我得到了 facebook sdk op 并运行。我尝试获取相册的所有照片。目前我正在使用这个：

NSString *S = [[NSString alloc] initWithFormat:@"%s%@%s","https://graph.facebook.com/",albumID, "/photos"];
[facebook requestWithGraphPath:S andDelegate:self];

我也得到了一个结果，我尝试将其解析为一组照片或照片 ID。但是我尝试了几个小时并在每个地方搜索网络，但我找不到解决方案。我究竟做错了什么？

- (void)request:(FBRequest *)request didLoad:(id)result


        for (NSDictionary *anAlbum in [result objectForKey:@"data"]) {
            [arrayAllPhotos addObject:[anAlbum objectForKey:@"id"]];

            NSString *url = [[NSString alloc] initWithFormat:@"https://graph.facebook.com/%@/picture",[arrayAllPhotos objectAtIndex:counter]];

            UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url]]];
        }
}

这是我从 Facebook 得到的 JSON。提前致谢！

when you add objects to your arrayAllPhotos use source instead of id:

[arrayAllPhotos addObject:[NSUrl urlWithString:[anAlbum objectForKey:@"source"]]];

oh and then when you want to use these images do this:

UIImage *image = [[UIImage imageWithData:[NSData dataWithContentsOfUrl:[arrayAllPhotos objectAtIndex:indexOfObjectYouWant]]]];

hope it helps
