SBSDKUIBarcodeScannerViewControllerDelegate

@protocol
    SBSDKUIBarcodeScannerViewControllerDelegate <SBSDKUIViewControllerDelegate>

Delegate protocol for ‘SBSDKUIBarcodeScannerViewController’.

  • Informs the delegate that one or more barcodes have been detected.

    Implementing this delegate function will use the new Scanbot barcode detector: see ‘SBSDKBarcodeType’.

    Declaration

    Objective-C

    - (void)qrBarcodeDetectionViewController:
            (nonnull SBSDKUIBarcodeScannerViewController *)viewController
                        didDetectResults:
                            (nonnull NSArray<SBSDKBarcodeScannerResult *> *)
                                barcodeResults;

    Swift

    optional func qrBarcodeDetectionViewController(_ viewController: SBSDKUIBarcodeScannerViewController, didDetect barcodeResults: [SBSDKBarcodeScannerResult])

    Parameters

    viewController

    The detection view controller that detected barcode(s).
    barcodeResults

    An array of SBSDKBarcodeScannerResult objects containing recently detected barcodes.

  • Informs the delegate about capturing barcode image. Fires only if barcodeImageGenerationType behavior parameter is not SBSDKBarcodeImageGenerationTypeNone

    Implementing this delegate function will use the new Scanbot barcode detector: see ‘SBSDKBarcodeType’.

    Declaration

    Objective-C

    - (void)qrBarcodeDetectionViewController:
            (nonnull SBSDKUIBarcodeScannerViewController *)viewController
                  didCaptureBarcodeImage:(nullable UIImage *)barcodeImage
                                imageURL:(nullable NSURL *)imageURL;

    Swift

    optional func qrBarcodeDetectionViewController(_ viewController: SBSDKUIBarcodeScannerViewController, didCaptureBarcodeImage barcodeImage: UIImage?, imageURL: URL?)

    Parameters

    viewController

    The detection view controller that detected barcode(s).
    barcodeImage

    A device-orientation-corrected barcode image.
    imageURL

    URL, where frameImage is saved. Stored in default storage of SBSDKUIPageFileStorage.

  • Optional: informs the delegate that the ‘SBSDKUIBarcodeScannerViewController’ has been cancelled and dismissed.

    Declaration

    Objective-C

    - (void)qrBarcodeDetectionViewControllerDidCancel:
    (nonnull SBSDKUIBarcodeScannerViewController *)viewController;

    Swift

    optional func qrBarcodeDetectionViewControllerDidCancel(_ viewController: SBSDKUIBarcodeScannerViewController)

    Parameters

    viewController

    The ‘SBSDKUIBarcodeScannerViewController’ that did dismiss.

  • Optional: informs the delegate that the ‘SBSDKUIBarcodeScannerViewController’ has been cancelled and dismissed by timeout.

    Declaration

    Objective-C

    - (void)qrBarcodeDetectionViewControllerDidTimeout:
    (nonnull SBSDKUIBarcodeScannerViewController *)viewController;

    Swift

    optional func qrBarcodeDetectionViewControllerDidTimeout(_ viewController: SBSDKUIBarcodeScannerViewController)

    Parameters

    viewController

    The ‘SBSDKUIBarcodeScannerViewController’ that did dismiss. Note: If this method is not implemented, viewController will try to call -(void)qrBarcodeDetectionViewControllerDidCancel:(nonnull SBSDKUIBarcodeScannerViewController *)viewController
