我有一个带cocos场景的viewController，将其推入导航控制器中。在此视图控制器中，我具有以下方法:
-(void) viewDidLoad
{
[super viewDidLoad];
[_cc3FrameView addSubview: [self createGLView]];
CC3Backgrounder.sharedBackgrounder.shouldRunTasksOnRequestingThread = YES;
}
- (void) viewWillAppear:(BOOL)animated
{
if (!sceneInitialized) {
sceneInitialized = YES;
[CCDirector.sharedDirector runWithScene: [[self makePanoramaScene] asCCScene]];
} else {
[CCDirector.sharedDirector resume];
}
[CCDirector.sharedDirector startAnimation];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[[self runningPanoramaScene] sceneWillShow];
});
}
-(AxPanoramaScene *)runningPanoramaScene
{
CCScene *scene = [CCDirector.sharedDirector runningScene];
AxPanoramaLayer *panoramaLayer = [scene.children lastObject];
AxPanoramaScene *panoramaScene = (AxPanoramaScene *)panoramaLayer.cc3Scene;
return panoramaScene;
}
-(void)viewWillDisappear:(BOOL)animated
{
[CCDirector.sharedDirector pause];
}
当我按下该控制器时-一切正常，但是当我弹出该控制器并再次按下它时-我在日志中得到了亮粉红色屏幕并持续显示消息:

如何正确地将控制器与cocos场景一起推动几次？我将示例从cocos源代码更改为此代码。我在这里做错了什么？请注意-我的控制器不是
CCDirector-它仅包含一个带有Cocos场景的视图-实现类似于CC3DemoMultiScene。谢谢! 最佳答案
请记住CCDirector是UIViewController，但它也是一个单例，这给它带来了一些独特的细微差别。
例如，您似乎每次要替换控制器时都调用createGLView方法。如果遵循CC3DemoMultiScene设计，这将尝试在从CCGLView单例发布旧版本之前重新创建另一个CCDirector。
通常最好将您为其创建的CCDirector和CCGLView视为一个独立的可重用单元。弹出包含控制器时，将所有内容保持不变，并且每次都只需在视图层次结构中添加和删除CCGLView。
