这里用到的插件是Pakeage Manager中的Moblie Notification。

建议用推荐版本version1.0.3，下载成功之后，Package包下会自动生成如下图：

创建一个NotificationSender

控制不同平台下，使用AndroidNotificationSender和iOSNotificationSender。
public class NotificationInfo{ public string title; public string text; public int day; public int hour; public int minute; public int second; public string smallIcon; public string largeIcon;}public class NotificationSender:#if UNITY_ANDROID AndroidNotificationSender#else    iOSNotificationSender#endif{ private void OnApplicationFocus(bool hasFocus) {       if(hasFocus)          ReSendNotification(); } /// <summary> /// 得到注册通知的时间 /// </summary> /// <returns></returns> public static DateTime GetNotificationTime(NotificationInfo notificationInfo) {       var daySpan = new TimeSpan(notificationInfo.day,notificationInfo.hour,notificationInfo.minute,notificationInfo.second);       var dateTime = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second) ;       dateTime += daySpan;       if (dateTime.Hour >= 23)       {          dateTime += new TimeSpan(9, 0, 0);       }       if (dateTime.Hour <= 8)       {          dateTime += new TimeSpan(8 - dateTime.Hour, 0, 0);       }       // Debug.Log("LinneaNotify 发出通知时间 : " + dateTime);       return dateTime; }}
限制了通知时间，不得23点之后和8点之前发出。
Android平台代码：

#if  UNITY_ANDROIDusing System;using System.Collections.Generic;using Unity.Notifications.Android;using UnityEngine;public class AndroidNotificationSender:MonoBehaviour{ private static bool _isInitialized; private static List<NotificationInfo> _notificationInfos; private static int _notificationId = 19991; private static void Init() {       if(_isInitialized)          return;       _notificationInfos = new List<NotificationInfo>();       ResetNotificationChannel();       var notificationGo= new GameObject("NotificationBehaviour").AddComponent<NotificationSender>();       DontDestroyOnLoad(notificationGo);       _isInitialized = true; } private static void ResetNotificationChannel() {       _notificationId = 19991;       AndroidNotificationCenter.CancelAllNotifications();//清除上次注册的通知       var channel = new AndroidNotificationChannel()       {          Id = "channel_id",          Name = "Default Channel",          Importance = Importance.High,          Description = "Generic notifications",          CanShowBadge = true,          EnableLights=true,          LockScreenVisibility=LockScreenVisibility.Public       };             AndroidNotificationCenter.RegisterNotificationChannel(channel); } protected static void ReSendNotification() {       if (_isInitialized && _notificationInfos != null && _notificationInfos.Count > 0)       {          ResetNotificationChannel();          // for (var i = 0; i < _notificationInfos.Count; i++)          // {          //    SendNotification(_notificationInfos);          // }       }       }       /// <summary> /// Android 发送通知 /// </summary> /// <param name="title"></param> /// <param name="text"></param> /// <param name="day"></param> /// <param name="hour"></param> /// <param name="minute"></param> /// <param name="second"></param> /// <param name="smallIconId"></param> /// <param name="largeIconId"></param> public static void SendNotification(string title, string text,int day,int hour,int minute,int second ,string smallIconId=null,string largeIconId=null) {       Init();       var notificationInfo = new NotificationInfo()       {          title = title,          text = text,          day = day,          hour = hour,          minute = minute,          second = second,          smallIcon = smallIconId,          largeIcon = largeIconId       };       _notificationInfos.Add(notificationInfo);       SendNotification(notificationInfo); }       private static void SendNotification(NotificationInfo notificationInfo)//string title, string text,DateTime time,string smallIconId=null,string largeIconId=null) {       var time = NotificationSender.GetNotificationTime(notificationInfo);       var notification = new AndroidNotification(){          Title = notificationInfo.title,          Text = notificationInfo.text,          FireTime = time,          SmallIcon = notificationInfo.smallIcon,          LargeIcon = notificationInfo.largeIcon,          Number = _notificationId       };       AndroidNotificationCenter.CancelNotification(_notificationId);       _notificationId++;       AndroidNotificationCenter.SendNotification(notification, "channel_id"); }}#endif
注意ReSendNotification方法，因为我在外部限制通知每次发出先判断上次是否还有通知未发出，所以屏蔽了ReSend方法。
IOS平台代码：

#if  UNITY_IOSusing System;using System.Collections;using System.Collections.Generic;using UnityEngine;using Unity.Notifications.iOS;public class iOSNotificationSender:MonoBehaviour{    private static bool _isInitialized = false;    private static int _notificationId = 1;    private static List<NotificationInfo> _notificationInfos; // Start is called before the first frame update private static void Init() {       if(_isInitialized)          return;       _notificationInfos = new List<NotificationInfo>();       ResetNotificationChannel();       var notificationGo= new GameObject("NotificationBehaviour").AddComponent<NotificationSender>();       DontDestroyOnLoad(notificationGo);       _isInitialized = true; } private static void ResetNotificationChannel() {       _notificationId = 1;       iOSNotificationCenter.ApplicationBadge=0;       iOSNotificationCenter.RemoveAllDeliveredNotifications();       iOSNotificationCenter.RemoveAllScheduledNotifications(); } protected static void ReSendNotification() {       if (_isInitialized&&_notificationInfos!=null && _notificationInfos.Count > 0)       {          ResetNotificationChannel();          // for (var i = 0; i < _notificationInfos.Count; i++)          // {          //    SendNotification(_notificationInfos);          // }       }       }       /// <summary> /// 发送通知方法 /// </summary> /// <param name="title"></param> /// <param name="text"></param> /// <param name="day"></param> /// <param name="hour"></param> /// <param name="minute"></param> /// <param name="second"></param> /// <param name="smallIconId"></param> /// <param name="largeIconId"></param> public static void SendNotification(string title, string text,int day,int hour,int minute,int second ,string smallIconId=null,string largeIconId=null) {       Init();             var notificationInfo = new NotificationInfo()       {          title = title,          text=text,          day=day,          hour = hour,          minute = minute,          second = second,          smallIcon = smallIconId,          largeIcon = largeIconId       };       _notificationInfos.Add(notificationInfo);       SendNotification(notificationInfo); }    private static void SendNotification(NotificationInfo notificationInfo)//string title, string text,TimeSpan timeInterval) {             var time = NotificationSender.GetNotificationTime(notificationInfo);       var timeInterval = time.Subtract(DateTime.Now);             var timeTrigger = new iOSNotificationTimeIntervalTrigger()       {          TimeInterval = new TimeSpan(timeInterval.Days, timeInterval.Hours, timeInterval.Minutes, timeInterval.Seconds),// timeInterval,          Repeats = false       };             var notification = new iOSNotification()       {          Identifier = "_notification_"+ _notificationId,          Title = notificationInfo.title,          Body = notificationInfo.text,          Badge = _notificationId,          ShowInForeground = true,          ForegroundPresentationOption = (PresentationOption.Alert | PresentationOption.Sound | PresentationOption.Badge),          CategoryIdentifier = "category_a",          ThreadIdentifier = "thread1",          Trigger = timeTrigger,       };       _notificationId++;       iOSNotificationCenter.ScheduleNotification(notification); } }#endif
注意_notificationId，这里的id实际上是显示在AppIcon的红点数字

我的调用处理，在程序退出后台后，判断是否达到条件，是否要发出通知：
/// <summary> ///  isPause /// </summary> private static bool isPause; private static bool isSendNearNotify; private static bool isSendFarNotify; private void OnApplicationPause(bool pauseStatus) {       isPause = pauseStatus;       if (isPause)       {          JudgeNearNotify();          JudgeFarNotify();       }       else       {          isSendNearNotify = false;          isSendFarNotify = false;       } }
发出一条近期带活通知：
private static void JudgeNearNotify() {       if (!isPause || isSendNearNotify) return;       isSendNearNotify = true;       var title = LocalizationManager.GetTranslation("notify_title1");       var text = LocalizationManager.GetTranslation("notify_content1");       var time1 = OfflineEquipment.Instance.GetNotifyOfflineTime();       var time2 = CropManager.Instance.GetNotifyCropTime();       var max = time1;       // Debug.Log("LinneaNotify time1 = " + time1 + ", time2 = " + time2);       if (time2 > time1)       {          title = LocalizationManager.GetTranslation("notify_title2");          text = LocalizationManager.GetTranslation("notify_content2");          max = time2;       }       if (max > 0)       {          var day = max / 60 / 60 / 24;          var hour = max / 60 / 60 % 24;          var minute = max / 60 % 60;          var second = max % 60;          // Debug.Log("LinneaNotify day = " + day + ", hour = " + hour + ", minute = " + minute + ", sec = " + second);          NotificationSender.SendNotification(title, text,  day, hour, minute, second, "icon_large");       } }
发出一条远期带活通知：
/// <summary> /// 长期不在线拉活 /// </summary> private static void JudgeFarNotify() {       if (!isPause || isSendFarNotify) return;       isSendNearNotify = true;       var title = LocalizationManager.GetTranslation("notify_title3");       var text = LocalizationManager.GetTranslation("notify_content3");       NotificationSender.SendNotification(title, text, 3, 0, 0, 0, "icon_large"); }
