iOS iPhone ZBar获取扫描图像

Question

如何让ZBar不仅可以返回一个条形码文本字符串，而且还可以扫描条形码的UIImage？

Answer 1

包括在实现ZBarReaderDelegate类是这样的：

- (void) imagePickerController: (UIImagePickerController*) reader 
didFinishPickingMediaWithInfo: (NSDictionary*) info 
{ 
    // ADD: get the decode results 
    id<NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults]; 
    ZBarSymbol* symbol = nil; 

    for (symbol in results) 
    { 
     // grab first barcode 
     break; 
    } 

    // do something with barcode data 
    qrCode.text = symbol.data; 

    // do something with barcode image 
    // BELOW IS HOW YOU GET THE SCANNED IN IMAGE 
    // 
    resultImage.image = [info objectForKey: UIImagePickerControllerOriginalImage]; 

    // dismiss controller 
    [reader dismissModalViewControllerAnimated: YES];
