Find,FindGameObjectWithTag,FindGameObjectsWithTag三种方式，推荐FindGameObjectsWithTag方式，性能最优。其次是FindGameObjectWithTag，最后是Find
推荐FindGameObjectsWithTag方式返回的GameObject数组。FindGameObjectWithTag和Find返回的是GameObject。

FindGameObjectsWithTag和FindGameObjectsWithTag方式获取的如下的Tag。

实现的功能：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
