【iOS QR Code】集成ZXingWidget（XCode Version 4.5.2，iOS 6.0 SDK）

1、添加ZXingWidget
打开目录ZXing/iphone/ZXingWidget，将ZXingWidget.xcode文件拖拽添加到项目中




2、设置Link Binary With Libraries
TARGETS -> Build Phases -> Link Binary With Libraries
点击+，添加libZXingWidget.a




3、设置Target Dependencies
TARGETS -> Build Phases -> Target Dependencies
点击+，添加ZXingWidget




4、设置Header Search Paths
TARGET -> Build Settings -> Search Paths -> Header Search Paths
添加ZXing/iphone/ZXingWidget/Classes相对路径，选择recursive
添加ZXing/cpp/core/src相对路径，选择non-recursive




5、导入iOS框架
TARGETS -> Build Phases -> Link Binary With Libraries
点击+，添加***Foundation、AudioToolbox、CoreVideo、CoreMedia、libiconv、AddressBook和AddressBookUI




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];
}
