Override UIButton's setEnabled method in Swift

Question

In Swift, UIControl doesn't seem to have a setEnabled: method. Is there a way to detect when the control state was changed?

Answer 1

You can do something like that in your subclass:

override var enabled:Bool {
    didSet {
        //Your code
    }
}

Swift 3.0

override var isEnabled:Bool {
    didSet {
        //Your code
    }
}

Thanks! Completely forgot that we can override properties in Swift – Clementia

I was wondering if we could ovveride properties in swift the moment I fell on this!!! – Timmons

Just a note that you do not need to call super here - Swift does that automatically when overriding properties. – Maddiemadding

Answer 2

In swift 3 it is now:

override var isEnabled: Bool {
    didSet {
        //Your code
    }
}
