        FIX_POS(ptNow.x, (VisibleRect::left().x+ballSize.width / 2.0), (VisibleRect::right().x - ballSize.width / 2.0f));
        FIX_POS(ptNow.y, (VisibleRect::bottom().y+ballSize.height / 2.0), (VisibleRect::top().y - ballSize.height / 2.0f));
        sprite->setPosition(ptNow);
    });
    
    _eventDispatcher->addEventListenerWithSceneGraphPriority(listener, sprite);
}

引用了 VisibleRect::bottom(), FIX_POS, VisibleRect::left(), TestCase::onEnter(), VisibleRect::right(), s_Ball , 以及 VisibleRect::top().
