Swift

func barcodeScanAndCount(_ controller: SBSDKBarcodeScanAndCountViewController, didDetectBarcodes codes: [SBSDKBarcodeScannerResult])

Parameters

`controller`	The calling SBSDKBarcodeScanAndCountViewController.
`codes`	Array of SBSDKBarcodeScannerResult containing the detected barcodes.


                    
                    
                    -barcodeScanAndCountController:filterResults:

                    filterResults:
                        (nonnull NSArray<SBSDKBarcodeScannerResult *> *)codes;

Swift

optional func barcodeScanAndCount(_ controller: SBSDKBarcodeScanAndCountViewController, filterResults codes: [SBSDKBarcodeScannerResult]) -> [SBSDKBarcodeScannerResult]

Parameters

`controller`	The calling SBSDKBarcodeScanAndCountViewController.

    barcodeScanAndCountController:
        (nonnull SBSDKBarcodeScanAndCountViewController *)controller
           polygonStyleForBarcode:(nonnull SBSDKBarcodeScannerResult *)code;

Swift

optional func barcodeScanAndCount(_ controller: SBSDKBarcodeScanAndCountViewController, polygonStyleForBarcode code: SBSDKBarcodeScannerResult) -> SBSDKScanAndCountPolygonStyle

Parameters

`controller`	The calling SBSDKBarcodeScanAndCountViewController.
`code`	Instance of SBSDKBarcodeScannerResult containing the detected barcode.

Return Value

The style to draw the polygon.


                    
                    
                    -barcodeScanAndCountController:overlayForBarcode:

    barcodeScanAndCountController:
        (nonnull SBSDKBarcodeScanAndCountViewController *)controller
                overlayForBarcode:(nonnull SBSDKBarcodeScannerResult *)code;

Swift

optional func barcodeScanAndCount(_ controller: SBSDKBarcodeScanAndCountViewController, overlayForBarcode code: SBSDKBarcodeScannerResult) -> UIView?

Parameters

`controller`	The calling SBSDKBarcodeScanAndCountViewController.
`code`	Instance of SBSDKBarcodeScannerResult containing the detected barcode.

Return Value

Overlay for the barcode as a UIView.
