Answer 1

you can register and unregister the remote notification with bellow code.

Register RemoteNotification with bellow code..means Enable notification

//-- 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)]; } 

and Disable it with bellow code.

[[UIApplication sharedApplication] unregisterForRemoteNotifications];

Swift 4

Enable Push Notification (Setup from app):

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()
}

Delegate methods to handle push notifications

@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)
}

Disable Push Notifiacation:

UIApplication.shared.unregisterForRemoteNotifications()
