我使用zbar SDK扫描二维码，任何人都可以帮我弄清楚如何使用zbar SDK添加市场和标签吗？

Answer 1

我为我的应用做了这样的事。

ZBarReaderViewController *reader = [ZBarReaderViewController new];
reader.cameraOverlayView = [self CommomOverlay];

-(UIView *)CommomOverlay{
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,480)];  
    UIImageView *TopBar = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,58)];
    [TopBar setImage:[UIImage imageNamed:@"topbar.png"]];
    [view addSubview:TopBar];

    UILabel *Toplabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 9, 300, 30)];
    [Toplabel setFont:[UIFont fontWithName:@"Arial-BoldMT" size:11]];
    [Toplabel setTextAlignment:UITextAlignmentCenter];
    [Toplabel setBackgroundColor:[UIColor clearColor]];
    [Toplabel setTextColor:[UIColor colorWithRed:76/255.0 green:76/255.0 blue:76/255.0 alpha:1.0]];
    [Toplabel setNumberOfLines:1];
    [Toplabel setText:@"Place  QR code inside the viewfinder to scan "];
    [TopBar addSubview:Toplabel];

    UIImageView *FrameImg = [[UIImageView alloc] initWithFrame:CGRectMake(60,150,193,170)];
    [FrameImg setImage:[UIImage imageNamed:@"frame.png"]];
    [view addSubview:FrameImg];
    return view;
}

你不会使用zbar，你只需要使用普通的Xcode标签。观看this教程，它很棒，并将教你如何使用标签。他们在教程中使用的Xcode版本可能有点旧。
