直接上代码，代码里的common.log请等同于cc.log
onLoad: function() {
let me = this;
cc.loader.loadRes("MjTile", function(err, prefab) {
if (err)
throw err;
me.MjTile = prefab;
//缓冲麻将子组件；
me.MjTilePool = new cc.NodePool();
let initCount = 5;
for (let i = 0; i < initCount; ++i) {
common.log(1);
me.MjTilePool.put(cc.instantiate(me.MjTile));
common.log(2);
}
});
},
我用模拟器运行出现的结果就是一下出错信息，出错的部分还不是红字。

然后cc.instantiate(me.MjTile)这里我确定没有返回空，因为用这个已经可以生成prefab并显示出来了。
