我是用ZBar做的二维码扫描 其他的SDK也可以
首先是导入库文件:
1.AVFoundation.framework
2.CoreMedia.framework
3.CoreVideo.framework
4.QuartzCore.framework
5.libiconv.dylib
这个5个库文件
在ViewController.h 导入#import "ZBarSDK.h" 并且 继承 <ZBarReaderDelegate>协议

@interface ViewController : UIViewController <zbarreaderdelegate> <br>@property (weak, nonatomic) IBOutlet UIImageView *imageView;- (IBAction)scan:(id)sender;@property (weak, nonatomic) IBOutlet UILabel *label; |
UIImageView/UILabel/UIButton, UIImageView 用于显示扫描到的图像，UILabel用于显示扫描到的信息，UIButton 用于响应事件
