ios - Facebook sdk io 从相册中获取照片

Question

我得到了 facebook sdk op 并正在运行。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 返回的 JSON。提前致谢!

Answer 1

当您将对象添加到您的 arrayAllPhotos 时，使用 source 而不是 id:

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

哦，然后当你想使用这些图像时，请执行以下操作:

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

希望对你有帮助
