代码如下：
//精灵帧缓存读取plist
SpriteFrameCache *sfc = SpriteFrameCache::sharedSpriteFrameCache();
sfc->addSpriteFramesWithFile("protagonist_move/aaaa.plist");
//加载大图
auto sprites = SpriteBatchNode::create("protagonist_move/aaaa.png");
sprites->setPosition(Point::ZERO);
this->addChild(sprites, 1);
//从大图中截取小图创建精灵
auto s = Sprite::createWithSpriteFrameName("10020.png");
s->setPosition(Point(CCRANDOM_0_1() * 480, CCRANDOM_0_1() * 320));
this->addChild(s,3);
auto s1 = Sprite::createWithSpriteFrameName("10021.png");
s1->setPosition(Point(CCRANDOM_0_1() * 180, CCRANDOM_0_1() * 320));
this->addChild(s1,2);
运行后出现以下错误：
1>d:\cocos2d-x-3.17\tests\game2\classes\helloworldscene.cpp(125): warning C4996: ‘cocos2d::SpriteFrameCache::sharedSpriteFrameCache’: 被声明为已否决
1>d:\cocos2d-x-3.17\tests\game2\cocos2d\cocos\2d\ccspriteframecache.h(101): note: 参见“cocos2d::SpriteFrameCache::sharedSpriteFrameCache”的声明
如何修改？
