【问题描述】：

我有一个推送通知的 ios 应用程序（例如当用户进入一个地理区域时）。 我还有一个手表应用程序，可以在 iPhone 锁定时收到这些通知。我在这些通知中有 2 个操作（“呼叫”、“转到”），它们正确显示在 Apple Watch 通知中，但是当用户触摸其中一个操作时，回调

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

我的 UNUserNotificationCenterDelegate 永远不会被调用！

这是 iOS 应用程序中的代码：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 

    // Register local notification (alert & sound)
    // They are used to notify the user when entering/exiting a monitored region
    UNUserNotificationCenter.current().delegate = self
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound], completionHandler:  (granted, error) in
        if let theError = error 
            NSLog("\(#function) error when request localNotification \(theError.localizedDescription)")
         else 
            if !granted 
                NSLog("\(#function) Warning local notification not granted")
            
        

     )

    var actions = [UNNotificationAction]()
    actions.append(UNNotificationAction(identifier: "CallId", title: "Call", options:[] )) // UNNotificationActionOptions.authenticationRequired
    actions.append(UNNotificationAction(identifier: "CallId2", title: "Go To", options:[UNNotificationActionOptions.authenticationRequired] ))

    let notificationCategory = UNNotificationCategory(identifier: "MonitoringRegionCategory", actions: actions, intentIdentifiers: [],  options: [])
    let categories: Set = [notificationCategory]
    UNUserNotificationCenter.current().setNotificationCategories(categories)
    return true

发送通知的代码（在 iOS 应用中）

    let content = UNMutableNotificationContent()
    content.title = "title"
    content.subtitle = "subtitle"

    var message:String
    if isEntering 
        message = String(format: NSLocalizedString("POI less than %d meters", comment: ""), Int(poi.poiRegionRadius))
     else 
        message = String(format: NSLocalizedString("POI more than %d meters", comment: ""), Int(poi.poiRegionRadius))
    

    content.body = message
    content.badge = 1
    content.sound = UNNotificationSound.default()
    content.categoryIdentifier = "MonitoringRegionCategory"
    let request = UNNotificationRequest(identifier: AppDelegate.LocalNotificationId.monitoringRegionId, content:content, trigger: nil)
    UNUserNotificationCenter.current().add(request, withCompletionHandler:  error in
        if let theError = error 
            NSLog("\(#function) Error with notification add \(theError.localizedDescription)")
        
    )

在WatchApp中以代码注册并实现UNUserNotificationCenterDelegate

class ExtensionDelegate: NSObject, WKExtensionDelegate, UNUserNotificationCenterDelegate 

    func applicationDidFinishLaunching() 
        NSLog("\(#function)")


        // Perform any final initialization of your application.
        UNUserNotificationCenter.current().delegate = self


  // MARK: UNUserNotificationCenterDelegate
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 
        NSLog("\(#function)")

        completionHandler()
    

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) 
        NSLog("\(#function)")
        completionHandler(.alert)
    

知道为什么当用户从通知中选择一个按钮时从不调用 userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 吗？

【问题讨论】：

您有没有在这个问题上得到答案或取得进展？我自己正在寻找有关这个确切问题的更多信息。

你有解决这个问题的办法吗？

一个发现 - 如果您点击通知而不是交互式按钮 Call，则将调用 didReceive 方法。由于某种原因，交互式按钮没有触发回调。

【参考方案1】：

我遇到了同样的问题，我通过将UNNotificationAction 添加为.foreground 类别来解决它。您必须更改以下行来修复它：

var actions = [UNNotificationAction]()
actions.append(UNNotificationAction(identifier: "CallId", title: "Call", options:[.foreground]))
actions.append(UNNotificationAction(identifier: "CallId2", title: "Go To", options:[.authenticationRequired]))

.foreground 将启动您的应用程序并调用func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 方法。您可以在此方法中为可操作按钮处理您的操作和重定向。示例如下：

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) 
     switch response.actionIdentifier.lowercased() 
        case "call":
            WKInterfaceController.reloadRootControllers(withNames: ["CallInterface"], contexts: nil)
        default: break
     
     completionHandler()

希望对你有帮助！

嘿 Bhanu，只是为了确认您的情况下的代表仍然是 ExtensionDelegate？因为我将它设置为前台，并且看起来不像 didReceive 被调用。
