iospush-notificationdevicetoken

get device token without enter to the function didRegisterForRemoteNotificationsWithDeviceToken

I have in the settings page a button to let the user enable or disable the push notification.

If the user doesn't allow to receive push notification the first time he launch the application, how can I get the Device Token if the user turn on the notification setting later in setting page?

Thanks.

Solution

  • No its not possible , when user authenticate the allow permission and run your project , it automatically call the method didRegisterForRemoteNotificationsWithDeviceToken else it call the didFailToRegisterForRemoteNotificationsWithError

    - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:
(NSData *)deviceToken {

NSString* deviceTokene = [[[[deviceToken description]
                            stringByReplacingOccurrencesOfString: @"<" withString: @""]
                           stringByReplacingOccurrencesOfString: @">" withString: @""]
                          stringByReplacingOccurrencesOfString: @" " withString: @""] ;



NSLog(@"%@",deviceTokene);


}

    this is the coding to enable the APNS in Viewcontroller

      UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge
                                                                                             |UIUserNotificationTypeSound
                                                                                             |UIUserNotificationTypeAlert) categories:nil];
        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];

    if you want to disable the APNS in inside the VC 

     [[UIApplication sharedApplication] unregisterForRemoteNotifications];
