(M_PI_2);
            cell1.selling_image.transform=CGAffineTransformMakeRotation(M_PI_2);

            cell1.selling_name.numberOfLines = 2;

            [cell1.layer setBorderWidth: 0.1];
            [cell1.layer setCornerRadius:10.0f];
            [cell1.layer setMasksToBounds:YES];
            [cell1.layer setBorderColor:[[UIColor grayColor] CGColor]];
                 [cell1.contentView setAlpha:0];
                 [cell1 setUserInteractionEnabled:NO];

                [self performSelectorOnMainThread:@selector(updateTable) withObject:nil waitUntilDone:NO];

            return cell1;
        }

     return nil;
}

确保MostProductImages数组中包含一些值。
比较两个表的每个属性。您是否正确引用了viewController.swift文件中的两个表格。您是否正确设置了两个表的委托和dataSource？您是否正确设置了两个表的标签？

希望这会有所帮助：）

两个表视图。一个获取数据＆amp;其他没有显示数据
