游戏中心：匹配

Question

在我的纸牌游戏游戏中，我尝试创建一个匹配项，对于某个部分来说，它可以工作;匹配成功创建

- (void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match { 

self.match = match; 
match.delegate = self; 
if (!_matchStarted && match.expectedPlayerCount == 0) { 
    NSLog(@"Ready to start match!"); 
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; 
    UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"GameVC"]; 
    vc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
    [viewController presentViewController:vc animated:YES completion:nil]; 
    //[viewController dismissViewControllerAnimated:YES completion:nil]; 
} 
} 

后，我想GKMatchmakerViewController被解雇，我想显示的“VC” UIViewController。在上面的例子中，这是完成的，但GKMatchmakerViewController不会被解雇。

如果我删除了评论引号，它会在它以某种方式被解散后加载，如果我将该行放在presentViewController行之上，则会出现一个错误消息，指出我试图在视图控制器上呈现视图控制器在视图层次结构中。

如何解除GKMVC并在“相同”时间显示“vc”？

谢谢！

您需要关闭该GKMatchMakerViewController，然后用你的当前视图控制器来呈现新的模式：

if (!_matchStarted && match.expectedPlayerCount == 0) { 
    NSLog(@"Ready to start match!"); 
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; 
    UIViewController *vc = [sb instantiateViewControllerWithIdentifier:@"GameVC"]; 
    vc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
    [viewController dismissViewControllerAnimated:YES completion:nil]; 
    [self presentViewController:vc animated:YES completion:nil]; 
} 

编辑：一招让当前根视图控制器为[[UIApplication sharedApplication] delegate].window.rootViewController。所以你应该能够用这个来展示你的模态：

[[[UIApplication sharedApplication] delegate].window.rootViewController presentViewController:vc animated:YES completion:nil];
