我有一个表格视图，列出了我拥有的游戏地图。当我单击一个时，会加载另一个包含 cocos2d 场景的故事板。
我第一次加载场景时，一切都完美加载。但是，我第二次尝试加载场景（从导航控制器返回并单击同一张地图或另一张地图）时，我得到一个显示 fps 的空白屏幕，但没有其他内容。
这是我在 mapViewController 中的代码（包含 cocos2d）
- (void)setupCocos3D { //called from viewDidLoad
[[CCDirector sharedDirector] setOpenGLView:openGLView];
((ViewInterface*)[ViewInterface sharedViewInterface]).currentScene = [testScene scene];
// Create the customized CC3Layer that supports 3D rendering.
CC3Layer* cc3Layer = [HelloWorldLayer node];
// Create the customized 3D scene and attach it to the layer.
// Could also just create this inside the customer layer.
cc3Layer.cc3Scene = ((ViewInterface*)[ViewInterface sharedViewInterface]).currentScene;
// Assign to a generic variable so we can uncomment options below to play with the capabilities
CC3ControllableLayer* mainLayer = cc3Layer;
mainLayer.contentSize = CGSizeMake(2048, 1320);
[CCDirector sharedDirector].animationInterval = (1.0f / kAnimationFrameRate);
[CCDirector sharedDirector].displayStats = YES;
[[CCDirector sharedDirector] enableRetinaDisplay: YES];
((ViewInterface*)[ViewInterface sharedViewInterface]).mainLayer = mainLayer;
[[CCDirector sharedDirector] runWithScene:((ViewInterface*)[ViewInterface sharedViewInterface]).mainLayer];
}
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[[CCDirector sharedDirector] end];
}
我能看到 fps 真的很奇怪，因此似乎唯一的问题是场景或图层。
