Game Center leaderboard shows one result

Question

I've sent scores to the leaderboard with different test accounts but when I try to see the leaderboard I can only see the score from the account that I'm logged in. I used this code to send the scores :

    - (void)reportScore:(int64_t)score forLeaderboardID:(NSString*)identifier
{
    GKScore *scoreReporter = [[GKScore alloc] initWithLeaderboardIdentifier: @"GHS"];
    scoreReporter.value = score;
    scoreReporter.context = 0;

    [GKScore reportScores:@[scoreReporter] withCompletionHandler:^(NSError *error) {
        if (error == nil) {
            NSLog(@"Score reported successfully!");
        } else {
            NSLog(@"Unable to report score!");
        }
    }];
}

This is the code I'm using to show the leaderboard:

- (void)showLeaderboardOnViewController:(UIViewController*)viewController
{
    GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init];
    if (gameCenterController != nil) {
        gameCenterController.gameCenterDelegate = self;
        gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
        gameCenterController.leaderboardIdentifier = _leaderboardIdentifier;

        [viewController presentViewController: gameCenterController animated: YES completion:nil];
    }
}

Maybe it's because it is sandboxed and stuff? is this normal maybe? Thanks

Answer 1

I've had this issue before and after much searching it seems to be an error with sandbox accounts. I split my table into highest of all time, highest today and highest friend and in each case other higher scores from my other sandbox accounts were ignored. When I added another one of my accounts as a friend, they started sharing scores just fine.

I used code more or less identical to your own and submitted to the App Store where it was accepted, now it works fine with live accounts.
