Question

我已经设法让我的游戏在发布时将玩家签入游戏中心但是当达到高分时它只是将其保存在游戏中而不是将其发送到游戏中心。无论我把

放在哪里

[self reportScore];

它似乎使模拟器崩溃，我已经附加了我的视图controller.m文件，如果你可以帮我一个方法让我的游戏发送高分给游戏中心所以我可以继续发布排行榜到显示应用程序中的排行榜。我按照http://www.appcoda.com/ios-game-kit-framework/

的方式学习本教程

                 _gameCenterEnabled = YES;

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

您可以尝试这个简单的代码段是否适合您？ _localPlayer是指使用身份验证处理程序设置的实例变量。

- (IBAction)doAddAScore:(id)sender {
    GKLocalPlayer *lp = [GKLocalPlayer localPlayer];
    NSInteger score = 100;
    if (lp && lp.isAuthenticated) {
        NSString *lbid = @"your.leaderboard.id";
        GKScore *gkScore = [[GKScore alloc] initWithLeaderboardIdentifier:lbid player:lp];
        gkScore.value = score;
        [GKScore reportScores:@[gkScore] withCompletionHandler:^(NSError * _Nullable error) {
            NSLog(@"GKScore::reportScores completed - error : %@", error);
        }];
    } else {
        NSLog(@"reporting score: localPlayer nil or not authenticated");
    }
}

此代码来自我的测试原型，我用它来解析游戏邀请并且分数提交刚刚起作用。代码中没有其他部分可以处理分数提交。

游戏不会向游戏中心发送高分
