scannerDeviceView(_:didScanTo:fileData:error:)

Declaration

optional func scannerDeviceView(_ scannerDeviceView: IKScannerDeviceView!, didScanTo url: URL!, fileData data: Data!, error: (any Error)!)

Parameters

• scannerDeviceView:

  The scanner device that sent the message.

• url:

  The URL to save the data.

• data:

  The data from the scan.

• error:

  Any error encountered during the scan.

Discussion

This method is called when the scan has completed..

If the scannerDeviceView transferMode is IKScannerDeviceViewTransferMode.fileBased, the scan will have been saved at the specified url. The URL will be in the download directory and be a complete path, including a ‘sequence number’ if the file already exists.

If the scannerDeviceView transferMode is IKScannerDeviceViewTransferMode.memoryBased, the scanned data is contained in the data parameter. You can then take the action appropriate to your application.

In case of an error, the parameters (url and data) will be NULL and error (which may come directly from the scanner module / or the ImageCaptureCore framework) will describe why the scan or save failed.
