我已经设法让我的游戏在发布时让玩家登录游戏中心，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

[self reportScore];

它似乎使模拟器崩溃，我已经附上了我的 view controller.m 文件，如果你能帮助我让我的游戏将高分发送到 Game Center，这样我就可以继续发布排行榜以显示排行榜应用程序。我正在关注本教程http://www.appcoda.com/ios-game-kit-framework/

 #import "ViewController.h"

 @interface ViewController ()

 @property (nonatomic, strong) NSString *leaderboardIdentifier;
 @property (nonatomic,assign) BOOL gameCenterEnabled;

 @implementation ViewController

-(void)reportScore{
     GKScore *score = [[GKScore alloc]   initWithLeaderboardIdentifier:_leaderboardIdentifier];
     score.value = HighScoreNumber;

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

-(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) {

                    }

你能试试这个简单的片段是否适合你吗？_localPlayer指的是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");
    }
}

这段代码来自我的一个测试原型，我用它来解决游戏邀请和分数提交。代码中没有其他部分处理分数提交。
