iOS Game Center Sandbox: Leaderboards show “No score”

So I am sending scores to the GC leaderboards, I receive no errors and the scores apprently send but I still see no scores listed in the leaderboards! The leaderboard itself is listed in Game Center there are just no scores.

According to a Google search and a question on here this could be resolved by attempting to log scores with more than one account. I have tried on three different accounts now both in Simulator (iOS5) and on my iPhone; none of them show any errors when submitting the scores.

  • The code that sends the score is here:

    - (void)reportScore:(NSString *)identifier score:(int)rawScore {
        GKScore *score = [[[GKScore alloc] initWithCategory:identifier] autorelease];
        score.value = rawScore;
        [scoresToReport addObject:score];
        [self save]; // Save here even though we save again in didEnterBackground, just in case of crash...
        if (!gameCenterAvailable || !userAuthenticated) return;
        [self sendScore:score];
    - (void)sendScore:(GKScore *)score {
        [score reportScoreWithCompletionHandler:^(NSError *error) {
            dispatch_async(dispatch_get_main_queue(), ^(void)
                               if (error == NULL) {
                                   NSLog(@"Successfully sent score!");
                                   [scoresToReport removeObject:score];                
                               } else {
                                   NSLog(@"Score failed to send... will try again later.  Reason: %@", error.localizedDescription);

    It suddenly started working (without any code change or even a recompile). I figure it takes a while for the leaderboards to actually appear, for me about 18 hours.

    Scores submitted within this time will still record, they just wont be visible instantly.

    I never got scores to add to the sandbox either, but here is the code I implemented, and it works fine with the version currently in the app store:

    GKScore * score = [[[GKScore alloc] initWithCategory:@"com.example.appname.scoreboardname"] autorelease];
    score.value = [[NSUserDefaults standardUserDefaults] integerForKey:@"NEWSCORE"];
    [score reportScoreWithCompletionHandler:^(NSError *error) {
        dispatch_async(dispatch_get_main_queue(), ^(void) {
            if (error == NULL) {
                NSLog(@"Score Sent");
            } else {
                NSLog(@"Score Failed");

    just make sure your GKScore.value is of type int64_t
