iOS - Card Identification 银行卡号识别

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.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
    	<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;
  	}
