Unity 定时发送通知

unity.jpeg

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_ANDROID
using 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[i]);
            // }
        }
     
    }
    
    /// <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_IOS
using 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[i]);
            // }
        }
     
    }
    
    /// <summary>
    /// 发送通知方法
    /// </summary>
    /// <param name="title"></param>
    /// <param name="text"></param>

    /// <param name="second"></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");
    }
