Full Stack JavaScript Techdegree Student 3,392 Pointswarning retrieving data: NSLog(@"Retrieved %d messages", [self.messages count]);
I get a warning: values of type 'NSUInteger' should not be used as format arguments;... I get this warning trying to add these lines:
NSLog(@"Retrieved %d messages", [self.messages count]);
When I downloaded the teachers exercise files, it gives me the same warning, even on his file.

Full Stack JavaScript Techdegree Student 3,392 PointsI got it figured out. This is my code and now it works:
(void)viewDidLoad { [super viewDidLoad];
PFUser *currentUser = [PFUser currentUser]; if ( currentUser) { NSLog(@"Current User: %@", currentUser.username);
} else { [self performSegueWithIdentifier:@"showLogin" sender:self]; }
}
(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated];
PFQuery *query = [PFQuery queryWithClassName:@"Messages"]; [query whereKey:@"recipientIds" equalTo:[[PFUser currentUser] objectId]]; [query orderByDescending:@"createdAt"]; [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) { NSLog(@"Error: %@ %@", error, [error userInfo]); } else { //We found messages self.messages = objects; [self.tableView reloadData]; NSLog(@"Retrieved %d messages", [self.messages count]); }
}]; }
