iOS.LocalNotification は、Apple UIKit フレームワークにある UILocalNotification クラス周辺のラッパーです。これは、iPhone/iPad/iPod Touch でのみ利用できます。
It represents notifications that an application can schedule for presentation to its user at specific dates and times.
The operating system is responsible for delivering the notification at the specified time.
Local notifications are similar to remote notifications but are scheduled and delivered locally and do not require connection with remote servers.
ローカル通知は NotificationServices クラスを使用して処理されます。
The iOS Notification Services API is deprecated and will be removed in a future version of Unity. Please consider using the the "Mobile Notifications" package (available in the Unity package manager) which implements the iOS UserNotifications framework.
