關閉動作按鈕項上的動作按鈕，單擊Swift 4.2

Question

我正在按照本教程創建操作按鈕。 這是整個項目代碼。

var actionButton : ActionButton!
override func viewDidLoad() {
    super.viewDidLoad()
    setupButtons()
}

func setupButtons(){
    let google = ActionButtonItem(title: "Google", image: #imageLiteral(resourceName: "a1"))
    google.action = { item in self.view.backgroundColor = UIColor.red }
    let twitter = ActionButtonItem(title: "Twitter", image: #imageLiteral(resourceName: "a2"))
    twitter.action = { item in self.view.backgroundColor = UIColor.blue }
    let facebook = ActionButtonItem(title: "Facebook", image: #imageLiteral(resourceName: "a3"))
    let linkedin = ActionButtonItem(title: "Linkedin", image: #imageLiteral(resourceName: "a4"))
    actionButton = ActionButton(attachedToView: self.view, items: [google, twitter, facebook, linkedin])
    actionButton.setTitle("+", forState: UIControl.State())
    actionButton.backgroundColor = UIColor(red: 238.0/255.0, green: 130.0/255.0, blue: 130.0/255.0, alpha: 1)
    actionButton.action = { button in button.toggleMenu()}
}

該代碼可以正常工作，但是當我單擊操作按鈕項時，例如說Google或Twitter，我希望關閉操作按鈕。

只需為每個button.action添加self.actionButton.toggleMenu() button.action 。

例：

google.action = {
        item in self.view.backgroundColor = UIColor.red
        self.actionButton.toggleMenu()
    }
