**6、测试**

ViewController.h

#import <UIKit/UIKit.h>
    #import <ZXingWidgetController.h>
    #import <QRCodeReader.h>
    
    @interface ViewController : UIViewController <ZXingDelegate>
    
    - (IBAction)scan:(id)sender;
    
    @end

将ViewController.m重命名为ViewController.mm

#import "ViewController.h"
    
    @interface ViewController ()
    
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
    }
    
    - (void)didReceiveMemoryWarning {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }
    
    - (IBAction)scan:(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];
        widController.soundToPlay =
        [NSURL fileURLWithPath:[mainBundle pathForResource:@"beep-beep" ofType:@"aiff"] isDirectory:NO];
        [self presentModalViewController:widController animated:YES];
        [widController release];
    }
    
    #pragma mark -
    #pragma mark ZXingDelegate
    - (void)zxingController:(ZXingWidgetController *)controller didScanResult:(NSString *)result {
        [self dismissModalViewControllerAnimated:YES];
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"结果" message:result delegate:nil cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alertView show];
        [alertView release];
    }
    
    - (void)zxingControllerDidCancel:(ZXingWidgetController *)controller {
        [self dismissModalViewControllerAnimated:YES];
    }
    
    @end

Build，报了1个错：'iostream' file not found

![24145238-97aa6671c7d245c8a1020b0e4a2799b1.png][]

解决方案：

重命名main.m为main.mm

重命名AppDelegate.m为AppDelegate.mm

再Build，报了31个错：Undefined symbols for architecture i386

解决方案：

自己创建的项目：

TARGETS -> Build Settings -> Apple LLVM compiler 4.1 - Language

设置C++ Standard Library的值为Compiler Default

ZXingWidget项目：

TARGETS -> Build Settings -> Architectures

设置Architectures的值为Standard(armv7, armv7s)
