为了方便用代码创建UGUI，封装了一个工厂类，写了一点，后续有空再添加没有添加的组件的封装

代码如下：

using UnityEngine;using UnityEngine.UI;using System.Collections;using System.Collections.Generic;using System;public class UGUIFactory{    public static GameObject CreateImage(GameObject parent, string name, string sprName, Vector3 pos)    {        GameObject go = AddChild(parent, name);        go.transform.localPosition = pos;        go.transform.localScale = Vector2.one;        var image = go.AddComponent();        image.sprite = getSpriteByName(sprName);        var rectTrans = go.GetComponent
   
    ();        image.SetNativeSize();        return go;    }    public static GameObject CreateImage(GameObject parent, string name, string sprName,Vector3 pos,Vector2 size)    {        GameObject go = AddChild(parent, name);        go.transform.localPosition = pos;        var image = go.AddComponent
