使用CocoaPods

pod 'CardIO'

或者Demo下载https://github.com/AllLuckly/card.io-iOS-SDK
Xcode版本: Xcode 7.2.1

导入如下所示的库
Accelerate.framework

导入头文件

#import <CardIO.h>
#import <CardIOPaymentViewControllerDelegate.h>

// 需要签协议: CardIOPaymentViewControllerDelegate

- (void)click:(UIButton *)sender
{
    CardIOPaymentViewController *scanViewController = [[CardIOPaymentViewController alloc] initWithPaymentDelegate:self];
    // 进行简单的设置
    scanViewController.hideCardIOLogo = YES;
    scanViewController.collectCVV = NO;
    scanViewController.collectExpiry = NO;
    [self presentViewController:scanViewController animated:YES completion:nil];
}

Delegate

//取消扫描
- (void)userDidCancelPaymentViewController:(CardIOPaymentViewController *)scanViewController

{
    [scanViewController dismissViewControllerAnimated:YES completion:nil];

}

//扫描完成
-(void)userDidProvideCreditCardInfo:(CardIOCreditCardInfo *)info inPaymentViewController:(CardIOPaymentViewController *)scanViewController
{
    //扫描结果
    NSLog(@"Received card info. Number: %@, expiry: %02ld/%ld, cvv: %@.%@", info.cardNumber, (unsigned long)info.expiryMonth, (unsigned long)info.expiryYear, info.cvv);
    // 这里可以自己进行一些处理
    ///
    [scanViewController dismissViewControllerAnimated:YES completion:nil];
}
