CoreVideo.framework
QuartzCore.framework

    rc.supportedOrientationsMask = ZBarOrientationMaskAll;
    rc.readerDelegate = self;
    [self presentViewController:rc animated:YES completion:nil];

5.数据回传
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    NSLog(@"%@",info);
    id<NSFastEnumeration> results =
    [info objectForKey: ZBarReaderControllerResults];
    ZBarSymbol *symbol = nil;
    for(symbol in results)
        break;
    NSLog(@"%@",symbol.data);
