ios - 我想在 UIView 类中按下按钮时触发导航 Controller

Question

当我按下 UIView 类中的按钮时，我想将导航 Controller 触发到其他屏幕。我怎样才能做到这一点？

//创建按钮Iboutlet的UIView类代码

import UIKit

protocol ButtonDelegate: class  {
    func buttonTapped()
}

class SlidesVC: UIView {

  var delegate: ButtonDelegate?

   @IBAction func onClickFinish(_ sender: UIButton) {

   delegate?.buttonTapped()

   }

   @IBOutlet weak var imgProfile: UIImageView!

    }

   //ViewController Class code in Which Button Protocol will be entertained

  class SwipingMenuVC: BaseVC, UIScrollViewDelegate {
         var  slidesVC = SlidesVC()

             override func viewDidLoad() {
                    super.viewDidLoad()

                    slidesVC = SlidesVC()
                    // add as subview, setup constraints etc
                    slidesVC.delegate = self

        }

extension BaseVC: ButtonDelegate {
  func buttonTapped() {

 self.navigationController?.pushViewController(SettingsVC.settingsVC(), 
            animated: true)

   }
   }

更简单的方法是使用类型别名。您必须在 2 个地方编写代码。 1. 您的 viewClass 和 2. 在您的 View Controller 中。

在您的 SlidesView 类中添加一个类型别名并定义参数类型(如果您需要)，否则将其留空。

class SlidesView: UIView {
typealias OnTapInviteContact = () -> Void
var onTapinviteContact: OnTapInviteContact?

    @IBAction func buttonWasTapped(_ sender: UIButton) {
    if self.onTapinviteContact != nil {
      self.onTapinviteContact()
    }

  }
}

  class SwipingMenuVC: BaseVC, UIScrollViewDelegate {
             override func viewDidLoad() {
                    super.viewDidLoad()

                    let slidesView = SlidesView()
                    slidesView.onTapinviteContact = { () in
                    // do whatever you want to do on button tap
            }

        }
