在父视图Swift中选择方法

Question

假设我有UIView的自定义UIButton。此按钮的目标可以引用自定义UIView的父视图中的选择器吗？甚至从实现视图传递选择器？我试过以下没有运气：

class CustomView: UIView {
    var button = UIButton()

    override init(frame: CGRect) {
        super.init(frame: frame)

        let buttonSize = min(frame.height, frame.width)/2.0
        self.button = UIButton(frame: CGRectMake(0.0, 0.0, buttonSize, buttonSize))
        self.button.setTitle("Example Title", forState: .Normal)
        self.button.center = self.center
        self.addSubview(button)

    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }

    func addTargetToButton(selector: Selector) {
        self.button.addTarget(self, action: selector, forControlEvents: .TouchUpInside)
    }

}

我希望使用类似这样的东西来创建一个菜单，其中包含未定义数量的按钮，这些按钮都可以在实现UIViewController中被赋予目标。这将是VC的基本语法：

private extension Selector {
    static let actionIWantTapped = #selector(CustomViewController.actionIWant(_:))
}

class CustomViewController: UIViewController {
    var customView = UIView()

    override func viewDidLoad() {
        super.viewDidLoad()
        customView = UIView(frame: self.view.frame)
        customView.addTargetToButton(.actionIWantTapped)

    }

    func actionIWant(sender: UIButton!) {
        // do something
    }

}
