当通过推送通知接收时，AnyHashable:Any 不会转换为 swift 中的字典

Question

  func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        startSavingNotification(userInfo: userInfo)
        completionHandler(UIBackgroundFetchResult.newData)
        //TODO: TEST
        //showTestPushAlert(userInfo: userInfo)
    }
    //Fire Test notification
    func startSavingNotification(userInfo:[AnyHashable : Any]) {
        //Fetch Payload Dict
        if let payloadDict = userInfo["payload"] as? Dictionary<String,Any> {
            savePushNotification(payloadDict: payloadDict)
        }
    }

func showTestPushAlert(userInfo:[AnyHashable : Any]) {
    let alert = UIAlertController(title:"", message: "\(userInfo)", preferredStyle: .alert)
    let cancelButton = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
    alert.addAction(cancelButton)
    UIApplication.topViewController()?.present(alert, animated: true, completion: nil)
}

当我尝试在警报中显示数据时，此用户信息看起来像这样：

如果条件为假，请在此处做错事：?? 如果让 payloadDict = userInfo["payload"] 作为？字典{ savePushNotification（payloadDict：payloadDict） }

Answer 1

   //This method will parse push notification userinfo data
    func parseNotification(userInfo: [AnyHashable: Any]) {
        print(">>>parseNotificationCalled ")
        if let notification = userInfo["payload"] as? String,
            let jsonData = notification.data(using: .utf8),
            let dict = try? JSONSerialization.jsonObject(with: jsonData, options: .allowFragments) as? NSDictionary {
            //This is the point where we need to save push notification
            savePushNotification(payloadDict: dict ?? [:])
            print("APS PAYLOAD DICTIONARY \(dict)")
        }

在我的例子中，有效载荷字典以字符串格式出现。已解决。

AnyHashable:Any doesn't convert to dictionary in swift when receives through push notification
