iphone - 从 webview 返回后自动旋转屏幕错误

Question

我使用cocos结合admob，正常情况下我的应用程序运行良好，但是在点击广告并返回游戏后，它的布局错误

这是我的轮换代码

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

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGRect rect;

    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];
    EAGLView *glView = [director openGLView];
    float contentScaleFactor = [director contentScaleFactor];

    if (contentScaleFactor != 1) {
        rect.size.width *= contentScaleFactor;
        rect.size.height *= contentScaleFactor;
    }
    glView.frame = rect;
}

感谢您的帮助!

我之前也遇到过类似的问题，我的错误做法是创建了一个新的 UIViewController 并将其设置为 AdMob View 的 rootViewController。我现在在我的应用程序中所做的事情如下:

adMobView.rootViewController = [RootViewController sharedInstance];
[[[CCDirector sharedDirector] openGLView] addSubview:adMobView];

其中[RootViewController共享实例]是一个类方法，它返回应用程序中RootViewController的唯一实例。引用https://stackoverflow.com/a/10222956/1241690 .

(对于cocos2d 2.x，第二行应该是:

[[[CCDirector sharedDirector] view] addSubview:adMobView];
