Unityで特定の日時にローカル通知する

はじめに

Unity Mobile Notifications Package
こちらのiOS/Androidでプッシュ通知を実装できるパッケージを使ってiOSのプッシュ通知を行います。

インストール

『Package Manager』から『Mobile Notifications』をインストールします。

#使い方
今回は2020年1月1日20時20分に通知を送る設定にしてます。
特定の日時に送る場合は『iOSNotificationCalendarTrigger』を参照します。

PushTest.cs

using System.Collections;
using System.Collections.Generic;
using Unity.Notifications.iOS;
using UnityEngine;
using System;

public class PushScript : MonoBehaviour
{

    // Start is called before the first frame update
    void Start()
    {

    }

    IEnumerator RequestAuthorization()
    {
        using (var req = new AuthorizationRequest(AuthorizationOption.Alert | AuthorizationOption.Badge, true))
        {
            while (!req.IsFinished)
            {
                yield return null;
            }

            string res = "\n RequestAuthorization: \n";
            res += "\n finished: " + req.IsFinished;
            res += "\n granted :  " + req.Granted;
            res += "\n error:  " + req.Error;
            res += "\n deviceToken:  " + req.DeviceToken;
            Debug.Log(res);
        }

    }
    
    // ボタンが押された際に呼び出される関数
    public void OnClickBtn()
    {
        var calendarTrigger = new iOSNotificationCalendarTrigger()
        {
            Year = 2020,
            Month = 1,
            Day = 1,
            Hour = 20,
            Minute = 20,
            Repeats = false
        };

        var notification = new iOSNotification()
        {
            // You can optionally specify a custom identifier which can later be 
            // used to cancel the notification, if you don't set one, a unique 
            // string will be generated automatically.
            Identifier = "_notification_01",
            Title = "Title",
            Body = "Scheduled at: 2020年1月1日20時20分",
            Subtitle = "This is a subtitle, something, something important...",
            ShowInForeground = true,
            ForegroundPresentationOption = (PresentationOption.Alert | PresentationOption.Sound),
            CategoryIdentifier = "category_a",
            ThreadIdentifier = "thread1",
            Trigger = calendarTrigger,
        };

        iOSNotificationCenter.ScheduleNotification(notification);
    }
}
