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-lc++

然后在我们需要调用的VC中导入头文件
#import "CardIO.h"
#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: %@, 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
