Parse.com - Getting pointer data contained in [PFUser currentUser]

Question

I am using the Parse.com iOS SDK, and I don't know what method I need to call to make sure that the PFUser currentUser contains the data for each pointer contained in it. It is probably very simple, but, as a beginner with this platform, I cannot find a solution.

Just to clarify, I am trying to get the username item in the following. It looks like it is always null, even though I am calling [[PFUser currentUser] fetchIfNeeded] before proceeding:

[[[PFUser currentUser] objectForKey:@"partner"] objectForKey:@"username"];

Thank you,

Andrea

You can do it in a single query by using includeKey:

PFQuery *query = [PFUser query];
[query includeKey:@"partner"];
[query includeKey:@"anotherPointerColumnName"];
[query getObjectInBackgroundWithId:[[PFUser currentUser] objectId]
                             block:^(PFObject *populatedUser, NSError *error) {
    PFObject *partner = populatedUser[@"partner"];
    PFObject *another = populatedUser[@"anotherPointerColumnName"];
}];

You can also use deeper levels, so if partner contained a pointer in it you needed called deeperPointerColumnName:

[query includeKey:@"partner.deeperPointerColumnName"];

Then in your completion block you can read it after you get the partner:

PFObject *partner = populatedUser[@"partner"];
PFObject *deeper = partner[@"deeperPointerColumnName"];

yes, includeKey: is the one, this make the query include child PFObjects that have a reference stored at the provided key

what if the it's not partner but partners (array of pointers)?

The other issue with this is, it does not persist in PFUser.currentUser().

Well, I found a workaround by myself. It looks like the solution is to call the fetch method on the pointer before proceeding:

[[[PFUser currentUser] objectForKey:@"partner"] fetch];

If there is a cleaner and swifter way of doing it (automatically for instance) I would really appreciate any advice.
