如何替换折旧的 UILocalNotification 并在 iOS 10 中添加 UNNotificationAction

Question

我在 ViewController.swift 中创建了一个计划通知，需要向该通知添加两个操作。一个说 "Call"，另一个说 "Cancel"。如何在 ViewController.swift 中添加这些操作？这是代码的一部分，它具有在 ViewController.swift:

中触发我的通知的功能

func notificationFires(){

    let notification = UILocalNotification()
    // 2
    notification.soundName = UILocalNotificationDefaultSoundName
    notification.fireDate = datePicker.date

    // 3
    if textField.text == "" {

        notification.alertBody = "You have a call right now!"

    }
    else{

        notification.alertBody = self.textField.text

    }
    // 4
    notification.timeZone = NSTimeZone.default
    // 5
    // 6
    notification.applicationIconBadgeNumber = 1
    // 7
    UIApplication.shared.scheduleLocalNotification(notification)



    func application(application: UIApplication,  didReceiveRemoteNotification userInfo: [NSObject : AnyObject],  fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {
        print("Recived: notification")



        if cancelled == true{
            print("cancelled happened")

        }
        func cancelNotify(){
            cancelled = true
            UIApplication.shared.cancelAllLocalNotifications()
        }
        completionHandler(.newData)

    }

}

我在 iOS 10 中还没有使用过通知，所以我继续把它想出来作为自己的学习经验，现在我可以将它传递给你。

UILocalNotification 在 iOS 10 中贬值并被 UserNotifications 框架取代。

在您的 AppDelegate 中获得用户的授权以显示通知并设置中心委托 UNUserNotificationCenterDelegate:

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

    let center = UNUserNotificationCenter.current()
    center.delegate = self
    let options: UNAuthorizationOptions = [.alert, .sound];
    center.requestAuthorization(options: options) {
        (granted, error) in
        if !granted {
            print("Something went wrong")
        }
    }

    return true
}

向用户显示通知：

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    // Play sound and show alert to the user
    completionHandler([.alert,.sound])
}

处理动作：

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

    // Determine the user action
    switch response.actionIdentifier {
    case UNNotificationDismissActionIdentifier:
        print("Dismiss Action")
    case UNNotificationDefaultActionIdentifier:
        print("Default")
    case "foo":
        print("foo")
    case "bar":
        print("bar")
    default:
        print("Unknown action")
    }
    completionHandler()
}

在您想要为应用中的所有通知设置所有操作和类别的任何位置执行此操作。因为它们被分配到中心，而不是通知本身：

func setupActions() {

    //create first action
    let foo = UNNotificationAction(
        identifier: "foo",
        title: "foo"
    )

    //create second action
    let bar = UNNotificationAction(
        identifier: "bar",
        title: "bar",
        options: [.destructive]
    )

    //put the two actions into a category and give it an identifier
    let cat = UNNotificationCategory(
        identifier: "cat",
        actions: [foo, bar],
        intentIdentifiers: []
    )

    //add the category to the notification center
    UNUserNotificationCenter.current().setNotificationCategories([cat])
}

最后创建实际通知：

func setupNotification() {

    let content = UNMutableNotificationContent()

    content.title = "Hello!"
    content.body = "A message"
    content.sound = UNNotificationSound.default()

    //make sure to assign the correct category identifier
    content.categoryIdentifier = "cat"

    // Deliver the notification in five seconds.
    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
    let request = UNNotificationRequest(identifier: "hello", content: content, trigger: trigger)
    let center = UNUserNotificationCenter.current()

    center.add(request) { (error : Error?) in
        if let theError = error {
            print("theError \(theError)")
        }
    }
}

确保在每个 class 中 import UserNotifications 使用这些功能。
