详细报错信息，包含调用堆栈：
Uncaught TypeError: this._sgNode.getTexture is not a function

重现方式：
let tlayer = children[i].getComponent(cc.TiledLayer);
if(tlayer){
let tex = tlayer.getTexture();
} -
出现概率：必现
好像是CCTiledLayer.js提供了getTexture这个方法
当跟到方法里
getTexture: function(){
if (this._sgNode) {
return this._sgNode.getTexture();
}
return null;
}
this._sgNode下没有getTexture这个方法就报错了
