iOS FacebookSDK图像共享

Question

I am using the following code to upload an image from my iOS to Facebook.

NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
[params setObject:@"MY TEST MSG..." forKey:@"message"];
[params setObject:UIImagePNGRepresentation(self.editImageView.image) forKey:@"picture"];


[[FBSDKGraphRequest alloc] initWithGraphPath:@"me/photos" parameters:params HTTPMethod:@"POST"] startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
        if (!error) {
            NSLog(@"uploaded");
        } else {
            NSLog(@"Graph API Error: %@", [error description]);
        }
}];

My app got stuck for couple of minutes and show the error message. Can any one please help me?

NSMutableDictionary *variables = [NSMutableDictionary dictionaryWithCapacity:3];
UIImage *picture = FilterImage;
FbGraphFile *graph_file = [[FbGraphFile alloc] initWithImage:picture];
[variables setObject:graph_file forKey:@"file"];
[variables setObject:[NSString stringWithFormat:@"Hello testin"] forKey:@"message"];
[fbGraph doGraphPost:@"me/photos" withPostVars:variables];
NSLog(@"Now log into Facebook and look at your profile & photo albums...");
