CardIO无法获取我的卡信息

Question

我正在测试cardIO的iOS SDK用于扫描信用卡，我遵循了https://github.com/card-io/card.io-iOS-SDK中的说明，但我打开了我的CardIOPaymentViewController它没有扫描我的卡，没有回调到"userDidProvideCreditCardInfo：“否则当我取消控制器时"userDidCancelPaymentViewController：”被调用。我是不是漏掉了什么？

请注意，卡的位置正确，并且我使用的是Visa卡。

我的消息来源：

@interface TestViewController : UIViewController <CardIOPaymentViewControllerDelegate>

- (IBAction)scanCard:(id)sender;

@end

@implementation TestViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (IBAction)scanCard:(id)sender{
    CardIOPaymentViewController *scanViewController = [[CardIOPaymentViewController alloc] initWithPaymentDelegate:self];
    scanViewController.appToken = @"app-token";
    scanViewController.collectCVV = YES;
    scanViewController.collectExpiry = YES;
    scanViewController.useCardIOLogo = YES;
    [self.navigationController presentViewController:scanViewController animated:YES completion:nil];
}

- (void)userDidCancelPaymentViewController:(CardIOPaymentViewController *)scanViewController {
    NSLog(@"User canceled payment info");
    // Handle user cancellation here...
    [scanViewController dismissViewControllerAnimated: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: %02lu/%lu, cvv: %@.", info.redactedCardNumber, (unsigned long)info.expiryMonth, (unsigned long)info.expiryYear, info.cvv);
    // Use the card info...
    [scanViewController dismissViewControllerAnimated:YES completion:nil];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

致以问候。

这里是card.io的戴夫。

并非所有卡都能被card.io成功扫描。例如，最近的一些信用卡使用小的、非浮雕的数字，而不是card.io目前设计的传统的大的、凸起的数字。

尝试几种不同的卡，以确定这是否是特定于卡的问题。
