iOS- 详解如何使用ZBarSDK集成扫描二维码/条形码，点我！

    //初始化相机控制器
    ZBarReaderViewController *reader = [ZBarReaderViewController new];

    //设置代理
    reader.readerDelegate = self;
    //基本适配
    reader.supportedOrientationsMask = ZBarOrientationMaskAll;
   
    //二维码/条形码识别设置
    ZBarImageScanner *scanner = reader.scanner;
   
    [scanner setSymbology: ZBAR_I25
                   config: ZBAR_CFG_ENABLE
                       to: 0];
    //弹出系统照相机，全屏拍摄
    [self presentModalViewController: reader
                           animated: YES];

     //初始化照相机窗口
    ZBarReaderView *readview = [ZBarReaderView new];

    //自定义大小
    readview.frame = CGRectMake(100, 100, 300, 300);
    //自定义添加相关指示.........发挥各自的APP的想象力
    //此处省略美化10000行代码...................
    //………………………..
    // 好进入正题—— 接着设置好代理
    readview.readerDelegate = self;
   
    //将其照相机拍摄视图添加到要显示的视图上
    [self.viewaddSubview:readview];
   
   
    //二维码/条形码识别设置
   ZBarImageScanner *scanner = readview.scanner;
   
   [scanner setSymbology: ZBAR_I25
                   config: ZBAR_CFG_ENABLE
                       to: 0];

   //启动，必须启动后，手机摄影头拍摄的即时图像菜可以显示在readview上
   [readview start];
