Swift ローカル通知

ローカル通知を設定　

viewController.swift

import UserNotification

//通知のタイトルと内容を設定
let content = UNMutableNotificationContent()
content.title = "(タイトル)"
content.body = "(内容)"
content.sound = UNNotificationSound.default() //通知音

//通知する日付を設定
let date:Date = (通知したい日付)
let calendar = Calendar.current()
let dateComponent = calendar.dateComponents([.year, .month, .day, .hour, minute] , from: date)

//以上の通知をリクエストに指定
let trigger = UNCalendarNotificationTrigger.init(dateMatching: dateComponent, repeats: false)
let request = UNNotificationRequest.init(identifier: "一意の値", content: content,//UNMutableNotificationContent trigger: trigger //UNNotificationTrigger)

//通知を設定
let center = UNNotificationCenter.current()
center.add(request, completion: nil)

ユーザーへローカル通知の許諾の通知

AppDelegate.swift

import UserNotification

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
        // Override point for customization after application launch.
        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options: [.alert,.sound]){(granted, error) in

        }

        center.delegate = self;
        return true
    }

またアプリ起動中でもローカル通知を表示させるためのコード

AppDelegate.swift

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.sound, .alert])
    }
