        /* active stage is working */ 
    } else if (application.applicationState == UIApplicationState.inactive || application.applicationState == UIApplicationState.background) {
        if (type == "1" || type == "2") {
            let storyboard: UIStoryboard = UIStoryboard(name: "MyAppointments", bundle: nil)
            let apptVC = storyboard.instantiateViewController(withIdentifier: "NotificationDetailViewController") as! NotificationDetailViewController
            let navigationController = UINavigationController.init(rootViewController: apptVC)
            self.window?.rootViewController = navigationController
            self.window?.makeKeyAndVisible()
        } else if (type == "3") {
            let storyboard: UIStoryboard = UIStoryboard(name: "MyAppointments", bundle: nil)
            let apptVC = storyboard.instantiateViewController(withIdentifier: "NotificationDetailViewController") as! NotificationDetailViewController
            let navigationController = UINavigationController.init(rootViewController: apptVC)
            self.window?.rootViewController = navigationController
            self.window?.makeKeyAndVisible()
        } else if (type == "4") {
            let storyboard: UIStoryboard = UIStoryboard(name: "Enquiry", bundle: nil)
            let enqVC = storyboard.instantiateViewController(withIdentifier: "EnquiryDetailViewController") as! EnquiryDetailViewController
            let navigationController = UINavigationController.init(rootViewController: enqVC)

}

I can get notification and tap to move specific VC when application is active. Please help me what I am missing.

推荐答案

当您的应用程序处于关闭状态时，您应该检查启动选项

When you app is in closed state you should check for launch option in

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { }

并调用您的 API.

示例:

if let option = launchOptions {
  let info = option[UIApplicationLaunchOptionsKey.remoteNotification]
  if (info != nil) {
    goAnotherVC()
  }
}
