   let sliderImageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 30))
    sliderImageView.contentMode = .ScaleAspectFit
    sliderImageView.image = UIImage(named: "sliderMenu")

    var sliderImage = UIImage(named: "sliderMenu")
    navigationItem.leftBarButtonItem?.image = sliderImage
