收到通知并启用 Touch ID 时如何打开特定的 ViewController

【中文标题】收到通知并启用 Touch ID 时如何打开特定的 ViewController【英文标题】：How to open a particular ViewController when notification received and Touch ID is enabled 【发布时间】：2019-05-23 05:52:07 【问题描述】：我是 ios Swift 的新手。我在我的应用程序中添加了 LocalAuthentication(TouchID) 功能。启用触摸 ID 后，我在仪表板页面上重定向用户，成功验证。现在，当收到推送通知时，如果它是类别类型的博客，我想打开博客页面，如果它是类别类型的支付，我想打开支付页面，如果是新闻我想打开通知页面。但是由于启用了触摸 id，我正在重定向到仪表板页面，而不是在收到通知的特定 ViewController 上。不明白如何处理这种情况。
收到通知后我在做什么：
func navigateToView(userInfo: [AnyHashable: Any])
let userInfo = userInfo
if userInfo[AnyHashable("click_action")] != nil
category = (userInfo[AnyHashable("click_action")] as? String)!
let userauthenticate = UserDefaults.standard.bool(forKey: "userauth")
print("USERINFOCOUNT: \(userInfo.count) \n CATEGORY : \(category) \n USERAUTH: \(userauthenticate)")
if(userauthenticate == true && category.isEmpty)
let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewControlleripad : UIViewController = mainStoryboardIpad.instantiateViewController(withIdentifier: "Dashboard") as UIViewController
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewControlleripad
self.window?.makeKeyAndVisible()
else if(userauthenticate == true && category == "notification")
saveNewNotificationInBackground(userInfo: userInfo)
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "openNotifications"), object: nil)
defaults.set(userInfo, forKey: "userInfo")
defaults.synchronize()

【问题讨论】：
看看这个link希望对你有帮助 此链接不符合我的目的。 能不能贴一下通知功能代码对你有帮助 请检查上述编辑代码中的 navigateToView() 函数。在收到通知和身份验证时，我正在调用相同的函数。 通过了解您的应用程序根并进一步查看控制器的层次结构。 【参考方案1】：将成功博客中的代码替换为这个，
func goToBlogVC()
DispatchQueue.main.async
let storyboard = UIStoryboard(name: "Main", bundle: nil)
if let mainView = storyboard.instantiateViewController(withIdentifier: "blogVC") as? blogVC
self.window = UIWindow(frame: UIScreen.main.bounds)
let nav1 = UINavigationController()
nav1.isNavigationBarHidden = true //Show or hide nav bar
nav1.viewControllers = [mainView]
self.window!.switchRootViewController(nav1)
self.window?.makeKeyAndVisible()
你能告诉我你被击中的地方吗，你的代码看起来很完美，但流程太庞大了一旦你收到通知然后触发 authenticationWithTouchID 成功转到相关控制器[失败让输入他们的密码]，下面是我的代码
导航流程
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void)
if isblog
self.jumpToScreen()
completionHandler()
func jumpToScreen()
if let vc = self.window?.visibleViewController
if vc.isKind(of: blogVC.self)
return
else if vc.isKind(of: DashboardVC.self)
self.goToBlogVC()
else
print("Other Screens")
【讨论】：
使用上面的代码让我知道应用程序是否仍然崩溃 我们可以单独聊聊吗 当然是sagarchavan 我已经更新了我的整个 appdelegate.swift 文件。我只是不明白为什么如果启用触摸 ID 并收到通知，我无法打开特定控制器 让我们continue this discussion in chat。以上是关于收到通知并启用 Touch ID 时如何打开特定的 ViewController的主要内容，如果未能解决你的问题，请参考以下文章
