我遇到了这里描述的问题： https ://devforums.apple.com/thread/165384?tstart= 0 我的应用程序在尝试加载 GameCenter 登录屏幕时崩溃，因为屏幕是纵向的，而我的应用程序只支持横向。我已经尝试了上述线程中描述的所有解决方案，以及以下线程中的所有解决方案： Crash on presenting UIImagePickerController under iOS 6.0 And here: http://www.cocos2d-iphone.org/forum/topic/36639

任何解决方案都不起作用。要么崩溃仍然发生，要么登录工作正常，然后我的应用程序在横向和纵向之间自由旋转，或者它将自己锁定为纵向并搞砸了整个 UI。

我想要的是让 GameCenter 登录以纵向工作，然后让应用程序中的其他所有内容以横向工作。

这是我的应用程序中包含的所有旋转方法。这些来自 appdelegate.m 中的 myNavigationController 实现：

    -(NSUInteger)supportedInterfaceOrientations {

    // iPhone only
    if( [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone )
        return UIInterfaceOrientationMaskLandscape;

    // iPad only
    return UIInterfaceOrientationMaskLandscape;
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // iPhone only
    if( [[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone )
        return UIInterfaceOrientationIsLandscape(interfaceOrientation);

    // iPad only
    // iPhone only
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}


-(BOOL)shouldAutorotate{

    return NO;
 }

从 appDelegate.m 中的 AppController 实现：

    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

包含在 RootViewController.m 中：

    -(BOOL)shouldAutorotate{
        return NO;
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight|UIInterfaceOrientationMaskLandscapeLeft;
}


- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
        return NO;
    }


#if GAME_AUTOROTATION==kGameAutorotationNone
    return ( interfaceOrientation == UIInterfaceOrientationPortrait );

#elif GAME_AUTOROTATION==kGameAutorotationCCDirector
    if( interfaceOrientation == UIInterfaceOrientationLandscapeLeft ) {
        [[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeRight];
    } else if( interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        [[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeLeft];
    }


#elif GAME_AUTOROTATION == kGameAutorotationUIViewController
#else
#error Unknown value in GAME_AUTOROTATION

#endif // GAME_AUTOROTATION
    // Shold not happen
    return NO;
}

kGameAutorotationUIViewController

#if GAME_AUTOROTATION == kGameAutorotationUIViewController
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{

    CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGRect rect = CGRectZero;

    if(toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
        rect = screenRect;

    else if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight){
        rect.size = CGSizeMake( screenRect.size.height, screenRect.size.width );
    }


    CCDirector *director = [CCDirector sharedDirector];
    UIView *glView = [[CCDirector sharedDirector] view];;
    float contentScaleFactor = [director contentScaleFactor];

    if( contentScaleFactor != 1 ) {
        rect.size.width *= contentScaleFactor;
        rect.size.height *= contentScaleFactor;
    }
    glView.frame = rect;
}
#endif // GAME_AUTOROTATION == kGameAutorotationUIViewController

几天前刚刚在这里回答了这个问题： Cocos 2d 2.0 shouldAutorotate not working？

有关于您需要做什么才能使其在该答案中起作用的说明。希望这可以帮助！
