关于iPhone：显示游戏中心GKMatchmakerViewController关闭其他视图

Displaying Game Center GKMatchmakerViewController dismisses other view

尝试在游戏视图上显示GKMatchmakerViewController时出现问题。

通常我会通过自动匹配2个对手来编程创建多人游戏，效果很好。

但是当我尝试显示标准的Game Center对接会视图时，它会关闭我的游戏视图，并将我推回菜单。

菜单视图->游戏视图。

我认为问题可能是我的菜单视图充当了我的主视图，并且在显示"游戏中心"视图时删除了所有其他视图(因为此时只能显示一个视图控制器)。

我设置视图层次结构错误吗？在显示"游戏中心"视图时，应该如何做才能使我的"游戏视图"不被关闭？

编辑-使用调用GKMatchMakerViewController的代码进行更新

GameviewController，当我想显示Game Center匹配控制器时调用的方法

- (void)presentCustomVSBattle {

ourRandom = arc4random();
[self setGameState:kGameStateWaitingForMatch];

AppDelegate * delegate = (AppDelegate *) [UIApplication sharedApplication].delegate;

[[GCHelper sharedInstance] findCustomMatchWithMinPlayers:2 maxPlayers:2 viewController:delegate.viewController delegate:self];
}

//在GCHelper.m

中调用此方法
