Ceator 动态设置纹理

var realUrl = cc.url.raw("resources/red.png");
this.gifts[this.index].getComponent(cc.Sprite).spriteFrame = new cc.SpriteFrame(realUrl);参考：https://blog.youkuaiyun.com/nynyvkhhiiii/article/details/78814165

creator2.0.10已经废弃上述方法

改为如下方式：

如：

cc.loader.loadRes('red', cc.SpriteFrame, (err, spriteFrame) =>{

this.gifts[this.index].getComponent(cc.Sprite).spriteFrame = spriteFrame;

});
