Keep UIButton Selected/Highlighted after touch

Question

I\'d like my button to remain highlighted after the user taps it. If the user taps the button again I\'d like it to become de-selected/unhighlighted. I\'m not sure how to go

Answer 1

this one worked fine for me!

func buttonColorChanger(sender :  UIButton )  {

    if button.isSelected == false
    {

        button.backgroundColor = UIColor.purple
        print("selected")

        button.setTitle("selected", for: .normal)
        button.setTitleColor(UIColor.white, for: .normal)
         button.isSelected = true
    }else{

        button.backgroundColor = UIColor.white
        print("unselected")
        button.isSelected = false

    }
}
