當(dāng)我們需要在Unity客戶端做一個限制功能,比如按鈕 (最好是發(fā)送驗證碼按鈕)要求每天只能點擊三次,等到第二天又有三次機(jī)會,這個過程不涉及到服務(wù)端消息,只涉及到本地存儲,以下是我的解決方案:
直接上代碼:
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; //本地存儲手機(jī)號 private string set_phonenum; //同一個手機(jī)號碼使用次數(shù) private int useNum=1; FileInfo file; private Button btn_GetMsgCode; /**倒計時 */ private Text txt_CountDownTimer; } private void Awake() { //獲取驗證碼按鈕 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(); } /** * 獲取驗證碼 */ private void OnGetMsgCodeClick() { if (!mLoginUIPanel.CheckGetMsgCode(input_Account.text)) { Debug.Log("沒有輸入"); 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); //綁定生命周期 timeStream = Observable.Timer(TimeSpan.FromSeconds(60)) .SubscribeToText(txt_CountDownTimer, _ => { btn_GetMsgCode.interactable = true; return "獲取驗證碼"; }); //.AddTo(this); } } private bool Limit() { if (PlayerPrefs.HasKey(set_phonenum)) { mLoginUIPanel.ShowToast("號碼已經(jīng)被注冊過!"); return true; } PlayerPrefs.SetString(set_phonenum, set_phonenum); //Application.streamingAssetsPath //獲取當(dāng)前時間天數(shù) DateTime now = DateTime.Now; DateTimeOffset nowtimesss = DateTimeOffset.Now; string nowtime = now.Day.ToString(); string filenames = Application.dataPath+"/num.txt"; //寫入當(dāng)前次數(shù) //第一次創(chuàng)建文件 FileInfo file = new FileInfo(filenames); if (!file.Exists) { file.CreateText().Close(); file.CreationTimeUtc = nowtimesss.UtcDateTime; Debug.Log("第一次創(chuàng)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")))) { //刷新次數(shù) Debug.Log("刷新"); FileStream stream = File.Open(filenames, FileMode.OpenOrCreate, FileAccess.Write); stream.Seek(0, SeekOrigin.Begin); stream.SetLength(0); stream.Close(); //重置次數(shù)和時間 PlayerPrefs.SetInt("i", 0); PlayerPrefs.SetString("FileTime", nowtime); } //再判斷次數(shù) //如果是當(dāng)天 if ((Convert.ToInt32(PlayerPrefs.GetString("FileTime")))== Convert.ToInt32(nowtime)) { Debug.Log("執(zhí)行"); if (PlayerPrefs.GetInt("i") > 2) { Debug.Log("次數(shù)已達(dá)上限"); mLoginUIPanel.ShowToast("次數(shù)已達(dá)上限,請明天再來!"); return true; } WriteIntoTxt(useNum, filenames, file); //讀取本地數(shù)據(jù) ReadOutTxt(filenames); //排序 Allmytxt.Sort(); //對當(dāng)前號碼取最大值存入 PlayerPrefs.SetInt("i", Allmytxt[Allmytxt.Count - 1]); useNum++; int a = 3 - Allmytxt[Allmytxt.Count - 1]; mLoginUIPanel.ShowToast("今天還剩下"+ a+ "次注冊機(jī)會"); Debug.Log(PlayerPrefs.GetInt("i")); // Debug.Log("當(dāng)前文件日期" + Convert.ToInt32(PlayerPrefs.GetString("FileTime"))); //先判斷時間 return false; } return false; } /** * reset重置倒計時· */ public void ResetGetMsgCode() { btn_GetMsgCode.interactable = true; txt_CountDownTimer.text = "獲取驗證碼"; } //把所有的數(shù)據(jù)寫入文本中 public void WriteIntoTxt(int message,string filename,FileInfo file) { // FileInfo file = new FileInfo(filename); //最后一次修改日期并存儲 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]); } //讀取次數(shù) 存儲到列表中 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)); } //利用文本的行數(shù)來判斷次數(shù) Allmytxt.Add(line); Debug.Log(line); reader.Dispose(); reader.Close(); }
