【问题描述】:
我有一个嵌入在导航堆栈中的带有 5 个屏幕的小应用程序,我无法关闭 UIViewController
我在我的项目中使用SideMenu 来展示最后一个UIViewController,这是侧边菜单的代码配置:
SideMenuManager.default.menuPushStyle = .replace
SideMenuManager.default.menuPresentMode = .menuSlideIn
以及我介绍 VC 的方式:
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "menuToSavedQuotes" {
_ = segue.destination as? SavedQuotesViewController
}
}
然后:self.performSegue(withIdentifier: "menuToSavedQuotes", sender: self)
它工作得很好,但是当我要求解雇时 - 这不起作用。我没有在我的应用程序中使用导航栏,这就是我创建按钮并试图将其关闭但失败的原因。
我尝试的是:
self.navigationController?.popViewController(animated: true)
self.dismiss(animated: true, completion: nil)
但是这些都不起作用。我现在拥有但仍然无法工作的是:
override func viewDidLoad() {
super.viewDidLoad()
output?.viewIsReady()
setupNavigationStack()
}
@IBAction func didPressClose(_ sender: UIButton) {
print("Here")
self.navigationController?.popViewController(animated: true)
//self.dismiss(animated: true, completion: nil)
}
func setupNavigationStack() {
if let root = UIApplication.shared.keyWindow?.rootViewController as? StartingPageViewController {
let navigation = root.childViewControllers[0] as! UINavigationController
let vc1 = self.storyboard!.instantiateViewController(withIdentifier: "StartingPage")
let vc2 = self.storyboard!.instantiateViewController(withIdentifier: "StartTrial")
let vc3 = self.storyboard!.instantiateViewController(withIdentifier: "ScheduleNotifications")
let vc4 = self.storyboard!.instantiateViewController(withIdentifier: "AllQuotes")
let vc5 = self.storyboard!.instantiateViewController(withIdentifier: "SavedQuotes")
navigation.setViewControllers([vc1, vc2, vc3, vc4, vc5], animated: true)
}
}
作为一个临时解决方案,我的关闭按钮只是打开以前的UIViewController,但这不是一个好习惯。
不胜感激!
谢谢!
