gameobject上挂载

using UnityEngine;
public class UIInterface : MonoBehaviour
{
    public Object[] compChilds;
}

写wraper

    [LuaCallCSharp]
    public static class UIInterfaceWraper
    {
        //由于lua特性，lua获取到的Object类型，可以直接调用其具体类型的属性方法
        //但是，如果要调用C#方法，必须使用具体类型
        //比如这个，需通过wraper方法
        public static void ForceRebuildLayoutImmediate(Object obj)
        {
            LayoutRebuilder.ForceRebuildLayoutImmediate(obj as RectTransform);
        }
        public static Object GetUnityEngineObject(UIInterface face,int index)
        {
           return face.pChilds[index];
        }
    }

lua中这样获取

local getUEObject =function (index,face)
    return face.compChilds[index]
end

local face = self.container:GetComponent("UIInterface")
self.obj1 = getUEObject(0, face)
self.scrollRect = getUEObject(1, face)--获取Object类型，可直接在lua'中当作对应类型处理
self.content = getUEObject(2, face)

CS.UIInterfaceWraper.ForceRebuildLayoutImmediate(self.content)

ui组件自动获取（editor代码）

    public static void AddComp()
    {
        GameObject window = Selection.activeGameObject;
        if (window == null)
            return;

        UIInterface face = window.GetComponent<UIInterface>();
        if (face == null)
        {
            face = window.AddComponent<UIInterface>();
        }
        AllList = new List<Object>();

        AddToList(face.transform);

        face.pChilds = new Object[AllList.Count];
        for (int i = 0; i < AllList.Count; i++)
        {
            face.pChilds[i] = AllList[i];
        }
        EditorUtility.SetDirty(window);
        //AssetDatabase.SaveAssets();
    }
    static void AddToList(Transform transform)
    {
        foreach (Transform item in transform)
        {
            var obj = GetObj(item.gameObject);
            if (obj != null)
            {
                AllList.Add(obj);
            }

            if (item.childCount > 0 && item.GetComponent<UIInterface>() == null)
                AddToList(item);
        }
    }
public static UnityEngine.Object GetObj(GameObject tgo)
    {
        int length = tgo.gameObject.name.Length;
        if (length <= 3)
            return null;

        string n = tgo.name.Remove(3);
        UnityEngine.Object obj = null;
        switch (n)
        {
            case "txt":
                obj = tgo.GetComponent<TextMeshProUGUI>();
                break;
            case "btn":
                obj = tgo.GetComponent<Button>();
                break;
            case "obj":
                obj = tgo;
                break;
            case "tra":
                obj = tgo.transform;
                break;
            case "rct":
                obj = tgo.transform as RectTransform; 
                break;
            case "ins":
                obj = tgo.GetComponent<UIInterface>();
                break;
            case "sdr":
                obj = tgo.GetComponent<Slider>();
                break;
            case "tog":
                obj = tgo.GetComponent<Toggle>();
                break;
            case "inp":
                obj = tgo.GetComponent<InputField>();
                break;
            case "slr":
                obj = tgo.GetComponent<ScrollRect>();
                break;
            case "cvg":
                obj = tgo.GetComponent<CanvasGroup>();
                break;
            default:
                // Log.Error("未能处理物体:", tgo.name);
                break;
        }
        return obj;
    }

ui代码生成 （editor代码）

    private static string upperFirst(string s)
    {
        return Regex.Replace(s, @"\b[a-z]\w+", delegate (Match match)
        {
            string v = match.ToString();
            return char.ToUpper(v[0]) + v.Substring(1);
        });
    }
    private static string GenCode()
{
         GameObject window = Selection.activeGameObject;
        if (window == null)
            return;
        UIInterface face = window.GetComponent<UIInterface>();
        var list = face.pChilds;
        string line = "--UI Members " + "\n";
        int index = 0;
        foreach (var obj in list)
        {
            string Goanme = string.Empty;
            GameObject go = null;
            if (obj is GameObject)
            {
                go = obj as GameObject;
                Goanme = go.name;
            }
            else if (obj is Component com)
            {
                Goanme = com.transform.gameObject.name;
            }
            string start = Goanme.Remove(3);
            string name = "self.m" + upperFirst(Goanme).Replace(" ","");
            if (!string.IsNullOrEmpty(Goanme))
            {
                line += name+ "=Utils.GetUnityEngineObject(" +index+",face)\n";
            }
            index++;
        }
       Debug.Log(line);
}

效果

--UI Members 
self.mSlrScrollView=Utils.GetUnityEngineObject(0,face)
self.mSdrSlider=Utils.GetUnityEngineObject(1,face)
self.mBtnButton=Utils.GetUnityEngineObject(2,face)
