issue with image

[rogomantik]

when setting an image the rippleBackgroundColor is drawn above the image and the rippleColor above the rippleBackgroundColor
I had to set rippleBackgroundColor to clear (remains the backgroundcolor) and the rippleColor with an alpha component < 1

        buttonSelect.backgroundColor = UIColor.redColor
        buttonSelect.rippleBackgroundColor = UIColor.clearColor() //or color with low alpha
        buttonSelect.rippleColor = redColor().lightenColor().colorWithAlphaComponent(0.5)


        buttonSelect.tintColor = white
        buttonSelect.setImage(UIImage(named: "image")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), forState: UIControlState.Normal)

//        buttonSelect.setImage(UIImage(named: "image")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), forState: UIControlState.Highlighted)
//        buttonSelect.setImage(UIImage(named: "image")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), forState: UIControlState.Selected)

        buttonSelect.imageView?.contentMode = UIViewContentMode.ScaleAspectFit

states Highlighted and Selected do not give visible influences
