Quick Start

  1. Add a PopBounceButton to your view.

    let frame = CGRect(origin: .zero, size: CGSize(width: 100, height: 100))
let button = PopBounceButton(frame: frame)
view.addSubview(button)

  2. Attach a target to your button to handle any events.

    button.addTarget(self, action: #selector(handleTap), for: .touchUpInside)
    @objc func handleTap(_ sender: PopBounceButton) {
    //do something
}

Customization

Because PopBounceButton is a subclass of UIButton, it can be customized in the same way. The button's animations can be changed by modifying the following variables exposed by PopBounceButton:

var springBounciness: CGFloat = 19.0
var springSpeed: CGFloat = 10.0
var springVelocity: CGFloat = 6.0

var cancelTapScaleDuration: TimeInterval = 0.3

var longPressScaleFactor: CGFloat = 0.7
var longPressScaleDuration: TimeInterval = 0.1
var minimumPressDuration: TimeInterval = 0.2
