BarcodeScanner is used as a library within a project, there are four classes available for use:
ATGOverlayViewThis class wraps ZXing’s
OverlayViewwith custom drawing for the scanning view.ATGBarcodeScannerViewControllerThis class wraps ZXing’s
ZXingWidgetControllerthat manages the scanning view.ATGBarcodeScannerHandlerThis class is an interface used to obtain a single instance of the scanner.
ATGBarcodeScannerHandlerDelegateThis class is an interface for callback handling from the scanner/parser. The class that initializes the scanning process is responsible for ensuring that the delegate implements and register the instance using
ATGBarcideScannerHandler.
Search by sku.repositoryId is supported, so the BarcodeScanner simply returns the scanned barcode and lets the main app handle the search/rendering of the parsed result.
ATGOverlayView Interface
// Values: OneD, TwoD, DataMatrix - enum BarcodeScannerMode // Parameter pModes is NOT mutually exclusive. That is, passed in values can be OR'd together. - (id)initWithModes:(BarcodeScannerMode)pModes;
ATGBarcodeScannerViewController Interface
(id)initWithDelegate:(id<ZXingDelegate>)delegate modes:(BarcodeScannerMode)pModes;
ATGBarcodeScannerHandler Interface
// Handler is a singleton value. However, the delegate can be updated/changed by invoking this method with the desired callback listener. + (ATGBarcodeScannerHandler *)initWithDelegate:(id<ATGBarcodeScannerHandlerDelegate>)pDelegate; // Launches the scanner screen that handles the scanning/parsing of barcodes. // Method invoker is responsible for presenting the returned view controller. - (ATGBarcodeScannerViewController *)performBarcodeScan;
ATGBarcodeScannerHandlerDelegate Interface
The callback handler is responsible for dealing with the passed in view controller, including dismissing it.
- (void)didSuccessfullyParseScan:(ParsedResult *)pParsedResult withController:(UIViewController *)pViewController; - (void)didCancelScanRequest:(UIViewController *)scannerViewController;
