Question

尝试实现多人游戏。使用Game Center - Sending and receiving data中的示例。

一切似乎都没问题，但在apple documentation中也有关于邀请处理程序的说法。

[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
   // Insert application-specific code here to clean up any games in progress.
   if (acceptedInvite) {
        GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
        mmvc.matchmakerDelegate = self;
        [self presentModalViewController:mmvc animated:YES];
    } else if (playersToInvite) {
        GKMatchRequest *request = [[[GKMatchRequest alloc] init] autorelease];
        request.minPlayers = 2;
        request.maxPlayers = 4;
        request.playersToInvite = playersToInvite;

        GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithMatchRequest:request] autorelease];
        mmvc.matchmakerDelegate = self;
        [self presentModalViewController:mmvc animated:YES];
    }
};

问题很简单：我不知道在哪里添加此代码。

Answer 1

如文档中所述

您的申请应该设置邀请处理程序早在申请后可能启动;一个合适的地方处理程序在完成块中你提供了在执行后执行本地玩家已通过身份验证。

在代码的某处，你应该用这样的东西验证本地播放器

[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
    if (error == nil) {
        // Insert your piece of code here
    } else {
        // Handle the error
    }
}];

希望有所帮助

我的代码如下，并且效果很好。在authenticateLocalUser中，添加以下代码：

[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
    [GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {  // Add for invite handler
        // Insert application-specific code here to clean up any games in progress.
        if (acceptedInvite) {
            GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] ;
            mmvc.matchmakerDelegate = self;
            // [self presentModalViewController:mmvc animated:YES];
            [_delegate matchStart];
        } else if (playersToInvite) {
            GKMatchRequest *request = [[GKMatchRequest alloc] init] ;
            request.minPlayers = 2;
            request.maxPlayers = 2;
            request.playersToInvite = playersToInvite;

            GKMatchmakerViewController *mmvc = [[GKMatchmakerViewController alloc] initWithMatchRequest:request] ;
            mmvc.matchmakerDelegate = self;
            // [self presentModalViewController:mmvc animated:YES];
            [_delegate matchStart];
        }
    };

    [self callDelegateOnMainThread:@selector(processGameCenterAuth:) withArg:NULL error:error];
}];
