Question

我使用下面的代码显示游戏中心，但如果我旋转iPhone没有任何事情发生，排行榜将会颠倒（不对方向做出回应）

代码

// Create leaderboard view w/ default Game Center style
        GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];

        // If view controller was successfully created...
        if (leaderboardController != nil)
        {
            // Leaderboard config
            leaderboardController.leaderboardDelegate = self;   // The leaderboard view controller will send messages to this object
            leaderboardController.category = category;  // Set category here
            leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;    // GKLeaderboardTimeScopeToday, GKLeaderboardTimeScopeWeek, GKLeaderboardTimeScopeAllTime

            // Create an additional UIViewController to attach the GKLeaderboardViewController to
            myViewController = [[UIViewController alloc] init];

            // Add the temporary UIViewController to the main OpenGL view
        //  [[[CCDirector sharedDirector] openGLView] addSubview:myViewController.view];
            [[[[CCDirector sharedDirector] openGLView] window] addSubview:myViewController.view];

            // Tell UIViewController to present the leaderboard
            [myViewController presentModalViewController:leaderboardController animated:YES];
            leaderboardController.view.transform = CGAffineTransformMakeRotation(CC_DEGREES_TO_RADIANS(90.0f));
            leaderboardController.view.bounds = CGRectMake(0, 0, 480, 320);
            leaderboardController.view.center = CGPointMake(160,240 );
        }

还有其他方法可以展示吗？任何帮助PLZ

谢谢

呵呵我发现可能是一个特定的解决方案，所以我用以下代码替换了if (leaderboardController != nil){...}。

代码：

if (leaderboardController != NULL) {
        leaderboardController.category = category; 

        leaderboardController.timeScope =GKLeaderboardTimeScopeAllTime;

        leaderboardController.leaderboardDelegate = self; 
        AppDelegate *delegate = [UIApplication sharedApplication].delegate; 

        [delegate.viewController presentModalViewController:leaderboardController animated:YES];
    }

还需要为viewController添加一个属性到AppDelegate.h首先添加一个属性声明，如下所示：

@property (nonatomic, assign) RootViewController *viewController;

然后切换到AppDelegate.m并合成变量，如下所示：

@synthesize viewController;

最后，由于此代码使用UIKit来显示视图控制器，因此最好将Cocos2D设置为使用UIViewController旋转。所以转到GameConfig.h，注释掉当前的#define GAME_AUTOROTATION kGameAutorotationNone，然后按如下所示进行设置：

#define GAME_AUTOROTATION kGameAutorotationUIViewController

你必须子类化你的两个视图控制器，父视图控制器和它提供的模态视图控制器（有人纠正我，如果我错了，但子控制器只处理轮换，如果他们的父也处理它们）并覆盖方法叫做：

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

对于两个方向（纵向和横向），您应该返回YES。默认情况下，iphone上的视图控制器仅为UIInterfaceOrientationPortrait返回YES，因此您必须自己处理旋转以进行横向渲染。

阅读此UIViewController Class Reference和此Technical Q&A QA1688: Why won't my UIViewController rotate with the device?。

如何让UIViewcontroller（游戏中心）响应方向（横向或纵向）？
