银行卡号自动识别

1、CardIO识别

1.1 、CaedIO SDK下载

下载地址

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: %@\n\n expiry: %02lu/%lu\n\n 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     }
