Disabled UIButton not faded or grey

Question

In my iPhone app, I have a UIButton which I have created in Interface Builder. I can successfully enable and disable it like this in my code ...

sendButton.e         


        

Answer 1

Create an extension in Swift > 3.0 rather than each button by itself

extension UIButton {
    override open var isEnabled : Bool {
        willSet{
            if newValue == false {
                self.setTitleColor(UIColor.gray, for: UIControlState.disabled)
            }
        }
    }
}
