【中文标题】Facebook sdk io 从相册中获取照片

【英文标题】：Facebook sdk io getting photo's from album

【发布时间】：2012-07-28 17:43:22

【问题描述】：

我得到了 facebook sdk op 并且正在运行。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 获得的 JSON。提前致谢！

【问题讨论】：

这是完美的。 NSString *graphPath = [[NSString alloc] initWithFormat:@"%@/photos",albumId]; Facebook *fb = //你的 facebookSDK; [fb requestWithGraphPath:graphPath andDelegate:self];

【参考方案1】：

当您向arrayAllPhotos 添加对象时，请使用source 而不是id：

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

哦，然后当您想使用这些图像时，请执行以下操作：

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

希望对你有帮助
