GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];

GKAchievementViewController *achievements = [[GKAchievementViewController
                                              alloc] init];
if (achievements != nil)
{
    achievements.achievementDelegate = self;
    [self presentViewController:achievements animated:YES completion:NULL];
}
{
    AudioServicesPlaySystemSound(SoundID);
}

- (void)achievementViewControllerDidFinish:(GKAchievementViewController
                                        *)viewController

}
}

我正在报告这样的分数

- (IBAction)ShareScore:(id)sender {
[self.gameCenterManager reportScore: counter forCategory: self.currentLeaderBoard];

GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if (leaderboardController != NULL)
{
    leaderboardController.category = self.currentLeaderBoard;
    leaderboardController.timeScope = GKLeaderboardTimeScopeToday;
    leaderboardController.leaderboardDelegate = self;
    [self presentViewController:leaderboardController animated:YES completion:NULL];
}
{
    AudioServicesPlaySystemSound(SoundID);
}
}

推荐答案

iOS 7将排行榜，成就等控制器组合到类。您可以使用参数，用于控制要显示的视图。

iOS 7 combines the leaderboards, achievements, etc. controllers together into the GKGameCenterViewController class. You use the viewState parameter to control which view you want displayed.

你想要做这样的事情提出/解除排行榜：

You'll want to do something like this to present/dismiss the leaderboards:

- (void) presentLeaderboards {
    GKGameCenterViewController* gameCenterController = [[GKGameCenterViewController alloc] init];
    gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
    gameCenterController.gameCenterDelegate = self;
    [self presentViewController:gameCenterController animated:YES completion:nil];
}

- (void) gameCenterViewControllerDidFinish:(GKGameCenterViewController*) gameCenterViewController {
    [self dismissViewControllerAnimated:YES completion:nil];
}

同样，为了展示成就，你可以这样做：

Similarly, for presenting achievements, you can do this:

- (void) presentAchievements {
    GKGameCenterViewController* gameCenterController = [[GKGameCenterViewController alloc] init];
    gameCenterController.viewState = GKGameCenterViewControllerStateAchievements;
    gameCenterController.gameCenterDelegate = self;
    [self presentViewController:gameCenterController animated:YES completion:nil];
}

报告得分如下所示：

- (void) reportHighScore:(NSInteger) highScore forLeaderboardId:(NSString*) leaderboardId {
    if ([GKLocalPlayer localPlayer].isAuthenticated) {
        GKScore* score = [[GKScore alloc] initWithLeaderboardIdentifier:leaderboardId];
        score.value = highScore;
        [GKScore reportScores:@[score] withCompletionHandler:^(NSError *error) {
            if (error) {
                NSLog(@"error: %@", error);
            }
        }];
    }
}
