iOS 二维码扫描

https://github.com/bmorton/ZBarSDK

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> @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

- (IBAction)scan:(id)sender { ZBarReaderViewController * reader = [ZBarReaderViewController new]; reader.readerDelegate = self; ZBarImageScanner * scanner = reader.scanner; [scanner setSymbology:ZBAR_I25 config:ZBAR_CFG_ENABLE to:0]; reader.showsZBarControls = YES; [self presentViewController:reader animated:YES completion:nil]; } -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { id<nsfastenumeration> results = [info objectForKey:ZBarReaderControllerResults]; ZBarSymbol * symbol; for(symbol in results) break; _imageView.image = [info objectForKey:UIImagePickerControllerOriginalImage]; [picker dismissViewControllerAnimated:YES completion:nil]; _label.text = symbol.data; }
