下面是Cocos2d-x在运行时候修改分辨率：

cocos2d::CCEGLView* eglView = cocos2d::CCEGLView::sharedOpenGLView();
cocos2d::CCDirector* pDirector = cocos2d::CCDirector::sharedDirector();

if ( eglView == NULL || pDirector == NULL )
{
return false;
}

eglView->setFrameSize(width, height);

eglView->setDesignResolutionSize(width, height, kResolutionNoBorder);

cocos2d::CCScene *pScene = HelloWorld::scene();
pDirector->replaceScene(pScene);
