14     Size visibleSize = Director::getInstance()->getVisibleSize();
15     Vec2 origin = Director::getInstance()->getVisibleOrigin();
16 
17     // 使用普通图片加载
18     Sprite *sprite = Sprite::create("button.png");
19     sprite->setPosition(Vec2(visibleSize.width / 2, visibleSize.height - 100));
20     this->addChild(sprite);
21 
22     // 使用 CCScale9Sprite 点9图
23     Scale9Sprite *scale9Sprite = Scale9Sprite::create("button.png");
24     scale9Sprite->setPosition(Vec2(visibleSize.width / 2, visibleSize.height * 0.3));
25     this->addChild(scale9Sprite);
26     // 使图片拉伸
27     scale9Sprite->setPreferredSize(Size(visibleSize.width * 0.8, visibleSize.height * 0.3));
28     scale9Sprite->setCapInsets(Rect(10, 10, 8, 8));
