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
