Question

我能够将单个图像转换为UITableViewCell。这是我需要的任务是将两个图像放入UITableViewCell。我在下面粘贴的代码是用来解析一个图像。建议我对Get 2 images进行更改。

 jsonDict = [jsonArr objectAtIndex:indexPath.row];
NSLog(@"imagess%@",jsonDict);
cell.textLabel.text = [jsonDict objectForKey:@"ImageName"];
cell.textLabel.textAlignment=NSTextAlignmentRight;

NSData *imgData = [NSData dataWithBase64EncodedString:[jsonDict objectForKey:@"ImageData"]];
cell.imageView.image = [UIImage imageWithData:imgData];

提前致谢。

最后我达到了目标，在单个UITableViewCell中显示两个已解析的图像我使用的代码是

UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:@"MyCell"];
if (cell==nil)
{
     cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"CellIdentifier"];

    UIImageView *imageView1=[[UIImageView alloc]init];
    imageView1.frame=CGRectMake(0, 0,50,cell.frame.size.height);
    imageView1.tag=1000;
    [cell.contentView addSubview:imageView1];

    UIImageView *imageView2=[[UIImageView alloc]init];
    imageView2.frame=CGRectMake(cell.frame.size.width-50, 0, 50,cell.frame.size.height);
    imageView2.tag=2000;
    [cell.contentView addSubview:imageView2];

}


jsonDict = [jsonArr objectAtIndex:indexPath.row];
NSLog(@"imagess%@",jsonDict);
cell.textLabel.text = [jsonDict objectForKey:@"ImageName"];
cell.textLabel.textAlignment=NSTextAlignmentCenter;



if ([jsonDict objectForKey:@"RefImageData"] == [NSNull null]) {
    // photo is null
    NSData *imgData = [NSData dataWithBase64EncodedString:[jsonDict objectForKey:@"ImageData"]];


    UIImageView *imageView=(UIImageView *)[cell.contentView viewWithTag:1000];
    imageView.image=[UIImage imageWithData:imgData];
}
else {
    // photo isn't null
    NSData *imgData = [NSData dataWithBase64EncodedString:[jsonDict objectForKey:@"ImageData"]];

    NSData *refimage=[NSData dataWithBase64EncodedString:[jsonDict objectForKey:@"RefImageData"]];


    UIImageView *imageView=(UIImageView *)[cell.contentView viewWithTag:1000];
    imageView.image=[UIImage imageWithData:imgData];

    UIImageView *imageView2=(UIImageView *)[cell.contentView viewWithTag:2000];
    imageView2.image=[UIImage imageWithData:refimage];


}
return cell;

您需要创建一个自定义UITableViewCell子类，其中包含两个图像视图。然后你可以像在这里一样从你的json中分配两个图像。

Apple provides an example how you can do that，还有很多教程，只搜索“自定义uitableviewcell子类教程”。
