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

To make the button is faded when disable, you can set alpha for it. There are two options for you:

First way: If you want to apply for all your buttons in your app, so you can write extension for UIButton like this:

extension UIButton {

    open override var isEnabled: Bool{
        didSet {
            alpha = isEnabled ? 1.0 : 0.5
        }
    }

}

Second way: If you just want to apply for some buttons in your app, so you can write a custom class from UIButton like below and use this class for which you want to apply:

class MyButton: UIButton {
    override var isEnabled: Bool {
        didSet {
            alpha = isEnabled ? 1.0 : 0.5
        }
    }
}
