最近由于公司需要一個掃描銀行卡獲取卡號的功能，網上找了很多相關的資料，完全掃描銀行卡

獲取卡號信息的都是價格貴的不得了的，而且僅僅只是授權而已，在此咱退而求次，找到一個可

以掃描信用卡的第三方框架，給大家伙分享一下，只能掃描信用卡......o.0。

框架的名字叫CardIO

在這里主要給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，首先是把框架整個拉進自己的工程，然后在

TARGETS---Build Phases---Link Binary With Libraries

里邊分別加入下面這幾個框架

Accelerate.framework

MobileCoreServices.framework

CoreMedia.framework

AudioToolbox.framework

AVFoundation.framework

再在TARGETS---Build Settings---Other Linker Flags中添加-ObjC和-lc++

然后在我們需要調用的VC中導入頭文件#import "CardIO.h"和#import "CardIOPaymentViewControllerDelegate.h"

加上代理CardIOPaymentViewControllerDelegate

然后是實現的方法

OC版

- (void)viewDidLoad {
    [super viewDidLoad];

    [CardIOUtilities preload];
}

//開始調用掃描
- (IBAction)begin:(id)sender {

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

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


//取消掃描
- (void)userDidCancelPaymentViewController:(CardIOPaymentViewController *)scanViewController

{


    [scanViewController dismissViewControllerAnimated:YES completion:nil];

}

//掃描完成
-(void)userDidProvideCreditCardInfo:(CardIOCreditCardInfo *)info inPaymentViewController:(CardIOPaymentViewController *)scanViewController

{

    //掃描結果
    NSLog(@"Received card info. Number: %@, 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()
}

//開始調用掃描
@IBAction func scanCard(sender: AnyObject) {
    let cardIOVC = CardIOPaymentViewController(paymentDelegate: self)
    cardIOVC.modalPresentationStyle = .FormSheet
    presentViewController(cardIOVC, animated: true, completion: nil)
}
//取消掃描
func userDidCancelPaymentViewController(paymentViewController: CardIOPaymentViewController!) {
    resultLabel.text = "user canceled"
    paymentViewController?.dismissViewControllerAnimated(true, completion: nil)
}
//掃描完成
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，老外封裝的東西還是非常給力的，希望可以找到掃描銀行卡比較好用的第三方。

最終的效果，識別的非常準確哦
