本文介绍如何在Unity编辑器中批量为所有Prefab添加PrefabInfoHelper组件。通过MenuItem函数`AddPrefabInfoHelper`，遍历选择的深资产对象，检查是否为Prefab，然后实例化Prefab，添加PrefabInfoHelper组件，设置相关信息，并使用PrefabUtility替换Prefab，最后销毁临时实例。

[MenuItem("所有Prefab添加PrefabInfoHerlper组件")]
    static void AddPrefabInfoHelper()
    {
        UnityEngine.Object[] selObjs = Selection.GetFiltered(typeof(UnityEngine.Object), SelectionMode.DeepAssets);
        for (int i = 0; i < selObjs.Length; i++)
        {
            Object selObj = selObjs[i];
            string selfPath = AssetDatabase.GetAssetPath(selObj);
            if (selfPath.EndsWith(".prefab"))
            {
                string[] dependPaths = AssetDatabase.GetDependencies(selfPath);
                GameObject go = GameObject.Instantiate(selObj) as GameObject;
                
                PrefabInfoHelper pih = go.GetComponent<PrefabInfoHelper>();
                if (pih == null)
                {
                    pih = go.AddComponent<PrefabInfoHelper>();
                }
                pih.isInstanced = false;
                pih.selfPath = selfPath;
                pih.dependPathList.Clear();
