Question

我正在使用card.io_ios_sdk_3.8.0，我完全遵循https://github.com/card-io/card.io-iOS-SDK中提到的内容。我无法扫描信用卡或借记卡（VISA，Discover等）。

我得到＆＃34; NSScanner：nil字符串参数＆＃34;。

我知道我犯了一个错误，但我不知道如何跟踪它。有没有国家？

      - (IBAction)scanCard:(id)sender
      {
              CardIOPaymentViewController *scanViewController = [[CardIOPaymentViewController alloc] initWithPaymentDelegate:self];
              scanViewController.appToken = @"<I have entered my app token>"; // get your app token from the card.io website
              [self presentViewController:scanViewController animated:YES completion:nil];
       }

        - (void)userDidProvideCreditCardInfo:(CardIOCreditCardInfo *)info inPaymentViewController:(CardIOPaymentViewController *)scanViewController 
       {
             // The full card number is available as info.cardNumber, but don't log that!
             NSLog(@"Received card info. Number: %@, expiry: %02i/%i, cvv: %@.",           info.redactedCardNumber, info.expiryMonth, info.expiryYear, info.cvv);
            // Use the card info...

           if(info.cardNumber!=Nil && ![info.cardNumber isEqualToString:@""] && !      [info.cardNumber isKindOfClass:[NSNull class]])cardNumber.text = info.cardNumber;
           if(info.cvv!=Nil && ![info.cvv isEqualToString:@""] && ![info.cvv isKindOfClass:[NSNull class]])cvvno.text = info.cvv;
           if(info.expiryMonth!=0)[self getCorrectMonth:[NSString stringWithFormat:@"%02i",info.expiryMonth]];
           if(info.expiryYear!=0) year.text = [NSString stringWithFormat:@"%i",info.expiryYear];

           [scanViewController dismissViewControllerAnimated:YES completion:nil];
        }

我不确定，它是否与正确添加的确认相关。

不使用card.io扫描信用卡/借记卡
