SimpleButton

UIButton subclass with animated, state-aware attributes. Easy to subclass and configure! Full API docs


Usage

Just create your own SimpleButton subclass and configure your button attributes by overriding configureButtonStyles.

class PrimaryButton: SimpleButton {
    override func configureButtonStyles() {
        super.configureButtonStyles()
		setBorderWidth(4.0, for: .normal)
        setBackgroundColor(UIColor(red: 52/255, green: 73/255, blue: 94/255, alpha: 1.0), for: .normal)
        setBackgroundColor(UIColor(red: 44/255, green: 62/255, blue: 80/255, alpha: 1.0), for: .highlighted)
        setBorderColor(UIColor(red: 44/255, green: 62/255, blue: 80/255, alpha: 1.0), for: .normal)
        setScale(0.98, for: .highlighted)
        setTitleColor(UIColor.whiteColor(), for: .normal)
    }
}

For usage in Interfacebuilder, just use your SimpleButton subclass as custom class for any UIButton element. All defined styles gets applied automatically.

You can also configure your button without a subclass directly inline.

let awesomeButton = SimpleButton(type: .custom)
awesomeButton.setBorderWidth(2.0, for: .normal)
awesomeButton.setBorderColor(UIColor.redColor(), for: .highlighted)
view.addSubview(awesomeButton)

Note that you should use UIButtonType.custom to avoid undesired effects.

Please checkout the example project for a detailed usage demo.

Animation

Each state change of SimpleButton animates by default. Sometimes you need to define which state transition should animate and which should happen immediately. Therefore you can control that behaviour with the animated and animationDuration parameters.

setBorderWidth(4.0, for: .normal, animated: true, animationDuration: 0.2)
setBorderWidth(8.0, for: .highlighted, animated: false)

This means, every state change to .normal animates the borderWidth to 4.0. Every state change to .highlighted changes instantly the borderWidth to 8.0 without animation.

Loading state

SimpleButton has a custom loading state. You can toggle this state by setting simpleButton.isLoading. The button shows an UIActivityIndicator instead of the title when adding the loading state.

simpleButton.setCornerRadius(20, for: SimpleButtonControlState.loading)
simpleButton.isLoading = true

If you don´t like the default loading indicator, you can set your own UIView by doing

simpleButton.loadingView = CustomAwesomeLoadingView()

Configurable attributes

Take a look at the Setter for state attributes section of the API Docs
