Unity实现简易日志输出功能

在使用Unity中的Debug.Log()进行日志输出时很不方便，在打包出来的可执行文件中没有办法看到输出，所有就想自己实现一个简易的日志输出功能，可以输出到日志文件，因为能力实在是不够，所以有错误和不合理的地方，还请各位老师指点一下，谢谢啦

1.日志记录器接口

public interface ILogger
{
void Log(string condition, string stackTrace, UnityEngine.LogType type);
}

2.日志文件记录器

using System;
using UnityEngine;
using System.IO;

public class FileLogger : ILogger
{
private readonly string path;

/// <summary>
/// 构造方法
/// </summary>
/// <param name="isClear">是否清空原有的日志</param>
public FileLogger(bool isClear = false)
{
 switch (Application.platform)
 {
  case RuntimePlatform.Android:
   path = Path.Combine( Application.persistentDataPath,"log.txt");
   break;
  case RuntimePlatform.WindowsPlayer:
   path = Path.Combine(Application.dataPath, "log.txt");
   break;
  case RuntimePlatform.WindowsEditor:
   path = Path.Combine(Application.dataPath, "log.txt");
   break;
  case RuntimePlatform.IPhonePlayer:
   path = Path.Combine(Application.persistentDataPath, "log.txt");
   break;
  case RuntimePlatform.OSXEditor:
   break;
  default:
   break;
 }

if (isClear)
 {
  if (File.Exists(path))
  {
   File.Delete(path);
  }
 }
}

public void Log(string condition, string stackTrace, LogType type)
{
 using (StreamWriter sw = new StreamWriter(path, true, System.Text.Encoding.UTF8))
 {
  string msg = string.Format("[{0}] {1}: {2}\n{3}", GetNowTime(), type, condition, stackTrace);
  sw.WriteLine(msg);
 }
}

#region Tool Method
private string GetNowTime()
{
 return DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");
}
#endregion
}

3.日志系统管理类 

using System;
using UnityEngine;

public class LogSys
{
private static ILogger logger;
public static ILogger Logger
{
 get { return logger; }
}

public bool IsOpen
{
 get { return Debug.unityLogger.logEnabled; }
}

private LogSys() { }

/// <summary>
/// 初始化
/// </summary>
/// <param name="_logger">日志输出器</param>
/// <param name="isOpen">是否开启日志输出</param>
public static void Init(ILogger _logger, bool isOpen = true)
{
 Init(isOpen);
 logger = _logger;
 Enable();
}

public static void Init(bool isOpen = true)
{
 Debug.unityLogger.logEnabled = isOpen;
}

/// <summary>
/// 过滤器
/// </summary>
/// <param name="logType">需要显示的日志类型</param>
public static void Filter(LogType logType = LogType.Log)
{
 Debug.unityLogger.filterLogType = logType;
}

public static void Enable()
{
 if (logger != null)
 {
  Application.logMessageReceived += logger.Log;
 }
}

public static void Disable()
{
 if (logger != null)
 {
  Application.logMessageReceived -= logger.Log;
 }

}
}

4.测试 

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

public class Test : MonoBehaviour
{
public Text logText;

void Awake()
{
 LogSys.Init(new FileLogger());
}

void Update()
{
 if (Input.GetKeyDown(KeyCode.Q))
 {
  Debug.Log("My name is Blinkedu.");
 }

if (Input.GetKeyDown(KeyCode.W))
 {
  Debug.LogWarning("My name is Blinkedu.");
 }

if (Input.GetKeyDown(KeyCode.E))
 {
  Debug.LogError("My name is Blinkedu.");
 }
}

private void OnDestroy()
{
 LogSys.Disable();
}
}
