How do I get the Facebook user Id from the Facebook object in the iOS SDK?

Question

I see that the access token is available in the Facebook object, but I don't see a Facebook user Id.

I could make a graph request to "me" to get the Facebook Id, but I'd prefer not to make the extra api call.

There is an easy way to get this these days; assuming you already have a FBSession open, you could just do this:

[FBRequestConnection startForMeWithCompletionHandler:
  ^(FBRequestConnection *connection, id result, NSError *error)
  {
      NSLog(@"facebook result: %@", result);
  }];
