永久着色UIImageView

Question

I'd like to tint a UIImageView, but as of now when I tint it and use the control (for example a button press), the tint disappears. Any thoughts?

class func tintImageView(imageView : UIImageView, withColor color:UIColor) {

    var coloredImage = imageView.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
    imageView.image = coloredImage
    imageView.tintColor = color
}

按钮的controlState可能已更改，并且每个controlState都有自己的imageView。
