Upload multiple photos on Facebook using Batch Request

Question

I had done following code with reference to following link to create batch request for uploading multiple photos in Facebook.

I had got some solution for uploading multiple photos on Facebook through this Facebook graph API.

CODE:

    NSString *jsonRequest1 = @"{ \"method\": \"POST\", \"relative_url\": \"me/photos\" , \"body\": \"Hello 1\", \"attached_files\": \"file1\" }";     NSString *jsonRequest2 = @"{ \"method\": \"POST\", \"relative_url\": \"me/photos\" , \"body\": \"Hello 2\", \"attached_files\": \"file2\" }";     NSString *jsonRequestsArray = [NSString stringWithFormat:@"[ %@, %@ ]", jsonRequest1, jsonRequest2];     NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:jsonRequestsArray,@"batch",nil];     [params setObject:UIImagePNGRepresentation(self.image1) forKey:@"file1"];     [params setObject:UIImagePNGRepresentation(self.image2) forKey:@"file2"];     [objFacebook requestWithGraphPath:@"me" andParams:params andHttpMethod:@"POST" andDelegate:self]; 

Now when I am running this code I got the following output.

Result Dictionary in - (void)request:(FBRequest *)request didLoad:(id)result

(         {         body = "{\"error\":0,\"error_description\":\"File file1 has not been attached\"}";         code = 400;         headers =         (                         {                 name = "HTTP/1.1";                 value = "400 Bad Request";             },                         {                 name = "Content-Type";                 value = "text/javascript; charset=UTF-8";             }         );     },         {         body = "{\"error\":0,\"error_description\":\"File file2 has not been attached\"}";         code = 400;         headers =         (                         {                 name = "HTTP/1.1";                 value = "400 Bad Request";             },                         {                 name = "Content-Type";                 value = "text/javascript; charset=UTF-8";             }         );     } ) 

I don't know how this files attached.. Can anyone help me to figure out this problem.

Is there any change in my code then please let me know.

Thanks in advance...

I recommend you use the new integrated Facebook API's in iOS 6 to do this instead of Facebook's API: https://developer.apple.com/videos/wwdc/2012/?id=306 there's a golden WWDC video for all social tasks. Plus using the new API's in iOS 6 is MUCH faster then using Facebooks.
