Swift - UIButton overriding setSelected

Question

I\'m making a UIButton subclass in Swift to perform custom drawing and animation on selection

What would be the equivalent in Swift of overriding - (void)setSe

Answer 1

you'd do it like e.g. this:

class MyButton : UIButton {

    // ...

    override var isSelected: Bool {
        willSet(newValue) {
            super.isSelected = newValue;
            // do your own business here...
        }
    }

    // ...

}
