Problems with Pointer<Class> in Parse.com - ios

Question

I've been using Parse.com for two months, but this is the first time I get a stupid error which I can't figure out.
I've been working in an app for iOS, but in the beginning I've been working with my own user. Now I registered other users and I want to fetch them from the server.
Well, I add one object in the table Changes, where I have a user property which is a Pointer<User> (it's not _User, but User, it's custom, just an object). Well, when I try to fetch all the rows I have, the one that I have with my user are ok:
so in my debug console is like :
but when I fetch other users:
my debug console is:
so there's not any variable!!!! :(
This is my code:
PFQuery *closestChanges = [PFQuery queryWithClassName:#"Changes"];
[closestChanges whereKey:#"coordinates" nearGeoPoint:geoPoint withinKilometers:0.5f];
[closestChanges findObjectsInBackgroundWithBlock:^(NSArray *changes, NSError *error) {
arrayChanges0 = [[NSMutableArray alloc] init];
arrayChanges1 = [[NSMutableArray alloc] init];
if (changes == nil && changes.count == 0) {
[_tableView reloadData];
return;
}
for (int i = 0; i < changes.count; i++) {
PFObject *currentChange = [changes objectAtIndex:i];
PFObject *user = [currentChange valueForKey:#"user"]; // here my user is null when it's other users.
PFObject *changeToStore = [PFObject objectWithClassName:#"Changes"];
[changeToStore setValue:currentChange[#"changetype"] forKey:#"type"];
[changeToStore setValue:currentChange[#"quantity"] forKey:#"quantity"];
[changeToStore setValue:currentChange[#"date"] forKey:#"enddata"];
[changeToStore setValue:user forKey:#"user"];
if ([currentChange[#"changetype"] intValue] == 0)
[arrayChanges0 addObject:changeToStore];
else
[arrayChanges1 addObject:changeToStore];
}
[_tableView reloadData];
}];
Is there anything wrong I'm doing by adding new users???
Thank you very much in advance.

When you fetch a pointer type from a table, you will only get back the metadata which is objectId. You need to call - (instancetype)includeKey:(NSString *)key in order to get all the data back from Changes table. If you query directly from User table, you will get all the data. But in this case, you User object is a subdocument from Changes objects.
Add this line before performing querying:
[closestChanges includeKey:#"user"]
