-(Void) ImagePickerController :( UIImagePickerController *) picker didFinishPickingMediaWithInfo :( NSDictionary *) info

{

Id <NSFastEnumeration> results = [info objectForKey: ZBarReaderControllerResults];

ZBarSymbol * symbol;

For(Symbol in results)

Break;

_ ImageView. image = [info objectForKey: UIImagePickerControllerOriginalImage];

[Picker dismissViewControllerAnimated: YES completion: nil];
