编写多个排行榜

Question

我正在做一个游戏，在这个游戏中，玩家可以根据他们所做的选择获得一个积极的高分或一个负的低分。高分一直工作得很好，但我对低分有些困难。

-(void)authenticateLocalPlayer{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];

localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error){
    if (viewController != nil) {
        [self presentViewController:viewController animated:YES completion:nil];
    }
    else{
        if ([GKLocalPlayer localPlayer].authenticated) {
            _gameCenterEnabled = YES;

            // Get the default leaderboard identifier.
            [[GKLocalPlayer localPlayer] loadDefaultLeaderboardIdentifierWithCompletionHandler:^(NSString *leaderboardIdentifier, NSError *error) {

                if (error != nil) {
                    NSLog(@"%@", [error localizedDescription]);
                }
                else{
                    _leaderboardIdentifier = leaderboardIdentifier;
                }
            }];
        }

        else{
            _gameCenterEnabled = NO;
        }
    }
};
}


-(void)reportScore{

GKScore *highscore = [[GKScore alloc] initWithLeaderboardIdentifier:_leaderboardIdentifier];
highscore.value = HighScoreNumber;

[GKScore reportScores:@[highscore] withCompletionHandler:^(NSError *error) {
    if (error != nil) {
        NSLog(@"%@", [error localizedDescription]);
    }
}];


-(void)showLeaderboardAndAchievements:(BOOL)shouldShowLeaderboard{
GKGameCenterViewController *gcViewController = [[GKGameCenterViewController alloc] init];

gcViewController.gameCenterDelegate = self;

if (shouldShowLeaderboard) {
    gcViewController.viewState = GKGameCenterViewControllerStateLeaderboards;
    gcViewController.leaderboardIdentifier = _leaderboardIdentifier;
}
else{
    gcViewController.viewState = GKGameCenterViewControllerStateAchievements;
}

[self presentViewController:gcViewController animated:YES completion:nil];

}

你会注意到排行榜鉴别器，它对于向默认排行榜报告分数很有用，但是当我试图让它对两个不同的排行榜工作时，代码关闭了。

我试着将这个添加到“报告分数”中：

GKScore *lowscore = [[GKScore alloc] initWithLeaderboardIdentifier:_leaderboardIdentifier];
lowscore.value = LowScoreNumber;

[GKScore reportScores:@[lowscore] withCompletionHandler:^(NSError *error) {
    if (error != nil) {
        NSLog(@"%@", [error localizedDescription]);
    }
}];

}

然后，我更改了排行榜标识符以匹配它的shouldShowLeaderboardandAchievements，但是我不确定我需要如何更改authenticateLocalPlayer和itunesconnect。

我有一些使用游戏中心的经验。我在App Store上有两个游戏，它们有多个排行榜(Squared!！和素数！)。

我没有让每个排行榜都有一个方法，而是创建了一个提交分数的方法。以下是该方法：

-(void) submitScore:(int64_t)score Leaderboard: (NSString*)leaderboard
{

    //1: Check if Game Center
    //   features are enabled
    if (!_gameCenterFeaturesEnabled) {
        return;
    }

    //2: Create a GKScore object
    GKScore* gkScore =
    [[GKScore alloc]
     initWithLeaderboardIdentifier:leaderboard];

    //3: Set the score value
    gkScore.value = score;

    //4: Send the score to Game Center
    [gkScore reportScoreWithCompletionHandler:
     ^(NSError* error) {

         [self setLastError:error];

         BOOL success = (error == nil);

         if ([_delegate
              respondsToSelector:
              @selector(onScoresSubmitted:)]) {

             [_delegate onScoresSubmitted:success];
         }
     }];


}

当你想提交你的高分时，你所要做的就是添加如下内容：

[[GCHelper sharedGameKitHelper] submitScore:myLowScore Leaderboard:TELS];
[[GCHelper sharedGameKitHelper] submitScore:myHighScore Leaderboard:TEHS];

GCHelper是包含我的submitScore:Leaderboard: method的类。

要在你的应用程序中查看排行榜或成就，请尝试以下命令：

- (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];
}

- (void) presentAchievements {
    GKGameCenterViewController* gameCenterController = [[GKGameCenterViewController alloc] init];
    gameCenterController.viewState = GKGameCenterViewControllerStateAchievements;
    gameCenterController.gameCenterDelegate = self;

我希望这能回答你的问题！
