- (void)viewDidLoad {
    [super viewDidLoad];

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.

    UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"2.png"] style:UIBarButtonItemStyleBordered target:self action:nil];
    self.navigationItem.rightBarButtonItem = btn;

    self.navigationItem.title = @"Contacts";

    sBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0,0,320,30)];
    sBar.delegate = self;

    [self.view addSubview:sBar];
    sBar.placeholder=@"Search";


    searchedData = [[NSMutableArray alloc]init];

    tableData = [[NSMutableArray alloc]init];

    [tableData addObjectsFromArray:dataSource]; 
}

我使用 Zbar SDK 并想在我的定义框架中扫描二维码和条形码，但它正在扫描屏幕的任何部分而不是我定义的框架，所以我在哪里做错了？我想在我定义的框架中进行这样的扫描。

这是我的代码。
