Enable or Disable Iphone Push Notifications inside the app

Question

I have a iphone app which is enable to receive push notifications. Currently i can disable push notifications for my app by going to the iphone settings/Notifications.

Answer 1

Pragmatically, it is possible to enable & disable push notification by registering and unregistering push notification.

Enable Push Notification:

if #available(iOS 10.0, *) {
   // 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{
    // Below iOS 10.0

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

    //or
    //UIApplication.shared.registerForRemoteNotifications()
}

Delegate methods

@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) {
    // .. Receipt of device token
}


func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    // handle error
}

Disable Push Notification:

UIApplication.shared.unregisterForRemoteNotifications()
