Question

我正在使用CardIOPaymentViewController将card.io集成到我的应用程序中。但是，每当我启动并显示视图控制器时，它总是进入手动输入屏幕。相机屏幕从未启动。我在Xcode＆＃34; NSScanner：nil string argument＆＃34;。

中看到了这个日志

我还试图打印CardIOUtilities.canReadCardWithCamera（）的输出，它总是返回false。

任何有关问题的线索都会受到赞赏吗？

以下是代码：

//Callback when card is scanned correctly

        //dismiss scanning controller
        paymentViewController?.dismissViewControllerAnimated(true, completion: nil)

        //Send to Stripe
        getStripeToken(card)


    }
}

}

在我的应用程序中集成了Card.IO ios sdk但无法让它扫描卡片
