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

OC版

Objective-C

- (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

Objective-C

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)
}
}

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

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
