Adding a pointer field to a subclass of PFUser

Question

I'd like to add a pointer field to my PFUser subclass, managed by the PFUser subclass. Ideally, the pointer object would be available automatically on the PFUser subclass - saved and fetched when the user is saved and fetched.

With any other PFObject subclass, I would simply add a Dynamic property and be sure to use includeKey when querying.

However, for a PFUser subclass, I'm never actually querying. How can I force the pointer object to fetch?

It's an easy, two-step process in objective-c, even with a subclassed :

1. Create a local object that represents the pointer, even though you don't have the data yet

2. Use fetchIfNeededInBackground to populate the pointer object locally

   PFObject *yourPointerObject = [[PFUser currentUser] objectForKey"pointerKey"];
   [yourPointerObject fetchIfNeededInBackground];
