enum BarButton {
case done(title: String)
case edit(title: String)
func button() -> UIBarButtonItem{
switch self {
case .done(let title):
return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
case .edit(let title):
return UIBarButtonItem(title: title, style: .plain, target: nil, action: nil)
}
}
}
let done = BarButton.done(title: "Save")
let doneButton = done.button()
