查了好久，今天才在官网论坛找到了方法，因为好像3.3之后就不是导一个现有项的那种方法了。闲话不多说，创建方法只需要两步

1. #include “ui\UIScale9Sprite.h”
2. 使用的时候这样写才能不出错
   auto nineGirl = ui::Scale9Sprite::create(“button.png”);

贴一个自己的非常简单的代码

#include "HelloWorldScene.h"
#include "ui\UIScale9Sprite.h"
using namespace cocos2d;

Scene* HelloWorld::createScene()
{
    // 'scene' is an autorelease object
    auto scene = Scene::create();

    // 'layer' is an autorelease object
    auto layer = HelloWorld::create();

    // add layer as a child to scene
    scene->addChild(layer);

    // return the scene
    return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }

    Size visibleSize = Director::getInstance()->getVisibleSize();
    Vec2 origin = Director::getInstance()->getVisibleOrigin();

    auto nineGirl = ui::Scale9Sprite::create("button.png");
    nineGirl->setContentSize(Size(200,200));
    nineGirl->setPosition(Vec2(200,200));
    this->addChild(nineGirl);
    return true;
}


void HelloWorld::menuCloseCallback(Ref* pSender)
{
    Director::getInstance()->end();

#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
    exit(0);
#endif
}
