ios - 关闭 View Controller 不会返回到前一个 View Controller
<p><p>根据我的应用程序的需要，在推送另一个带有动画的 ViewController 后，我正在展示一个 ViewController 。代码如下:</p>
<pre><code> 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)
}
</code></pre>
<p>在呈现的 ViewController 中，我分配了一个侧边菜单 Controller ，因为我需要在向右滑动时显示侧边菜单:</p>
<pre><code>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()
}
</code></pre>
<p>现在我在这个 ViewController 中有一个自定义的后退按钮。单击它时，我需要关闭 ViewController 并显示 ViewController 的显示位置。名称为“HomeSearchViewController”</p>
<p>为了解除我在按钮操作中写了以下代码:</p>
<pre><code> func navigateToPreviousController() {
self.dismiss(animated: true, completion: nil)
}
</code></pre>
<p>但这并没有解除 ViewController 。我可以知道是什么问题吗？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>为了关闭 ViewController ，您的 ViewController 应嵌入导航 Controller 中。</p>
<p>例如:</p>
<pre><code>let controller =storyboard.instantiateViewController(withIdentifier: "storyboardidentifier") as! yourviewcontroller
let navController = UINavigationController(rootViewController: controller)
present(navController, animated: true, completion: nil)
</code></pre>
<p>然后在呈现的 ViewController 上，如果您使用以下代码，它将关闭 ViewController 。</p>
<pre><code>func dismissButtonPressed(){
self.dismiss(animated: true, completion: nil)
}
</code></pre>
<p>干杯!!</p></p>
