NerdzStyle

NerdzStyle library allow to easily create and apply CSS-like styles to view elements.

Example

You will need to create a style to be able to use it later on. There are two options how you can do that.

Style creation from aim class

let borderedViewStyle = UIView.style {
    $0.layer.borderWidth = 1
    $0.layer.borderColor = UIColor.white.cgColor
    $0.layer.cornerRadius = 16
}

Manual style creation

let borderedViewStyle = Style<UIButton> {
    $0.layer.borderWidth = 1
    $0.layer.borderColor = UIColor.white.cgColor
    $0.layer.cornerRadius = 16
}

Also you can inherit from another style to create a custom hierarchy

Style inheriting from aim class

let plainButtonStyle = UIButton.style(parent: borderedViewStyle) {
    $0.setTitleColor(.green, for: .normal)
    $0.layer.borderColor = UIColor.green.cgColor
    $0.titleLabel?.font = UIFont.preferredFont(forTextStyle: .largeTitle)
}

Manual style inheritence

let plainButtonStyle = Style<UIButton>(parent: borderedViewStyle) {
    $0.setTitleColor(.green, for: .normal)
    $0.layer.borderColor = UIColor.green.cgColor
    $0.titleLabel?.font = UIFont.preferredFont(forTextStyle: .largeTitle)
}

To apply Style into some view instance you can use one of two possible ways

Applying from view

myButton.apply(plainButtonStyle)

Applying from style

plainButtonStyle.apply(to: myButton)

Also you can apply more than one style at once. The style priority will be increasing from left to right

Applying several styles to view

myButton.apply(buttonStyle1, buttonStyle2, buttonStyle3)

You can also apply same style to several views

Applying style to several views

plainButtonStyle.apply(to: button1, button2, button3)

Because of a generics you will be forced to use the same generic parameters as view type you are applyying style to. If you want to apply style with another generic parameter - you can user wrapped function from Style class

Using wrap function

myButton.apply(borderedViewStyle.wrapped())
