Unity登录注册时限制发送验证码次数功能的解决方法

当我们需要在Unity客户端做一个限制功能，比如按钮 （最好是发送验证码按钮）要求每天只能点击三次，等到第二天又有三次机会，这个过程不涉及到服务端消息，只涉及到本地存储，以下是我的解决方案：

直接上代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UniRx;
using System;
using System.IO;
using System.Text;
using System.Globalization;
public class RegisterPanel : MonoBehaviour
  {
    private LoginUIPanel mLoginUIPanel;
    StreamWriter writer;
    StreamReader reader;
 //本地存储手机号
    private string set_phonenum;
 //同一个手机号码使用次数
    private int useNum=1;
    FileInfo file;
    private Button btn_GetMsgCode;

    private Text txt_CountDownTimer;
 
 
}
 private void Awake()
  {
   //获取验证码按钮
      btn_GetMsgCode = input_MsgCode.transform.Find("Btn_GetVerficationCode").GetComponent();
btn_GetMsgCode.onClick.AddListener(OnGetMsgCodeClick);
 txt_CountDownTimer = btn_GetMsgCode.transform.Find("Text").GetComponent();
 
}
 private void onEnable()
    {
 
 ResetGetMsgCode();
}

    private void onGetMsgCodeClick()
    {
     
      if (!mLoginUIPanel.CheckGetMsgCode(input_Account.text))
      {
 Debug.Log("没有输入");
 return;
      }
     
      set_phonenum = input_Account.text.ToString();
 
      if (Limit())
      {
 Debug.Log("返回true");
 return;
      }
      else
      {
 int timer = 60;
 intervalStream = Observable.Interval(TimeSpan.FromSeconds(1))
   .Where(value => { return timer > 1; })
   .SubscribeToText(txt_CountDownTimer, value =>
   {
 
     btn_GetMsgCode.interactable = false;
     
     return (timer--).ToString() + "秒";
   });
 //.AddTo(this);  //绑定生命周期
 
 timeStream = Observable.Timer(TimeSpan.FromSeconds(60))
    .SubscribeToText(txt_CountDownTimer, _ =>
    {
      btn_GetMsgCode.interactable = true;
      return "获取验证码";
    });
 //.AddTo(this);
      }
 
     
    }
 private bool Limit()
    {
      if (PlayerPrefs.HasKey(set_phonenum))
      {
 mLoginUIPanel.ShowToast("号码已经被注册过！");
 return true;
      }
      PlayerPrefs.SetString(set_phonenum, set_phonenum);
      //Application.streamingAssetsPath
 
      //获取当前时间天数
      DateTime now = DateTime.Now;
      DateTimeOffset nowtimesss = DateTimeOffset.Now;
      string nowtime = now.Day.ToString();
      string filenames = Application.dataPath+"/num.txt";
     
      //写入当前次数
      //第一次创建文件
      FileInfo file = new FileInfo(filenames);
      if (!file.Exists)
      {
      
 file.CreateText().Close();
 file.CreationTimeUtc = nowtimesss.UtcDateTime;
 Debug.Log("第一次创建" + file.CreationTimeUtc);
 string bb = file.CreationTime.ToString();
 char[] ss = new char[] {'/'};
 string[] nnn = bb.Split(ss);
 Debug.Log(nnn[1]);
 PlayerPrefs.SetString("FileTime", nnn[1]);
 PlayerPrefs.SetInt("i", 0);
      }
 
    
      if (Convert.ToInt32(nowtime)!=(Convert.ToInt32(PlayerPrefs.GetString("FileTime"))))
      {
 //刷新次数
 Debug.Log("刷新");
 FileStream stream = File.Open(filenames, FileMode.OpenOrCreate, FileAccess.Write);
 stream.Seek(0, SeekOrigin.Begin);
 stream.SetLength(0);
 stream.Close();
 //重置次数和时间
 PlayerPrefs.SetInt("i", 0);
 PlayerPrefs.SetString("FileTime", nowtime);
      }
      //再判断次数
      //如果是当天
      if ((Convert.ToInt32(PlayerPrefs.GetString("FileTime")))== Convert.ToInt32(nowtime))
      {
 Debug.Log("执行");

 
 
 if (PlayerPrefs.GetInt("i") > 2)
 {
   Debug.Log("次数已达上限");
   mLoginUIPanel.ShowToast("次数已达上限，请明天再来！");
 
   return true;
 }
 WriteIntoTxt(useNum, filenames, file);
 //读取本地数据
 ReadOutTxt(filenames);
 //排序
 Allmytxt.Sort();
 //对当前号码取最大值存入
 PlayerPrefs.SetInt("i", Allmytxt[Allmytxt.Count - 1]);
 useNum++;
 int a = 3 - Allmytxt[Allmytxt.Count - 1];
 mLoginUIPanel.ShowToast("今天还剩下"+ a+ "次注册机会");
 Debug.Log(PlayerPrefs.GetInt("i"));
 // Debug.Log("当前文件日期" + Convert.ToInt32(PlayerPrefs.GetString("FileTime")));
 //先判断时间
 return false;
      }
      
      return false;
    }
 
    public void ResetGetMsgCode()
    {
      btn_GetMsgCode.interactable = true;
      txt_CountDownTimer.text = "获取验证码";
    }
 //把所有的数据写入文本中
    public void WriteIntoTxt(int message,string filename,FileInfo file)
    {
 
      // FileInfo file = new FileInfo(filename);
 
      //最后一次修改日期并存储
      
      
 
      if (!file.Exists)
      {
 writer = file.CreateText();
      }
      else
      {
 writer = file.AppendText();
      }
      writer.WriteLine(message);
      writer.Flush();
      writer.Dispose();
      writer.Close();
 
      string bb = file.LastAccessTime.ToString();
      char[] ss = new char[] { '/' };
      string[] nnn = bb.Split(ss);
 
      Debug.Log(nnn[1]);

 PlayerPrefs.SetString("FileTime", nnn[1]);
 
    }
    //读取次数 存储到列表中
    public void ReadOutTxt(string filename)
    {
      Allmytxt.Clear();
      reader = new StreamReader(filename, Encoding.UTF8);
      string text;
      int line = 0;
      while ((text = reader.ReadLine()) != null)
      {
 ++line;
 
// Allmytxt.Add(int.Parse(text));
      }
      //利用文本的行数来判断次数
      Allmytxt.Add(line);
      Debug.Log(line);

}
