objective-c - 明确回答 playerToInvite 的用途

Question

Game Center 文档表明

playersToInvite parameter is non-nil when your application is launched directly from the Game Center application to host a match.

一些人问这究竟是如何工作的，即似乎没有办法从 Game Center 应用程序中选择 friend 并邀请他们从 Game Center 玩；仅当您在游戏中邀请时才有效。此文档是否已过时，或者是否有从 Game Center 开始特定游戏比赛的 secret 方法？我想测试我的 inviteHandler但我一直无法确定如何将此参数传递给应用程序。

[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite)
{
    // clean up games in progress here
    if (acceptedInvite)
    {
        NSLog(@"acceptedInvite %@", acceptedInvite);
        // The acceptedInvite parameter is non-nil when the application receives an 
        // invitation directly from another player.
        GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
        mmvc.matchmakerDelegate = self;
        [self disableHomeUI];
        [self presentModalViewController:mmvc animated:YES];
    }
    else if (playersToInvite)
    {
        NSLog(@"playersToInvite %@", playersToInvite);
        // playersToInvite parameter is non-nil when your application is launched 
        // directly from the Game Center application to host a match
        [self disableHomeUI];
        [self doPresentMatchMakerUIWithPlayersToInvite:playersToInvite];
    }
};

我认为这些文档并不能反射(reflect)当前的事态。据我所知，游戏中心应用程序目前甚至没有提供邀请 friend 玩的界面。

另外，检查开发者论坛(显然你有；))。来自库比蒂诺的人似乎认为这是不可能的。所以...
