Code Challenge: Retrieving and showing data from Parse.com- answer not working.

Code Challenge Task 2 of 2 I've tried this and it looks right. The block has a PFObject, and NSError and has NSLog in the block and it doesn't work? This is the question Now add a block parameter. It should have a PFObject as its first parameter and an NSError as its second parameter. Inside the block, use NSLog to log the message "Move retrieved!"

` #import "GameViewController.h"

import <Parse/Parse.h>

@implementation GameViewController

  • (void)viewDidLoad { [super viewDidLoad];

    PFQuery *query = [PFQuery queryWithClassName:@"Move"];

    [query getObjectInBackgroundWithId:@"1" block:^(PFObject *object, NSError *error) { NSLog(@"Move retrieved");

    } }];

@end

I just realized i had gotten the last two brackets mixed up, I had } }]; instead of }]; }

you have an extra curly brace at the end of your block and are also missing the ! on the end of your NSLog message

[query getObjectInBackgroundWithId:@"1" block:^(PFObject *object, NSError *error) { 
        NSLog(@"Move retrieved!");
    }];

not sure why it didnt work. I just passed jsut fine using it:

#import "GameViewController.h"
#import <Parse/Parse.h>

@implementation GameViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    PFQuery *query = [PFQuery queryWithClassName:@"Move"];

    // Insert code here!
    [query getObjectInBackgroundWithId:@"1" block:^(PFObject *object, NSError *error) { 
        NSLog(@"Move retrieved!");
    }];
}

@end
