Use custom appearance

You can also implement your self the custom appearance by implementing CustomStyleConfigurable protocol. This protocol allow you to handle custom appearance yourself. Basicly you should tell the sdk how to apply the appearances by implementing functions lg_apply & lg_unapply.

let blueBlock = "blue".build(UIImageView).style([.custom(["shadowColor": UIColor.brownColor(), "shadowOpacity": 1.0])])

extension UIView: CustomStyleConfigurable {
    public func lg_unapply(customStyle style: [String : Any]) {
        if let view = self as? UIImageView,
        let _ = style["shadowColor"] as? UIColor,
        let _ = style["shadowOpacity"] as? Float {
            view.layer.shadowColor = UIColor.black.cgColor
            view.layer.shadowOpacity = 0.0
        }
    }

    public func lg_apply(customStyle style: [String : Any]) {
        if let view = self as? UIImageView,
        let color = style["shadowColor"] as? UIColor,
        let opacity = style["shadowOpacity"] as? Float {
            view.layer.shadowColor = color.cgColor
            view.layer.shadowOpacity = opacity
        }
    }
}

Warning: should be careful to implement these two methods as a pair, if you tell the framework how to apply a custom style, you need also to tell how to unapply this custom style. Otherwise you may have some unexpected effects.
