应用终止时未调用UNUserNotificationCenter didReceive响应

Question

我正在处理本地通知，但我遇到的问题是，当应用程序终止时，方法didReceive响应不会被调用，所以当我点击通知操作时，它只会启动应用程序，而不做任何其他事情。但是，当应用程序只在后台运行时，一切都照常运行。我的代码有什么问题吗？

//MyClassNameViewController.swift

override func viewDidLoad() {
    super.viewDidLoad()

    UNUserNotificationCenter.current().delegate = self

}

func triggerAlarm1() {
    // Create an instance of notification center
    let center = UNUserNotificationCenter.current()

    // Sets the details of the notification
    let content = UNMutableNotificationContent()
    content.title = "Recorded Today's first alarm."
    content.body = "Be completely honest: how is your day so far?"
    content.sound = UNNotificationSound.default()
    content.categoryIdentifier = "notificationID1"

    // Set the notification to trigger everyday
    let triggerDaily = Calendar.current.dateComponents([.hour,.minute], from: myTimePicker1.date)
    let trigger = UNCalendarNotificationTrigger(dateMatching: triggerDaily, repeats: true)

    // Deliver the notification
    let identifier = "UYLLocalNotification"
    let request = UNNotificationRequest(identifier: identifier,
                                        content: content, trigger: trigger)
    center.add(request, withCompletionHandler: { (error) in
        if error != nil {
            // Just in case something went wrong
            print(error!)
        }
    })

}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    print("didReceive Method called")

    if response.actionIdentifier == "actionOne" {
        let alertOne = UIAlertController(title: "First", message: "Some Message Here", preferredStyle: UIAlertControllerStyle.alert)
        let actionOne = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil)
        alertOne.addAction(actionOne)
        self.present(alertOne, animated: true, completion: nil)
    }
    completionHandler()
}

//AppDelegate.swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    UNUserNotificationCenter.current().delegate = self

    // Request Authorisation
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert , .sound , .badge]) { (Bool, error) in
        // insert code here
    }

    let actionOne = UNNotificationAction(identifier: "actionOne", title: "Open1", options: [.foreground])
    let catogeryOne = UNNotificationCategory(identifier: "notificationID1", actions: [actionOne], intentIdentifiers: [], options: [])
    UNUserNotificationCenter.current().setNotificationCategories([catogeryOne])

    return true
}

在你的动作标识符内调用这个函数，你就会好起来！

 func alertAction() {

    let alertController = UIAlertController(title: "Hello", message: "This is cool!", preferredStyle: .alert)
    alertController.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action) in
        // Do something with handler block
    }))

    let pushedViewControllers = (self.window?.rootViewController as! UINavigationController).viewControllers
    let presentedViewController = pushedViewControllers[pushedViewControllers.count - 1]

    presentedViewController.present(alertController, animated: true, completion: nil)
}

这非常简单！

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    print("didReceive Method called")

    if response.actionIdentifier == "actionOne" {
        DispatchQueue.main.async(execute: {
            self.alertAction()
        })
    } else if response.actionIdentifier == "actionTwo" {

    } else if response.actionIdentifier == "actionThree" {

    }
    completionHandler()
}

完全适用于Swift 3.0和Xcode 8.0。我已经更改了视图控制器之间的所有连接。我已经在初始ViewController中添加了一个NavigationController。

AppDelegate：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.


    let center = UNUserNotificationCenter.current()
    center.delegate = self

    // Request Authorisation
    center.requestAuthorization(options: [.alert , .sound , .badge]) { (Bool, error) in
        // insert code here
    }

    let actionOne = UNNotificationAction(identifier: "actionOne", title: "Open1", options: [.foreground])
    let catogeryOne = UNNotificationCategory(identifier: "notificationID1", actions: [actionOne], intentIdentifiers: [], options: [])

    let actionTwo = UNNotificationAction(identifier: "actionTwo", title: "Open2", options: [.foreground])
    let catogeryTwo = UNNotificationCategory(identifier: "notificationID2", actions: [actionTwo], intentIdentifiers: [], options: [])

    let actionThree = UNNotificationAction(identifier: "actionThree", title: "Open3", options: [.foreground])
    let catogeryThree = UNNotificationCategory(identifier: "notificationID3", actions: [actionThree], intentIdentifiers: [], options: [])

    UNUserNotificationCenter.current().setNotificationCategories([catogeryOne, catogeryTwo, catogeryThree])

    return true
}


func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    print("willPresent method called")
    completionHandler([.alert, .sound])
}

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

    print("didReceive Method called")

    if response.actionIdentifier == "actionOne" {
        DispatchQueue.main.async(execute: {
            self.alertAction()
        })
    } else if response.actionIdentifier == "actionTwo" {

    } else if response.actionIdentifier == "actionThree" {

    }
    completionHandler()
}



func alertAction() {

    let alertController = UIAlertController(title: "Hello", message: "This is cool!", preferredStyle: .alert)
    alertController.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action) in
        // Do something with handler block
    }))

    let pushedViewControllers = (self.window?.rootViewController as! UINavigationController).viewControllers
    let presentedViewController = pushedViewControllers[pushedViewControllers.count - 1]

    presentedViewController.present(alertController, animated: true, completion: nil)
}

此外，我已经从viewDidLoad和其他地方删除了所有以前的建议。

更改与show的连接，并且不要以模式显示。如果你想在任何地方显示你的提醒。祝好运
