问题：预制体的文本在Inspector直接用\n换行不生效

原因：因为unity会默认把\n替换成\\n

问题：预制体的文本在Inspector直接用\n换行不生效

        预制体文本用换行符直接换好，如果要用代码替换换行，使用\n换行没有生效。

原因：因为unity会默认把\n替换成\\n

        需要把\\n替换成\n，以下是我写的一个替换工具

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

/// <summary>
/// prefab文本换行替换
/// </summary>
public class PrefabNewLineEditor:EditorWindow
{
    private static string PREFAB_PATH = "Assets/Prefab";

    [MenuItem("Tools/UI/文本换行替换")]
    public static void PrefabNewLineText() 
    {
        string[] allPath = AssetDatabase.FindAssets("t:Prefab",new string[] { PREFAB_PATH } );

        for (int i = 0; i < allPath.Length; i++)
        {
            string path = AssetDatabase.GUIDToAssetPath(allPath[i]);
            var obj = PrefabUtility.InstantiatePrefab(AssetDatabase.LoadAssetAtPath(path, typeof(GameObject))) as GameObject ;
            if (obj != null)
            {
                var texts = obj.GetComponentsInChildren<Text>(true);
                foreach (Text text in texts) 
                {
                    text.text = text.text.Replace("\\n", "\n");
                }
            }
            PrefabUtility.SaveAsPrefabAsset(obj, path);
            GameObject.DestroyImmediate(obj);
        }
        AssetDatabase.SaveAssets();
        AssetDatabase.Refresh();
    }
}
