ios - Facebook 批量照片上传 iOS

Question

我在尝试让 Facebook iOS SDK 批量上传照片时遇到了一些问题。目前我可以一个一个上传，但如果可能的话我想批量处理请求。我读过这个post over and over连同 fb batch docs .这是我到目前为止所拥有的。

 Facebook *facebook = [(AppDelegate*)[[UIApplication sharedApplication] delegate] facebook]; 

        NSData *imageData = UIImagePNGRepresentation([imgs objectAtIndex:0]);
   NSString *jsonRequest1 = [NSString stringWithFormat:@"{ \"method\": \"POST\",    \"relative_url\": \"me/photos\", \"attached_files\": \"file1\" }"];
        NSString *jsonRequest2 = [NSString stringWithFormat:@"{ \"method\": \"POST\", \"relative_url\": \"me/photos\", \"attached_files\": \"file2\" }"];
        NSString *jsonRequestsArray = [NSString stringWithFormat:@"[ %@, %@ ]", jsonRequest1, jsonRequest2];


    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:jsonRequestsArray,@"batch",imageData,@"file1",imageData,@"file2" nil];

我正在将 imageData 映射到它正在寻找的键，但我每次都会收到此响应。

  {
        body = "{\"error\":{\"message\":\"File batch has not been attached\",\"type\":\"GraphBatchException\"}}";
        code = 400;
        headers =         (
                        {
                name = "WWW-Authenticate";
                value = "OAuth \"Facebook Platform\" \"invalid_request\" \"File batch has not been attached\"";
            },
                        {
                name = "HTTP/1.1";
                value = "400 Bad Request";
            },
                        {
                name = "Cache-Control";
                value = "no-store";
            },
                        {
                name = "Content-Type";
                value = "text/javascript; charset=UTF-8";
            }
        );
    },
        {
        body = "{\"error\":{\"message\":\"File file2 has not been attached\",\"type\":\"GraphBatchException\"}}";
        code = 400;
        headers =         (
                        {
                name = "WWW-Authenticate";
                value = "OAuth \"Facebook Platform\" \"invalid_request\" \"File file2 has not been attached\"";
            },
                        {
                name = "HTTP/1.1";
                value = "400 Bad Request";
            },
                        {
                name = "Cache-Control";
                value = "no-store";
            },
                        {
                name = "Content-Type";
                value = "text/javascript; charset=UTF-8";
            }
        );
    }
)

非常感谢任何帮助。

您是否尝试过使用适用于 iOS 6 的社交框架来分享照片？它允许您添加所有照片并共享它们。

- (IBAction)postToFacebook:(id)sender {
    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

        SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

        [controller setInitialText:@"First post from my iPhone app"];
        [controller addURL:[NSURL URLWithString:@"http://www.jinibot.com"]];
        [controller addImage:[UIImage imageNamed:@"socialsharing-facebook-image.jpg"]];

        //add as many images as you want
        [controller addImage:[UIImage imageNamed:@"socialsharing-facebook-image.jpg"]];
        [controller addImage:[UIImage imageNamed:@"socialsharing-facebook-image.jpg"]];
        [controller addImage:[UIImage imageNamed:@"socialsharing-facebook-image.jpg"]];

        [self presentViewController:controller animated:YES completion:Nil];
    }
}
