Try this for Objective-C:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions

  {
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound) categories:nil];
    [application registerUserNotificationSettings:settings];
  } 
else // iOS 7 or earlier
  {
    UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
    [application registerForRemoteNotificationTypes:myTypes];
  }
}

For Swift:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
// Override point for customization after application launch.
 if(UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:")))
 {
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: UIUserNotificationType.Sound | UIUserNotificationType.Alert | UIUserNotificationType.Badge, categories: nil))
 }
 else
 {
    //
 }
return true
}
