ios - 如何在诗丽吉中使用 TouchID

Question

我正在我的应用程序中使用触摸 ID 探索 Sirikit 以进行付款。在函数句柄中，我调用了触摸 ID 函数，但我在 siri UI 中出现黑屏，如果有什么方法可以帮助我。

func handle(intent: INSendPaymentIntent, completion: @escaping (INSendPaymentIntentResponse) -> Void) {
        guard let payee = intent.payee, let amount = intent.currencyAmount else {
        return completion(INSendPaymentIntentResponse(code: .unspecified, userActivity: nil))
        }
            LAContext().evaluatePolicy(.deviceOwnerAuthentication, localizedReason: "Allow siri to do the Payment", reply:
               {(accessGranted:Bool, error:Error?) -> Void in
                   if (accessGranted){
                       print("Sending \(amount) payment to \(payee)!")
                        completion(INSendPaymentIntentResponse(code: .success, userActivity: nil))
                    }
           })
        print("Sending \(amount) payment to \(payee)!")
        completion(INSendPaymentIntentResponse(code: .success, userActivity: nil))
    }
