ios - 取消 View Controller 不会返回到先前的 View Controller

在我的应用程序需要使用动画推送另一个视图控制器之后，我将展示一个视图控制器。代码如下所示:

    func pushViewController() {
    let viewcontroller = UIStoryboard(name: "Home", bundle: nil).instantiateViewController(withIdentifier: "homeSearchIndentifier") as? HomeSearchViewController
    let searchViewController = UIStoryboard(name: "Home", bundle: nil).instantiateViewController(withIdentifier: "searchRideIdentifier") as? SearchRideViewController
    searchViewController?.parentView = .homeLandingPage
    let duration = 0.4
    let transition: CATransition = CATransition()
    transition.duration = duration
    transition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
    transition.type = kCATransitionPush
    transition.subtype = kCATransitionFromBottom
    self.navigationController!.view.layer.add(transition, forKey: kCATransition)
    self.navigationController?.pushViewController(viewcontroller!, animated: false)
    viewcontroller?.present(searchViewController!, animated: true, completion: nil)
  }

在显示的视图控制器中，我要分配一个侧边菜单控制器，因为我需要在向右滑动时显示侧边菜单:

override func viewDidLoad() {
    super.viewDidLoad()
    self.addSearchListScreen()
    self.locationManager.delegate = self
    yourLocation.layer.sublayerTransform = CATransform3DMakeTranslation(7, 0, 0)
    let leftViewController = UIStoryboard(name: "SideBar", bundle: nil).instantiateViewController(withIdentifier: "sideBar") as? SideBarViewController
    let slideMenuController = SlideMenuTrackerController(mainViewController: self, leftMenuViewController: leftViewController!)
    AppDelegate.sharedInstance().window?.rootViewController = slideMenuController
    leftViewController?.mainViewController = self
    slideMenuController.automaticallyAdjustsScrollViewInsets = true
    AppDelegate.sharedInstance().window?.backgroundColor = UIColor(red: 236.0, green: 238.0, blue: 241.0, alpha: 1.0)
    AppDelegate.sharedInstance().window?.makeKeyAndVisible()
  }

现在，我在此视图控制器中有一个自定义的后退按钮。单击它时，我需要关闭视图控制器，并从显示它的位置显示视图控制器。名称为“HomeSearchViewController”

为了解雇我在按钮操作中编写了以下代码:

    func navigateToPreviousController() {
      self.dismiss(animated: true, completion: nil)
  }

但这并不能消除视图控制器。我可以知道是什么问题吗？

最佳答案

为了关闭视图控制器，您的视图控制器应嵌入导航控制器中。

例如:

let controller =storyboard.instantiateViewController(withIdentifier: "storyboardidentifier") as! yourviewcontroller
    let navController = UINavigationController(rootViewController: controller)
    present(navController, animated: true, completion: nil)

然后在显示的视图控制器上，如果您使用以下代码，它将关闭视图控制器。

func dismissButtonPressed(){
   self.dismiss(animated: true, completion: nil)
}

干杯!!
