                    -qrBarcodeDetectionViewController:didDetectResults:

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.


                    
                    
                    -qrBarcodeDetectionViewController:shouldHighlightResult:

Asks the delegate whether to highlight a barcode on the selection overlay or not. Only called only when the selection overlay is enabled.

Declaration

Objective-C

- (BOOL)qrBarcodeDetectionViewController:
            (nonnull SBSDKUIBarcodeScannerViewController *)viewController
                   shouldHighlightResult:
                       (nonnull SBSDKBarcodeScannerResult *)code;

Swift

optional func qrBarcodeDetectionViewController(_ viewController: SBSDKUIBarcodeScannerViewController, shouldHighlight code: SBSDKBarcodeScannerResult) -> Bool

Parameters

`viewController`	The calling SBSDKUIBarcodeScannerViewController.
`code`	The barcode scanner result that may be highlighted or not.

Return Value

YES, if the provided barcode result should be highlighted on the selection overlay. NO otherwise.


                    
                    
                    -qrBarcodeDetectionViewControllerDidCancel:

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.


                    
                    
                    -qrBarcodeDetectionViewControllerDidTimeout:

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
