Examples

Here are a few example of options you could have some interest in.

Camera orientation

The device orientation might be a little tricky to manage. If your app (Or the scanning screen) supports multiple interface orientation it's advised to re-instantiate the scanner in the transition delegate

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
        coordinator.animate(alongsideTransition: { (v) in
            //Remove smartscanner and nil it
        }) { (v) in
            //Add it again
        }
}

Camera focus

You might to change the region of focus of the camera using continuousFocus. For example :

    override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {        
        if let coordinatesInPreviewView = touches.first?.location(in: self.preview) {
            scanner?.continuousFocus(at: coordinatesInPreviewView)
        }
    }

Video Stream modifications

In some circonstance it might be interesting to do a few changes on the stream configuration.

//Changeing the zoom factor
scanner?.setNewZoomFactor(CGFloat( newZoomValue ))

//Some device supports a better framerate
scanner?.setCameraFramerate(60)

Simulator support

Indeed the camera is not supported in the simulator. But you can still simulate a SmartScanResult using the smartScanShouldReturnResultCodefunction.

Decoding behavior fine tuning

There is two parameters that might allow you to adjust how/when SmartScan will return you the results.

• setSmartScannerResultBehavior Will allow you to always return found values, to only return when the result has changed or stop trying to scan if a result is found
• enableMultipleResultsConfirmation Can be useful, mainly on contents that don't have any checksum, to ensure the result is more accurate (Mainly car license plates). Setting it to 4 , for example, will ensure that the code has been confirmed and read 4 times before validating it and returning it. Of course it make it a little slower.
