在VC下编译可以出现效果，但是在IOS上毫无效果，发现网上也有人提出这个问题，先把方法记下来。

for iOS:

in AppController replace the gl-view creation with:

EAGLView *__glView = [EAGLView viewWithFrame: [window bounds] pixelFormat: kEAGLColorFormatRGBA8 depthFormat: GL_DEPTH24_STENCIL8_OES preserveBackbuffer: NO sharegroup: nil multiSampling: NO numberOfSamples: 0];

for Android:
in game activity:

public Cocos2dxGLSurfaceView onCreateView() { Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this); glSurfaceView.setEGLConfigChooser(5, 6, 5, 0, 16, 8); return glSurfaceView; }
