ios 二維碼掃描

標籤：

我是用ZBar做的二維碼掃描 其他的SDK也可以

首先是匯入庫檔案:

1.AVFoundation.framework

2.CoreMedia.framework

3.CoreVideo.framework

4.QuartzCore.framework

5.libiconv.dylib

這個5個庫檔案

在ViewController.h 匯入#import "ZBarSDK.h" 並且 繼承 <ZBarReaderDelegate>協議

123	@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 用於顯示掃描到的映像，UILabel用於顯示掃描到的資訊，UIButton 用於響應事件

- (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;}
