    • sandbox
    completion @escaping (Result​<Data, NowPushError>) → Void Completion handler to execute after the token has been attempted to be registered.
    • Success: iOS push notification certificate.
    • Error: NowPushError - Information about the error that occurred when trying to register the token.
      Possible values:
      • decoding: Decoding error occurred.
      • httpRequestFailure: Generic error that is returned whenever the http call is not a success (2xx).

      environment: environment) { [weak self] result in
    guard let self = self else { return }
    switch result {
      case .success:
        UserDefaults.standard.set(true, forKey: "pushNotificationsRegistered")
        self.pushRegistrationState = .registrationSuccess
      case .failure:
        UserDefaults.standard.set(false, forKey: "pushNotificationsRegistered")
        self.pushRegistrationState = .registrationFailed
    }
  }
}

    表 : 5. Returns
    Type Description
    None

    This example shows how to unregister the push notification token associated with the TestPushApp application.

    func unregisterFromPushNotifications(deviceToken: Data) {
  pushService.unregisterPushToken(deviceToken, pushAppName: "TestPushApp", environment: environment) { [weak self] result in
    guard let self = self else { return }
    switch result {
      case .success:
        UserDefaults.standard.set(false, forKey: "pushNotificationsRegistered")
        self.pushRegistrationState = .unregisterSuccess
      case .failure:
        self.pushRegistrationState = .unregisterFailed
    }
  }
}

    NowPushService - payloadFromUserInfo(_userInfo: [AnyHashable: Any])

    Parses the userInfo key-value pairs into a NowPushPayload object.

    表 : 6. Parameters
    Name Type Description
    _userInfo [AnyHashable: Any] Push payload content received as part of the push notification.
    表 : 7. Returns
    Type Description
    Result<NowPushPayload, NowPushError> Returns the results of the payload parsing.
    • Success: Parsed NowPushPayload object.
    • Failure: NowPushError - Information about the error that was encountered while parsing the specified user payload.
      Possible values:
      • decoding: Decoding error occurred.
      • httpRequestFailure: Generic error that is returned whenever the http call is not a success (2xx).
      • notAuthorized: Requestor is not authorized to perform the specified push notification operation.
      • unsupportedData: Push payload is invalid.

    This example shows how to parser a user payload.

    func userNotificationCenter(_ center: UNUserNotificationCenter,
    didReceive response: UNNotificationResponse,
    withCompletionHandler completionHandler: @escaping () -> Void) {
  guard let pushService = pushService else {
    completionHandler()
    return
  }
  let userInfo = response.notification.request.content.userInfo
  _ = pushService.payloadFromUserInfo(userInfo)
    .flatMap(handleNowPushPayload)
}


func handleNowPushPayload(_ payload: NowPushPayload) -> Result<Void, NowPushError> {
  guard payload is NowPushVirtualAgent else {
    return .failure(NowPushError.unsupportedData)
  }
  launchVirtualAgent()
  return .success(())
