Introduction
The purpose of the BlowMindStyle library is to provide the infrastructure for application styling. BlowMindStyle allows:
- write reusable styles for views
- write reusable styles for text formatting (based on SemanticString)
- add application themes
- dynamically update views depending on trait collection and theme
- dynamically update views depending on a model state.
Basic usage
- Add resources, that will be used for stylization:
struct ButtonProperties {
var backgroundColor: UIColor?
var cornerRadius: CGFloat?
var titleColor: UIColor?
var font: UIFont?
var contentEdgeInsets: UIEdgeInsets?
}- Define style:
final class ButtonStyle<Environment: StyleEnvironmentType>: EnvironmentStyle<ButtonProperties, Environment> { }- Apply resources to view:
extension EnvironmentContext where Element: UIButton {
var buttonStyle: StylableElement<ButtonStyle<StyleEnvironment>> {
stylableElement { button, style, resources in
button.setTitleColor(resources.titleColor, for: .normal)
let cornerRadius = resources.cornerRadius ?? 0
if let normalColor = resources.backgroundColor {
let normalBackground = UIImage.resizableImage(withSolidColor: normalColor, cornerRadius: cornerRadius)
button.setBackgroundImage(normalBackground, for: .normal)
} else {
button.setBackgroundImage(nil, for: .normal)
}
button.titleLabel?.font = resources.font ?? UIFont.systemFont(ofSize: UIFont.buttonFontSize)
button.contentEdgeInsets = resources.contentEdgeInsets ?? .zero
}
}
}- Use style:
button.setUpStyles {
$0.buttonStyle.apply(.primary)
