用户通知请求始终带有默认操作标识符 [英] User Notification request always come with default action identifier

问题描述

我正在使用UNUserNotificationCenterDelegate（> ios 10）和其中一个委托方法，我可以检查来自通知的响应总是actionIdentifier等于com.apple.UNNotificationDefaultActionIdentifier，无论我做什么。 response.notification.request.content.categoryIdentifier是正确的，具有预期值，但request.actionIdentifier永远不会正确（下面的示例中为mycustomactionidentifier）。有没有人知道我是否遗漏了什么？

I am using the UNUserNotificationCenterDelegate (> ios 10) and one of the delegate methods where I can check the response from the notification has always actionIdentifier equal "com.apple.UNNotificationDefaultActionIdentifier" no matter what I do. The "response.notification.request.content.categoryIdentifier" comes right, with the expected value, but the request.actionIdentifier never comes correctly ("mycustomactionidentifier" in the example below). Does anyone know if I'm missing something?

extension NotificationManager: UNUserNotificationCenterDelegate {


    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Swift.Void) {

        completionHandler([.alert,.sound])
    }

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

        if response.notification.request.content.categoryIdentifier == "TEST" {
            if response.actionIdentifier == "mycustomactionidentifier" {
                NSLog("it finally works dude!")
            }
        }

        completionHandler()
    }
}

我添加了动作和通知中心的类别：

I added the action and category to the Notification center:

    let uploadAction = UNNotificationAction(identifier: "mycustomactionidentifier", title: "Uploaded", options: [])
    let category = UNNotificationCategory(identifier: "TEST", actions: [uploadAction], intentIdentifiers: [])
    center.setNotificationCategories([category])

并发送请求并输入正确的标识符：

and am sending the request putting the correct identifier:

    let uploadContent = UNMutableNotificationContent()
    uploadContent.title = String(number) + " asset(s) added"
    uploadContent.body = "Check your inventory to manage your assets!"
    uploadContent.categoryIdentifier = "TEST" 

    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 6, repeats: false)

    let uploadRequestIdentifier = "mycustomactionidentifier"
    let uploadRequest = UNNotificationRequest(identifier: uploadRequestIdentifier, content: uploadContent, trigger: trigger)
    UNUserNotificationCenter.current().add(uploadRequest, withCompletionHandler: nil)

推荐答案

首先：注册您的自定义操作：

Firstly: Register your custom actions:

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

    UNUserNotificationCenter.current().delegate = self
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) { (granted, error) in
        if granted {
         // Access granted
        } else {
         // Access denied
        }
    }

    self.registerNotificationAction()

    return true
}

func registerNotificationAction() {

    let first = UNNotificationAction.init(identifier: "first", title: "Action", options: [])
    let category = UNNotificationCategory.init(identifier: "categoryIdentifier", actions: [first], intentIdentifiers: [], options: [])
    UNUserNotificationCenter.current().setNotificationCategories([category])
}

并创建具有唯一标识符的内容：

And create a content with an unique identifier:

func scheduleNotification() {

    // Create a content
    let content = UNMutableNotificationContent.init()
    content.title = NSString.localizedUserNotificationString(forKey: "Some title", arguments: nil)
    content.body = NSString.localizedUserNotificationString(forKey: "Body of notification", arguments: nil)
    content.sound = UNNotificationSound.default()
    content.categoryIdentifier = "categoryIdentifier"

    // Create a unique identifier for each notification
    let identifier = UUID.init().uuidString

    // Notification trigger
    let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)

    // Notification request
    let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)

    // Add request
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)

}

最后：处理通知的默认值和自定义操作。

Lastly: Handle the notification with their default and custom actions.

   extension AppDelegate: UNUserNotificationCenterDelegate {

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

        if response.notification.request.content.categoryIdentifier == "categoryIdentifier" {

            switch response.actionIdentifier {
            case UNNotificationDefaultActionIdentifier:
                print(response.actionIdentifier)
                completionHandler()
            case "first":
                print(response.actionIdentifier)
                completionHandler()
            default:
                break;
            }
        }
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {

        completionHandler([.alert, .sound])
    }
}

结果如下：这将是我们的 UNNotificationDefaultActionIdentifier ：

Here's the results: This is going to be our UNNotificationDefaultActionIdentifier:

这个是通知的扩展版本，我们可以处理这两个动作：

And this one is expanded version of the notification, we could handle both actions:
