SBSDKUIBarcodeScannerViewControllerDelegate

@protocol
    SBSDKUIBarcodeScannerViewControllerDelegate <SBSDKUIViewControllerDelegate>

Delegate protocol for ‘SBSDKUIBarcodeScannerViewController’.


                    
                    
                    -qrBarcodeDetectionViewController:didDetect:

Informs the delegate that a QR or bar code has been detected.

Implementing this delegate function will use the barcode detector provided natively by iOS: see AVMetadataObjectType.

Caution: This API will soon be deprectated.

Declaration

Objective-C

- (void)qrBarcodeDetectionViewController:
            (nonnull SBSDKUIBarcodeScannerViewController *)viewController
                               didDetect:
                                   (nonnull SBSDKMachineReadableCode *)code;

Swift

optional func qrBarcodeDetectionViewController(_ viewController: SBSDKUIBarcodeScannerViewController, didDetect code: SBSDKMachineReadableCode)

Parameters

`viewController`	The detection view controller that detected the QR or bar code.
`code`	The detected QR or bar code.


                    
                    
                    -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).
`results`	An array of SBSDKBarcodeScannerResult objects containing recently detected barcodes.


                    
                    
                    -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
