1、CardIO识别
1.1 、CaedIO SDK下载
1.2、使用方法
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
1 // 导入头文件 2 #import "CardIO.h" 3 #import "CardIOPaymentViewControllerDelegate.h 4 5 // 遵守协议 6 <CardIOPaymentViewControllerDelegate>
1.3、主要方法
1、开始扫描银行卡
1 [CardIOUtilities preload]; 2 3 CardIOPaymentViewController *scanViewController = [[CardIOPaymentViewController alloc] initWithPaymentDelegate:self]; 4 5 [self presentViewController:scanViewController animated:YES completion:nil];
2、取消扫描
1 // CardIOPaymentViewControllerDelegate 协议方法 2 - (void)userDidCancelPaymentViewController:(CardIOPaymentViewController *)paymentViewController { 3 4 [[[UIAlertView alloc] initWithTitle:@"User cancelled sca" 5 message:nil 6 delegate:nil 7 cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show]; 8 9 [self dismissViewControllerAnimated:YES completion:nil]; 10 }
3、完成扫描
1 // CardIOPaymentViewControllerDelegate 协议方法 2 - (void)userDidProvideCreditCardInfo:(CardIOCreditCardInfo *)cardInfo inPaymentViewController:(CardIOPaymentViewController *)paymentViewController { 3 4 // 获取扫描结果 5 6 // 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 7 8 NSString *redactedCardNumber = cardInfo.cardNumber; // 卡号 9 NSUInteger expiryMonth = cardInfo.expiryMonth; // 月 10 NSUInteger expiryYear = cardInfo.expiryYear; // 年 11 NSString *cvv = cardInfo.cvv; // CVV 码 12 13 // 显示扫描结果 14 NSString *msg = [NSString stringWithFormat:@"Number: %@ expiry: %02lu/%lu cvv: %@", [self dealCardNumber:redactedCardNumber], expiryMonth, expiryYear, cvv]; 15 [[[UIAlertView alloc] initWithTitle:@"Received card info" message:msg delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil] show]; 16 17 [self dismissViewControllerAnimated:YES completion:nil]; 18 }
4、银行卡信息处理
1 // 对银行卡号进行每隔四位加空格处理,自定义方法 2 - (NSString *)dealCardNumber:(NSString *)cardNumber { 3 4 NSString *strTem = [cardNumber stringByReplacingOccurrencesOfString:@" " withString:@""]; 5 NSString *strTem2 = @""; 6 7 if (strTem.length % 4 == 0) { 8 9 NSUInteger count = strTem.length / 4; 10 for (int i = 0; i < count; i++) { 11 NSString *str = [strTem substringWithRange:NSMakeRange(i * 4, 4)]; 12 strTem2 = [strTem2 stringByAppendingString:[NSString stringWithFormat:@"%@ ", str]]; 13 } 14 15 } else { 16 17 NSUInteger count = strTem.length / 4; 18 for (int j = 0; j <= count; j++) { 19 20 if (j == count) { 21 NSString *str = [strTem substringWithRange:NSMakeRange(j * 4, strTem.length % 4)]; 22 strTem2 = [strTem2 stringByAppendingString:[NSString stringWithFormat:@"%@ ", str]]; 23 } else { 24 NSString *str = [strTem substringWithRange:NSMakeRange(j * 4, 4)]; 25 strTem2 = [strTem2 stringByAppendingString:[NSString stringWithFormat:@"%@ ", str]]; 26 } 27 } 28 } 29 30 return strTem2; 31 }
