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;
}
