苹果出包遇到的问题及解决

1、明明安卓中没问题，但是就是出现疑似某个文件加载不了的问题，解决方法是转成无bom的utf-8文件，以下是抄自网络的文件检测和修改成无bom utf-8格式代码

  1     /// <summary>
  2     /// 遍历检查是否存在并非UTF-8无Bom模式的lua代码
  3     /// </summary>
  4     /// <param name="sSourcePath"></param>

  6 
  7     {
  8         //在指定目录及子目录下查找文件,在list中列出子目录及文件
  9 
 10         DirectoryInfo Dir = new DirectoryInfo(sSourcePath);
 11 
 12         DirectoryInfo[] DirSub = Dir.GetDirectories();
 13 
 14         if (DirSub.Length <= 0)
 15         {
 16 
 17             foreach (FileInfo f in Dir.GetFiles()) //查找文件
 18 
 19             {
 20                 if (!f.Name.EndsWith(".lua"))
 21                 {
 22                     continue;
 23                 }
 24                 FileStream fs = File.OpenRead(f.FullName);
