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
