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

代码语言：javascript复制

- (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: %@, expiry: i/%i, cvv: %@.", info.redactedCardNumber, info.expiryMonth, info.expiryYear, info.cvv);

    [scanViewController dismissViewControllerAnimated:YES completion:nil];

}

SWIFT版

代码语言：javascript复制

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: lu/%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
