Iphone Cocos3D-hello world场景在集成到uikit中时不显示
我想在我的一个视图中集成cocos3d。因此，我有一个普通的视图控制器（Iphone Cocos3D-hello world场景在集成到uikit中时不显示,iphone,objective-c,ipad,cocos2d-iphone,cocos3d,Iphone,Objective C,Ipad,Cocos2d Iphone,Cocos3d,我想在我的一个视图中集成cocos3d。因此，我有一个普通的视图控制器（MapEditorViewController）和一个视图，在我的视图控制器中，（我创建了一个IBOutlet CCGLView*openGLView），我希望cocos3d在其中。在我的视图控制器中，我有一个方法setupCocos3D： MapEditorViewController - (void)setupCocos3D { [[CCDirector sharedDirector] setOpenGLVie
