//游戏上线之前把LogHelper.m_logLevel = LogLevel.None;Log就不显示了。
//LogHelper.m_logLevel = LogLevel.Error;是显示Error。
//LogHelper.m_logLevel = LogLevel.Debug | LogLevel.Error;同时显示Debug和Error。
//private string m_logPath = Environment.CurrentDirectory + "/log/";
//log文件是保存在 private string m_logPath = Application.persistentDataPath + "/log/";在手机上就是沙盒路径。
//log文件是以天为单位，同一天的log会被记录到一个文件里面。
