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
下载地址
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

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];}

    resultLabel.text= "user canceled"

    paymentViewController?.dismissViewControllerAnimated(true, completion: nil)

}

//扫描完成

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

    iflet 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= stras 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
