Как включить/отключить push-уведомление из приложения?

Ответ 1

вы можете зарегистрировать и отменить регистрацию удаленного уведомления с помощью следующего кода.

Зарегистрировать RemoteNotification с помощью следующего кода..means Включить уведомление

//-- Set Notification
if ([[UIApplication sharedApplication]respondsToSelector:@selector(isRegisteredForRemoteNotifications)])
{
    // For iOS 8 and above
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];

    [[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
    // For iOS < 8
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}

и отключить его с помощью следующего кода.

[[UIApplication sharedApplication] unregisterForRemoteNotifications];

Включить Push Notification (Настройка из приложения):

if #available(iOS 10.0, *) {

   // SETUP FOR NOTIFICATION FOR iOS >= 10.0
   let center  = UNUserNotificationCenter.current()
   center.delegate = self
   center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
         if error == nil{
            DispatchQueue.main.async(execute: {
               UIApplication.shared.registerForRemoteNotifications()
            }) 
         }
   }

} else {

   // SETUP FOR NOTIFICATION FOR iOS < 10.0

   let settings = UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)
   UIApplication.shared.registerUserNotificationSettings(settings)

   // This is an asynchronous method to retrieve a Device Token
   // Callbacks are in AppDelegate.swift
   // Success = didRegisterForRemoteNotificationsWithDeviceToken
   // Fail = didFailToRegisterForRemoteNotificationsWithError
    UIApplication.shared.registerForRemoteNotifications()
}

Делегировать методы для обработки push-уведомлений

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

}

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

}


func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    // ...register device token with our Time Entry API server via REST
}


func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    //print("DidFaildRegistration : Device token for push notifications: FAIL -- ")
    //print(error.localizedDescription)
}

Отключить Push Notifiacation:

UIApplication.shared.unregisterForRemoteNotifications()
