Extra Credit ProfileViewController

Hi guys , I'm struggling with the query of this extra credit. Any suggestions 

PFQuery *query = [PFUser query];

[query whereKey:@"username" equalTo:self.userId];

[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (error) {


        NSLog(@"Error: %@ %@", error, [error userInfo]);

    } else {
           self.users = objects;
        PFUser *foundUser = [self.users objectAtIndex:0];//I'm pretty sure this isn't how I should do it, I set PFUser to the query but it gives //me an error . 
        self.userNameLabel.text = foundUser.username;
        NSLog(@"Works");
    }
}];

I'm trying to pull my data from parse. And then display the data into my text labels.

I'm trying to pull data from the selected user(from my table) via query and then set the data equal to my labels. But I'm struggling and I don't know how.

All of it is declared under my viewDidLoad on the ProfileViewController.m

  • (void)viewDidLoad { [super viewDidLoad];

    PFQuery *query = [PFUser query];

    [query whereKey:@"username" equalTo:self.userId];

    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) {

        NSLog(@"Error: %@ %@", error, [error userInfo]);

} else {

   self.users = objects;
    PFUser *foundUser = [self.users objectAtIndex:0];
    self.userNameLabel.text = foundUser.username;
    NSLog(@"Works");
}

    }];

}

Okay I fixed it a bit , but now my labels are returning null. This is all under viewDidLoad

PFUser *selectedUser = [PFQuery getUserObjectWithId:self.userId]; NSLog(@"username: %@" , selectedUser.username); self.userNameLabel.text = selectedUser.username; self.emailLabel.text = selectedUser.email;
