Ribbit iOS - FriendsViewController does NOT sync with back-end after First Open

After tapping on Edit and removing or adding friends, I tap on back button and the FriendViewController does NOT sync with the back-end. Actually I can tap even on Inbox and tap again on Friends, it does not sync with the back-end anyway.

this is my viewDidLoad Method:

- (void)viewDidLoad
    [super viewDidLoad];

    self.friendsRelation = [[PFUser currentUser] objectForKey:@"friendsRelation"];
    PFQuery *query = [self.friendsRelation query];
    [query orderByAscending:@"username"];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if (error) {
            NSLog(@"Error: %@", [error userInfo]);
        } else {
            self.friends = objects;
            [self.tableView reloadData];


Is there something that I could do ? Why it is not showed on the video ?

Try moving it to viewWillAppear

That will load the list every time the view is shown. ViewDidLoad loads only when that view is hit the first time.

OK, sorry for this. I've just found the answer in the next video at Stage 4.

I posted it here because for me there is no sense in solving this in a stage called: "Capturing Photo and Video Using UIImagePickerController", naturally I assumed that the issue wasn't solved.
