iOS开发之OCR光学识别储蓄卡以及信用卡

最近由于公司需要一个扫描银行卡获取卡号的功能，网上找了很多相关的资料，完全扫描银行卡获取卡号信息的都是价格贵的不得了的，而且仅仅只是授权而已，在此咱退而求次，找到一个可以扫描信用卡的第三方框架，给大家伙分享一下，只能扫描信用卡……o.0。

框架的名字叫CardIO

在这里主要给大家演示一下怎么集成的，各位看官可得注意咯！我的xcode是7.1版本的，首先是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

再在TARGETS—Build Settings—Other Linker Flags中添加-ObjC和-lc++然后在我们需要调用的VC中导入头文件#import "CardIO.h"和#import "CardIOPaymentViewControllerDelegate.h"加上代理CardIOPaymentViewControllerDelegate

然后是实现的方法

OC版

-
(void)viewDidLoad
{

    [super
viewDidLoad];

 

    [CardIOUtilities
preload];

}

 

//开始调用扫描

-
(IBAction)begin:(id)sender
{

 

    CardIOPaymentViewController
*scanViewController
= [[CardIOPaymentViewController
alloc]
initWithPaymentDelegate:self];

 

    [self
presentViewController:scanViewController
animated:YES
completion:nil];

}

 

 

//取消扫描

-
(void)userDidCancelPaymentViewController:(CardIOPaymentViewController
*)scanViewController

 

{

 

 

    [scanViewController
dismissViewControllerAnimated:YES
completion:nil];

 

}

 

//扫描完成

-(void)userDidProvideCreditCardInfo:(CardIOCreditCardInfo
*)info
inPaymentViewController:(CardIOPaymentViewController
*)scanViewController

 

{

 

    //扫描结果

    NSLog(@"Received
card info. Number: %<a href="http://www.jobbole.com/members/uz441800">@,</a>
expiry: %02i/%i, cvv: %@.", info.redactedCardNumber, info.expiryMonth, info.expiryYear, info.cvv);

 

    [scanViewController
dismissViewControllerAnimated:YES
completion:nil];

 

}

SWIFT版

import
UIKit

 

class
ViewController:
UIViewController,
CardIOPaymentViewControllerDelegate
{

 

@IBOutlet
weak
var
resultLabel:
UILabel!

override
func viewDidLoad()
{

    super.viewDidLoad()

 

    CardIOUtilities.preload()

}

 

//开始调用扫描

@IBAction
func scanCard(sender:
AnyObject)
{

    let
cardIOVC
= CardIOPaymentViewController(paymentDelegate:
self)

    cardIOVC.modalPresentationStyle
= .FormSheet

    presentViewController(cardIOVC,
animated: true,
completion: nil)

}

//取消扫描

func
userDidCancelPaymentViewController(paymentViewController:
CardIOPaymentViewController!)
{

    resultLabel.text
= "user canceled"

    paymentViewController?.dismissViewControllerAnimated(true,
completion: nil)

}

//扫描完成

func
userDidProvideCreditCardInfo(cardInfo:
CardIOCreditCardInfo!,
inPaymentViewController
paymentViewController:
CardIOPaymentViewController!)
{

    if
let
info
= cardInfo
{

        let
str
= NSString(format:
"Received card
info.\\\\n Number: %@\\\\n expiry: %02lu/%lu\\\\n cvv: %@.",
info.redactedCardNumber,
info.expiryMonth,
info.expiryYear,
info.cvv)

        resultLabel.text
= str as
String

    }

        paymentViewController?.dismissViewControllerAnimated(true,
completion: nil)

    }  

}

到此就大功告成了，老外封装的东西还是非常给力的，希望可以找到扫描银行卡比较好用的第三方。

最终的效果，识别的非常准确哦
