Photo upload with iOS-sdk gives (#324) Requires upload file , the file is there

Question

i tested it and read the Open-Graph API reference and i dont know what is wrong here i tested it in real device and in the simulator i try to upload photo with massage , this is as i read the best way to send from my game screen shot and status , mybe i wrong but this is what i found any i have this errors when i try to uload the photo :

this api method is used :

FBRequest *fbr = [FBRequest requestWithGraphPath:[NSString stringWithUTF8String:request->getGraphPath().c_str()]
                                          parameters:screw::ios::Helper::valueMap2nsDictionary(request->getParams())
                                          HTTPMethod:__getHTTPMethod(request->getMethod())];

The output log as i print it :

Why not use [FBRequest requestForUploadPhoto:(UIImage*)]? https://developers.facebook.com/docs/reference/ios/current/class/FBRequest/#requestForUploadPhoto :

That way you don't have to construct your own dictionary, and can just pass in a UIImage object.
