ios - 应用程序终止时未调用 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没有调用方法 didReceive Response 所以当我点击通知操作时它只是启动应用程序而没有做任何其他事情。但是当应用程序只是在后台时，一切都会照常运行。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
}

在你的动作标识符中调用这个函数，你会没事的！

 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)
}

超级简单！

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NavigationController在最初的ViewController.

应用委托：

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，我已经删除了来自viewDidLoad和其他地方的所有以前的建议。

将您的连接更改为show不以模态方式显示。如果您想在任何地方显示警报。祝你好运
