Question

我尝试从本地通知中打开特定的View控制器..我在 AppDelegate 中添加了操作和类别以及 scheduleNotification的功能。当我尝试打开任何ViewController（故事板）时，每件事似乎都好！除非打开ViewController（storyboard），它具有发送通知功能..

当我评论它时，这是ViewController中的函数，它工作！：

func expiredDate() {
    print("start")

    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy/MM/dd" //format the date to match how it's stored in Firebase
    let ref = FIRDatabase.database().reference(withPath: "/Data/\(user!.uid)/")




    ref.child("EssentialsList").observeSingleEvent(of: .value, with: { (snapshot) in
        for child in snapshot.children {
            let snap = child as! FIRDataSnapshot
            let dict = snap.value as! [String: Any]

            let eventDateStampString = dict["date"] as! String
            let endDate = formatter.date(from: eventDateStampString)

            let calendar = NSCalendar.current as NSCalendar

            var comps = DateComponents()
            comps.day = -5
            let exDate = calendar.date(byAdding: comps,
                                       to: endDate! , options: [])

            print(" expired date: \(String(describing: exDate))")

            let delegate = UIApplication.shared.delegate as? AppDelegate
            delegate?.scheduleNotification(at: exDate!)

                       }
    })

}

这里是AppDelegate中句柄Action的代码：

extension AppDelegate: UNUserNotificationCenterDelegate {
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    switch response.actionIdentifier {
    case "ViewEss":
        print("ViewEss")
        //       let myTabBar = self.window?.rootViewController as! UIViewController
        self.window?.rootViewController = self.storyboard?.instantiateViewController(withIdentifier: "HelloID")

    case "ViewCar":
        print("ViewCar")
        //       let myTabBar = self.window?.rootViewController as! UIViewController
        self.window!.rootViewController = self.storyboard!.instantiateViewController(withIdentifier: "CarAll")


    default:
        print("Other Action")
        self.window?.rootViewController = self.storyboard?.instantiateViewController(withIdentifier: "MainAndCar")


    }

}

}

打开通知后的错误锥：

ViewEss 致命错误：在展开Optional值时意外发现nil 2017-05-08 00：00：03.291397 ade-mc-trial [2164：659918]致命错误：在解包可选值时意外发现nil （lldb）

错误打开发送本地通知的相同视图
