私は通知を勉強しています。スケジュールを作成するためにdatePickerを使用して通知を表示するコードを作成します。コードはうまくいきました。 しかし、私のアプリがバックグラウンドになってから10分ごとに通知を表示する方法はありますか？ これは私のコードをOS：通知についてiOS
AppDelegate：
func application(application: UIApplication, didRegisterUserNotificationSettings notificationSettings: UIUserNotificationSettings) {
print(notificationSettings.types.rawValue)
}
func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
print("Received Local Notification:")
print(notification.alertBody!)
}
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler:() -> Void) {
if identifier == "editList" {
NSNotificationCenter.defaultCenter().postNotificationName("modifyListNotification", object: nil)
}
else if identifier == "trashAction" {
NSNotificationCenter.defaultCenter().postNotificationName("deleteListNotification", object: nil)
}
completionHandler()
}

アプリが終了すると通知をスケジュールできません。あなたのアプリが実行状態にあるときだけ表示するように設定してください – Shubhank
