1、CardIO 识别

• 框架 GitHub

• 配置

  • 1、把框架整个拉进自己的工程，然后在 TARGETS => Build Phases => Link Binary With Libraries 里边分别加入下面这几个框架。

    Accelerate.framework    MobileCoreServices.framework    CoreMedia.framework    AudioToolbox.framework    AVFoundation.framework

    

  • 2、在TARGETS => Build Settings => Other Linker Flags 中添加 -ObjC 和 -lc++ 。

    

  • 3、在 iOS8 + 系统中使用相机需要在 Info.plist 中添加 Privacy - Camera Usage Description，并设置其值。

    

  • 4、在我们需要调用的文件中导入

    // 导入头文件    #import "CardIO.h"    #import "CardIOPaymentViewControllerDelegate.h    // 遵守协议    
            

• 开始扫描银行卡

  [CardIOUtilities preload];    CardIOPaymentViewController *scanViewController = [[CardIOPaymentViewController alloc] initWithPaymentDelegate:self];    [self presentViewController:scanViewController animated:YES completion:nil];

• 取消扫描

  // CardIOPaymentViewControllerDelegate 协议方法    - (void)userDidCancelPaymentViewController:(CardIOPaymentViewController *)paymentViewController {        [[[UIAlertView alloc] initWithTitle:@"User cancelled sca"                                     message:nil                                     delegate:nil                           cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show];        [self dismissViewControllerAnimated:YES completion:nil];    }

• 扫描完成

  // CardIOPaymentViewControllerDelegate 协议方法    - (void)userDidProvideCreditCardInfo:(CardIOCreditCardInfo *)cardInfo inPaymentViewController:(CardIOPaymentViewController *)paymentViewController {        // 获取扫描结果        // cardNumber 是扫描的银行卡号，显示的是完整号码，而 redactedCardNumber 只显示银行卡后四位，前面的用 * 代替了，返回的银行卡号都没有空格        NSString *redactedCardNumber = cardInfo.cardNumber;     // 卡号        NSUInteger expiryMonth = cardInfo.expiryMonth;          // 月        NSUInteger expiryYear = cardInfo.expiryYear;            // 年        NSString *cvv = cardInfo.cvv;                           // CVV 码        // 显示扫描结果        NSString *msg = [NSString stringWithFormat:@"Number: %@\n\n expiry: %02lu/%lu\n\n cvv: %@", [self dealCardNumber:redactedCardNumber], expiryMonth, expiryYear, cvv];        [[[UIAlertView alloc] initWithTitle:@"Received card info" message:msg  delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show];        [self dismissViewControllerAnimated:YES completion:nil];    }

  // 对银行卡号进行每隔四位加空格处理，自定义方法    - (NSString *)dealCardNumber:(NSString *)cardNumber {        NSString *strTem = [cardNumber stringByReplacingOccurrencesOfString:@" " withString:@""];        NSString *strTem2 = @"";        if (strTem.length % 4 == 0) {            NSUInteger count = strTem.length / 4;            for (int i = 0; i < count; i++) {                NSString *str = [strTem substringWithRange:NSMakeRange(i * 4, 4)];                strTem2 = [strTem2 stringByAppendingString:[NSString stringWithFormat:@"%@ ", str]];            }        } else {            NSUInteger count = strTem.length / 4;            for (int j = 0; j <= count; j++) {                if (j == count) {                    NSString *str = [strTem substringWithRange:NSMakeRange(j * 4, strTem.length % 4)];                    strTem2 = [strTem2 stringByAppendingString:[NSString stringWithFormat:@"%@ ", str]];                } else {                    NSString *str = [strTem substringWithRange:NSMakeRange(j * 4, 4)];                    strTem2 = [strTem2 stringByAppendingString:[NSString stringWithFormat:@"%@ ", str]];                }            }        }        return strTem2;    }
