Not showing on pushview

` let cartBarButton: UIBarButtonItem = UIBarButtonItem(title: "Test", style: UIBarButtonItemStyle.Plain, target: self, action: nil)//#selector(self.toggleLeft))
let attributes = [NSFontAttributeName: UIFont.fontAwesomeOfSize(25)] as Dictionary!
cartBarButton.setTitleTextAttributes(attributes, forState: .Normal)
cartBarButton.title = String.fontAwesomeIconWithName(.ShoppingCart)
cartBarButton.tintColor = CommonMainColor
self.navigationItem.rightBarButtonItem = cartBarButton

    let hub:RKNotificationHub = RKNotificationHub(barButtonItem: cartBarButton)
    hub.increment()
    hub.count = 90
    hub.setCircleAtFrame(CGRectMake(15, -5, 20, 20))
    **hub.pop()`**

Found a solution. Use this

let imgView = UIImageView(image: UIImage(named: "ico_cart"))
self.btncart.customView = imgView
        
self.hub = RKNotificationHub(view: imgView)

 //additionally use these methods
self.hub?.scaleCircleSize(by: 0.7)
self.hub?.moveCircleBy(x: 5, y: 0)
