iOS Build a Self-Destructing Message iPhone App Retrieving and Viewing Data from Parse.com Retrieving Data from Parse.com

warning 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.

I 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]); }

}]; }
