1、首先要下载zxing2.0.zip;

下载库地址:

http://code.google.com/p/zxing/

    点击进入下载页    

2、解压压缩包

里面只保留  cpp  和 iphone 两个文件夹就可以了;然后创建项目zxingtest;把zxing-2.0拷贝到与你项目同级的目录下:


打开项目,导入ZXingWidget.xcodeproj文件,注意不要勾选copy,并且要选择refrence:



3、选择项目,build phases添加库:


4、设置Build Settings下的"header search paths":


5、在项目中引用文件

请把appdelegate.m文件改成adddelegate.mm,viewcontroller.m改成viewcontroller.mm文件,如果不改的话就有什么找不到文件的错误信息;

ViewController.xib文件如图:


ViewController.h:

#import <UIKit/UIKit.h>
#import "ZXingWidgetController.h"
#import "QRCodeReader.h" 
@interface ViewController : UIViewController<ZXingDelegate>{  
    UITextView *resultsView;  
    NSString *resultsToDisplay;  
}  
@property (retain, nonatomic) IBOutlet UITextView *resultsView;  
@property (nonatomic, copy) NSString *resultsToDisplay;  

- (IBAction)scanPressed:(id)sender;  

@end

ViewController.m:

//正常扫描退出事件  
- (void)zxingController:(ZXingWidgetController*)controller didScanResult:(NSString *)result {  
    self.resultsToDisplay = result;  
    if (self.isViewLoaded) {  
        [resultsView setText:resultsToDisplay];  
        [resultsView setNeedsDisplay];  
    }  
    [self dismissModalViewControllerAnimated:NO];  
    
    
}  
//扫描界面退出按钮事件  
- (void)zxingControllerDidCancel:(ZXingWidgetController*)controller {  
    [self dismissModalViewControllerAnimated:YES];  
}  

//扫描按钮事件  
- (IBAction)scanPressed:(id)sender   
{  
    ZXingWidgetController *widController = [[ZXingWidgetController alloc] initWithDelegate:self showCancel:YES OneDMode:NO];  
    QRCodeReader *qrcodeReader = [[QRCodeReader alloc] init];  
    NSSet *readers = [[NSSet alloc ] initWithObjects:qrcodeReader,nil];  
    [qrcodeReader release];  
    widController.readers = readers;  
    [readers release];  
    NSBundle *mainBundle = [NSBundle mainBundle];  
    //aiff  
    widController.soundToPlay =[NSURL fileURLWithPath:[mainBundle pathForResource:@"beep-beep" ofType:@"aiff"] isDirectory:NO];  
    [self presentModalViewController:widController animated:YES];  
    [widController release];  
} 

二维码测试:


还有,必须在真机上测试
