Question

我得到了facebook sdk op并且正在运行。我尝试获取专辑的所有照片。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。但我试了几个小时，每次都在网上搜索，但我找不到解决办法。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回来的JSON。提前谢谢！

Answer 1

当您向arrayAllPhotos使用source而不是id添加对象时：

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

哦，然后当你想使用这些图像时：

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