1、CardIO 识别

• 框架 GitHub 下载地址

• 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.frameworkMobileCoreServices.frameworkCoreMedia.frameworkAudioToolbox.frameworkAVFoundation.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<CardIOPaymentViewControllerDelegate>

• 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;}
