ZBarSDK，一个比较优秀的开源项目，使用起来也很简单。

ZBarSDK是一个开源的SDK，可从这里下载到源码，该SDK实现了识别和读取各种条形码，包括EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved 2 of 5 和 QR Code。

Step1.使用ZBarSDK 需要导入的framework

1.AVFoundation.framework

2.CoreMedia.framework

3.CoreVideo.framework

4.QuartzCore.framework

5.libiconv.dylib

Step2.在ViewController.h 导入#import "ZBarSDK.h"

Step3.在ViewController.h 继承 <ZBarReaderDelegate>协议

Step4.写代码：

ViewController.h

1

#import
 <uikit uikit.h="">

2

#import
 "ZBarSDK.h"

3

4

@interface
 ViewController : UIViewController <zbarreaderdelegate> @property (weak, nonatomic) IBOutlet UIImageView *imageView;

5

-
 (IBAction)scan:(id)sender;

6

@property
 (weak, nonatomic) IBOutlet UILabel *label;

@end</zbarreaderdelegate></uikit>

#import
 "ViewController.h"

#import
 "ZBarSDK.h"

@interface
 ViewController ()

    ZBarReaderViewController
 * reader = [ZBarReaderViewController new];

27

    reader.readerDelegate

28

    ZBarImageScanner
 * scanner = reader.scanner;

    [scanner

    reader.showsZBarControls

{

    ZBarSymbol
