我目前正在开发Game Center Multiplayer，并遇到了几个障碍。目前我的代码将通过验证用户显示匹配器视图并开始匹配就好了。然而，当我尝试邀请一位朋友参加比赛时，要求播放比赛的警报视图显示当我接受它时会将我带到配对视图控制器并说它正在等待我的其他设备上的其他玩家它也说它正在等待让其他玩家回应。最终在一段时间后，它说邀请被取消了。我没有使用模拟器我有2个设备都有单独的游戏中心配置文件。一个是IOS 4.2，另一个是IOS 4.3。我不知道会出现什么问题。我的所有多人游戏代码都在下面。此外，为了向任一设备发送数据，我很想知道一个好网站，以了解更多相关信息。我很高兴看到你们都能想到的。 感谢

当您接受邀请时，NSLog：邀请收到的内容是否会在控制台中打印？
[delegate inviteAccepted]方法应该处理当玩家接受邀请时会发生什么。由于您不知道当前正在显示什么视图，因此这会变得相当繁琐。你应该以某种方式找到它，推动视图。然后从该视图中，应用程序应呈现matchMaker viewController。我的邀请块看起来像这样：
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite){
NSLog(@"Invite");
if([AppDelegate mainMenuController].presentedViewController!=nil) {
[[AppDelegate mainMenuController] dismissViewControllerAnimated:NO completion:^{
}];
}
self.pendingInvite = acceptedInvite;
self.pendingPlayersToInvite = playersToInvite;
[[AppDelegate mainMenuController] presentViewController:[AppDelegate mainMenuController].multiGameMenu animated:NO completion:^{
[[AppDelegate mainMenuController].multiGameMenu duel:nil];
}];
};
其中multiGameMenu只是一个菜单，决斗方法只是创建一个游戏实例并调用findMatchWithMaxPlayers：int MinPlayers：int方法。让我知道它是怎么回事!!

尝试使用：
- (void)matchmakerViewController:(GKMatchmakerViewController *) viewController
didReceiveAcceptFromHostedPlayer:(NSString *)playerID
{
[viewController setHostedPlayer:playerID connected:YES];
}
我希望它有所帮助！
