Buttons & Enums

Question

I'm little bit confuse with this.. I can't find anything from output "Preview".. O_o CMIIW please..

buttons.swift

import Foundation

enum UIBarButtonStyle {
    case Done
    case Plain
    case Bordered
}

class UIBarButtonItem {

    var title: String?
    let style: UIBarButtonStyle
    var target: AnyObject?
    var action: Selector

    init(title: String?, style: UIBarButtonStyle, target: AnyObject?, action: Selector) {
        self.title = title
        self.style = style
        self.target = target
        self.action = action
    }
}

enums.swift

enum Button {
    case Done(String)
    case Edit(String)

    func toUIBarButtonItem() -> UIBarButtonItem {
        switch self {
          case .Done(let titles):
            return UIBarButtonItem(title: titles, style: UIBarButtonStyle.Done, target: nil, action: nil)
          case .Edit(let titles):
            return UIBarButtonItem(title: titles, style: UIBarButtonStyle.Plain, target: nil, action: nil)
        }
    }
}

let doneButton = Button.Done("Done")

Try something like this:

enum Button { case Done(String) case Edit(String) case Bordered(String)

func toUIBarButtonItem() -> UIBarButtonItem {
    switch self {
    case .Done(let doneValue):
        return UIBarButtonItem(title: doneValue, style: UIBarButtonStyle.Done, target: nil, action: nil)
    case .Edit(let editValue):
        return UIBarButtonItem(title: editValue, style: UIBarButtonStyle.Plain, target: nil, action: nil)
    case .Bordered(let borderValue):  //not in challenge
        return UIBarButtonItem(title: borderValue, style: UIBarButtonStyle.Plain, target: nil, action: nil)
    }
}

}

let done = Button.Done("Done") let doneButton = done.toUIBarButtonItem()

let borderedButton = bordered.toUIBarButtonItem()
