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;
/**倒计时 */
    private text txt_countdowntimer;
 
 
}
 private void awake()
  {
   //获取验证码按钮
      btn_getmsgcode = input_msgcode.transform.find("btn_getverficationcode").getcomponent<button>();
btn_getmsgcode.onclick.addlistener(ongetmsgcodeclick);
 txt_countdowntimer = btn_getmsgcode.transform.find("text").getcomponent<text>();
 
}
 private void onenable()
    {
 
 resetgetmsgcode();
}
/**
     * 获取验证码 
     */
    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
