SEPolymorphButton

SEPolymorphButton is a subclass of UIControl that simulate the basic behavior of button and allows to transform own shape to circle, heart or star. Written in Swift, requires iOS 8 or later.

#Usage

let polyButton = SEPolymorphButton()
view.addSubview(polyButton)
...
polyButton.changeStyle(.💛, animationDuration: 0.5)
// alternative: polyButton.changeStyle(.heartStyle, animationDuration: 0.5)
polyButton.changeStyle(.🌕, animationDuration: 0.5)
// alternative: polyButton.changeStyle(.circleStyle, animationDuration: 0.5)
