MBDetectionRecognizerRunnerViewControllerDelegate Protocol Reference


                    
                    
                    -recognizerRunnerViewController:didFinishDetectionWithDisplayableQuad:

Called when Scanning library finishes detection of objects. Detection cycle happens before recognition cycle and it attempts to find the location of specific object on an image. Since detection and recognition are two separate events, it is possible for detection to be successful while recognition can fail (not vice versa).

NOTE: This method is called on background processing thread. Make sure that you dispatch all your UI API calls to main thread.

Returned MBDisplayableQuadDetection object.

Declaration

Objective-C

- (void)recognizerRunnerViewController:
            (nonnull UIViewController<MBRecognizerRunnerViewController> *)
                recognizerRunnerViewController
    didFinishDetectionWithDisplayableQuad:
        (nonnull MBDisplayableQuadDetection *)displayableQuad;

Swift

optional func recognizerRunnerViewController(_ recognizerRunnerViewController: Any!, didFinishDetectionWithDisplayableQuad displayableQuad: MBDisplayableQuadDetection)

Parameters

`recognizerRunnerViewController`	scanningViewController recognizer runner view controller responsible for scanning
`displayableQuad`	displayable quad object detection containing information of detection (i.e. location)


                    
                    
                    -recognizerRunnerViewController:didFinishDetectionWithDisplayablePoints:

Called when Scanning library finishes detection of objects. Detection cycle happens before recognition cycle and it attempts to find the location of specific object on an image. Since detection and recognition are two separate events, it is possible for detection to be successful while recognition can fail (not vice versa).

NOTE: This method is called on background processing thread. Make sure that you dispatch all your UI API calls to main thread.

Returned MBDisplayablePointsDetection object.

Declaration

Objective-C

- (void)recognizerRunnerViewController:
            (nonnull UIViewController<MBRecognizerRunnerViewController> *)
                recognizerRunnerViewController
    didFinishDetectionWithDisplayablePoints:
        (nonnull MBDisplayablePointsDetection *)displayablePoints;

Swift

optional func recognizerRunnerViewController(_ recognizerRunnerViewController: Any!, didFinishDetectionWithDisplayablePoints displayablePoints: MBDisplayablePointsDetection)

Parameters

`recognizerRunnerViewController`	scanningViewController recognizer runner view controller responsible for scanning
`displayablePoints`	points object detection containing information of detection (i.e. location)


                    
                    
                    -recognizerRunnerViewControllerDidFailDetection:

Called when Scanning library fails to detect any object with any of the currently active recognizers.

NOTE: This method is called on background processing thread. Make sure that you dispatch all your UI API calls to main thread.

Declaration

Objective-C

- (void)recognizerRunnerViewControllerDidFailDetection:
    (nonnull UIViewController<MBRecognizerRunnerViewController> *)
        recognizerRunnerViewController;

Swift

optional func recognizerRunnerViewControllerDidFailDetection(_ recognizerRunnerViewController: Any!)

Parameters


                                recognizerRunnerViewController

Recognizer runner object responsible for scanning
