Error on Challenge task 2 of 3

HI All,

Having a bit of an issue with this challenge.

It is asking for the following:

Now send the 'findObjectsInBackgroundWithBlock' message to the 'query' variable. Use the code that is commented out as the basics for the block you pass in.

I get the following error:

Bummer! Compilation Error! Make sure you have the correct syntax and are calling the method and passing the block like in the video.

This is the code that I use:

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

@implementation AppsViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    PFQuery *query = [PFQuery queryWithClassName:@"Apps"];     
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (error) {
        NSLog(@"Error: %@ %@", error, [error userInfo]);
    }
    else {
    }
}];
@end

you closed your method call to findObjectsInBacgroundWithBlock after the wrong curly brace. you have

- (void)viewDidLoad {
    [super viewDidLoad];
    PFQuery *query = [PFQuery queryWithClassName:@"Apps"];     
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
    if (error) {
        NSLog(@"Error: %@ %@", error, [error userInfo]);
    }
    else {
    }
}];

see how you closed it after the curly brace that ends the viewDidLoadImplentation? You should have

- (void)viewDidLoad {
    [super viewDidLoad];

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


    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (error) {
            NSLog(@"Error: %@ %@", error, [error userInfo]);
        }
        else {

        }
    //this is where you need to close it
    }];

//this is where you closed it before    
}
