Code Challenge: Adding the Edit Friends Screen (2 of 3)

I have been struggling with this one for about a day now, and i simply can't figure it out.

The problem is as follows: "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."

This is what i have so far. The problem (i think) is in the else statement. I simply have no idea how to make this work. Please hint me in the right direction. Thanks.

    #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

Hi Jonas,

From the look of it you missed out the ':' after 'findObjectsInBackgroundWithBlock'.

So it should look like this - 

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

        }
    }];

I am so confused i tried it with - PFQuery *query = [PFQuery queryWIthClassName@"Apps"]; and this does not work in the code,

but this does work below [PFQuery queryWithClassName:@"Apps"] which is weird.

my code for the second part is below and doesn't work I need help please!

import "AppsViewController.h"

import <Parse/Parse.h>

@implementation AppsViewController

  • (void)viewDidLoad { [super viewDidLoad];

    [PFQuery queryWithClassName:@"Apps"];

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

    }

    }]; }
