根据网上的资料进行整合改整了下

使用线程刷

生成的文件在 persistentDataPath目录下

    /// 也可以手动控制这个手动启动
    /// </summary>

    {
        mLogLock = new object();
        //Application.persistentDataPath Unity中只有这个路径是既可以读也可以写的。
        outpath = Application.persistentDataPath + "/outLog.txt";
        //每次启动客户端删除之前保存的Log
        if (System.IO.File.Exists(outpath))
        {
            File.Delete(outpath);
        }
        //在这里做一个Log的监听(老方法,已弃用)
        //Application.RegisterLogCallback(HandleLog);

        //用线程刷
        Application.logMessageReceivedThreaded += HandleLog;
        this.mFileLogThread = new Thread(new ThreadStart(WriteLog));

        //一个输出
