无法接收游戏中心邀请-Java 学习之路

我正在尝试使用cocos2d为IOS开发实时多人游戏，使用http://www.raywenderlich.com/3325/how-to-make-a-simple-multiplayer-game-with-game-center-tutorial-part-22上的教程

一切正常，包括与随机播放器自动匹配，但邀请朋友不起作用，因为其他设备无法接收邀请 .

当我点击邀请朋友按钮然后通过使用标准游戏中心界面选择了一个朋友时，它表示等待（永远）并且没有任何反应 . 我的朋友无法收到游戏中心的邀请（没有通知） .

我可以通过使用附近的朋友功能邀请朋友（当在两个设备上启用此功能时），但是当附近的朋友被禁用时没有邀请通知 .

我花了几个小时在Google上搜索，发现了类似的情况，但没有解决方案 .

Some early feedback about possible answers:

我使用两个设备（一个iPhone和一个iPad），没有模拟器
iTunes连接上的所有设置都很好，包括多人游戏设置
我验证了两个设备都使用不同的测试帐户连接到沙箱
我已经在两台设备上检查了游戏中心的通知设置
我已经检查了所有代理/防火墙问题，并尝试了两种设备的WiFi和Cellular
为两个设备/帐户启用了游戏邀请
我已经检查过捆绑包ID，应用版本ID等...
两个设备都是IOS 6.x和App目标版本os IOS 5.0
我没有关于游戏中心的其他问题（排行榜，随机配对等...都很好）
我在Apple文档中提到的尽可能认证用户后立即调用了inviteHandler方法 .

Here is my Game center helper class Header file:

#import <Foundation/Foundation.h>
#import <GameKit/GameKit.h>
@protocol GCHelperDelegate
- (void)matchStarted;
- (void)matchEnded;
- (void)match:(GKMatch *)match didReceiveData:(NSData *)data
fromPlayer:(NSString *)playerID;
- (void)inviteReceived;
@end

@interface GCHelper : NSObject <GKMatchmakerViewControllerDelegate, GKMatchDelegate>{
BOOL gameCenterAvailable;
BOOL userAuthenticated;

UIViewController *presentingViewController;
GKMatch *match;
BOOL matchStarted;
id <GCHelperDelegate> delegate;

NSMutableDictionary *playersDict;

GKInvite *pendingInvite;
NSArray *pendingPlayersToInvite;
NSMutableArray *unsentScores;
}

@property (retain) GKInvite *pendingInvite;
@property (retain) NSArray *pendingPlayersToInvite;

@property (assign, readonly) BOOL gameCenterAvailable;

@property (retain) NSMutableDictionary *playersDict;

@property (retain) UIViewController *presentingViewController;
@property (retain) GKMatch *match;
@property (assign) id <GCHelperDelegate> delegate;

- (void)findMatchWithMinPlayers:(int)minPlayers maxPlayers:(int)maxPlayers
             viewController:(UIViewController *)viewController
                   delegate:(id<GCHelperDelegate>)theDelegate;

        return YES;
    }

    return NO;
}


@end

And Finally this is how I call the game center from my game layer (I tried two different options but none of them worked)

选项1

[[GCHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController: [[[UIApplication sharedApplication] keyWindow] rootViewController] delegate: self];

选项2

AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
        UINavigationController *viewController = [app navController];
        [[GCHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController:viewController delegate:self];

任何帮助将不胜感激 . 提前致谢...

我几个月来一直在处理多人游戏，邀请对我来说是一个真正的问题....和你一样，我用Ray的教程让我开始 . 我今天意识到Ray的代码中有一个错误，如果两个客户都有GKMatchmakerView，邀请将无效 . 当您第一次收到邀请时，您需要解雇它：

[gcdelegate.viewController  dismissViewControllerAnimated:YES
                                 completion:^{
                                     GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithInvite:pendingInvite];
                                     mmvc.matchmakerDelegate = self;
                                     [gcdelegate.viewController presentModalViewController:mmvc animated:YES];
                                     self.pendingInvite = nil;
                                     self.pendingPlayersToInvite = nil;
                                     boo_invite=true;
                                 }];

好吧，似乎它在我们的代码或网络设置没有任何变化的情况下再次起作用 . 我打开了Apple支持，错误记录等的门票......似乎其中一些工作......

现在我们知道这是Game Center沙箱中的一个错误 . 据我所知，游戏中心的sanbox版本并不稳定，Apple的人们对此服务的关注度不够 . 也无法检查互联网上的系统状态 .

我仍在继续与Apple支持人员讨论，以了解其原因，并在完成后分享所有对话 .

快乐的编码......
