Hi, I tried to use cocos2d to load spine assets. Basically, I want to embed CCScene in top of UIView. I found this piece of code

- (void)setupCocos2D {
    CCGLView *glView = [CCGLView viewWithFrame:[[self view] frame]
                                   pixelFormat:kEAGLColorFormatRGB565   // kEAGLColorFormatRGBA8
                                   depthFormat:0                        // GL_DEPTH_COMPONENT16_OES
                        ];
    glView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    [self.view insertSubview:glView atIndex:0];
    

[[CCDirector sharedDirector] setView:glView];
CCScene *scene = [GoblinsExample scene];
[[CCDirector sharedDirector] runWithScene:scene];
}

After I run, I get this success log in XCode

This log exactly looks like the example project. It also showing CCDirectorDisplayLink layer in my view.

So my question is, did I miss something here? Any help would be appreciated. Thank you.
