用戶通知請求總是帶有默認動作標識符

Question

我正在使用UNUserNotificationCenterDelegate（> ios 10）和其中一個委託方法，其中我可以檢查來自通知的響應總是actionIdentifier等於「com.apple.UNNotificationDefaultActionIdentifier」無論如何我做的事。 「response.notification.request.content.categoryIdentifier」是正確的，具有期望值，但request.actionIdentifier永遠不會正確（下面示例中的「mycustomactionidentifier」）。有誰知道我是否錯過了一些東西？

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() 
    } 
} 

我添加了動作和類別的通知中心：

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

和我發送請求把正確的標識符：

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)

首先：註冊您的自定義操作：

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]) 
} 

，並創建一個唯一的標識符的內容：

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 an 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) 

} 

最後：處理與它們的默認和自定義操作的通知。

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]) 
    } 
} 

希望它有幫助！

這裏的結果：這將是我們的UNNotificationDefaultActionIdentifier：

而這一次擴大了通知的版本中，我們可以處理兩個動作：

正如Mannopson所說，您可以註冊一個默認的動作標識符。 不過我以爲你需要的是另一件事：

response.notification.request.identifier

從Apple's actionIdentifier description說這個參數可以包含一個你UNNotificationAction對象之一的標識符，或者它可能包含一個系統定義的標識符。這意味着你需要註冊一個，希望我是正確的（因爲我是一個快速新手）
