swift - Swift 中带参数的静态函数的选择器？

Question

是否可以在 Swift 中使用带参数的静态函数的选择器？

我试过的语法是这样的:

  button.addTarget(VCPresenter.self, action: #selector(VCPresenter.handleBackButton(_:parentNavigationController!)), for: .touchUpInside)

静态方法就是这个

  @objc public static func handleBackButton(_ controller: UINavigationController) {
    controller.popViewController(animated: true);
}

当我编译时，我得到

Error:(24, 56) argument of '#selector' does not refer to an '@objc' method, property, or initializer

这甚至可以做到吗？

我用单 View 应用程序和这项工作创建了新项目。如果这对你有用，请告诉我。

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        let button = UIButton()
        button.addTarget(self, action: #selector(ViewController.buttonAction(x:y:)), for: .touchUpInside)
    }

    @objc public static func buttonAction(x: Int, y: String){
        print("Test")
    }
}
