Defined in framework ScanditBarcodeCapture

@interface SDCBarcodeTrackingSettings : NSObject <NSCopying>

Added in version 6.0.0

+ settings#
+ (instancetype)settings

Added in version 6.0.0

Creates a new barcode tracking settings instance. All symbologies are disabled. Make sure to enable the symbologies required by your app before applying the settings to SDCBarcodeTracking with SDCBarcodeTracking.applySettings:completionHandler:.

- settingsForSymbology:#
- (nonnull SDCSymbologySettings *)settingsForSymbology:(SDCSymbology)symbology

Added in version 6.0.0

Get SDCSymbologySettings specific for the given SDCSymbology.

Note that modifying the returned object doesn’t automatically apply the changes to SDCBarcodeTracking. After you made changes to the symbology settings, call SDCBarcodeTracking.applySettings:completionHandler: with these SDCBarcodeTrackingSettings to apply them.

@property (nonatomic, nonnull, readonly) NSSet<NSNumber *> *enabledSymbologies

Added in version 6.0.0

Returns the set of enabled symbologies.

- enableSymbologies:#
- (void)enableSymbologies:(nonnull NSSet<NSNumber *> *)symbologies

Added in version 6.0.0

This function provides a convenient shortcut to enabling decoding of particular symbologies without having to go through SDCSymbologySettings. By default, all symbologies are turned off and symbologies need to be explicitly enabled.

- setSymbology:enabled:#
- (void)setSymbology:(SDCSymbology)symbology

Added in version 6.0.0

This function provides a convenient shortcut to enabling/disabling decoding of a particular symbology without having to go through SDCSymbologySettings.


Some 1d barcode symbologies allow you to encode variable-length data. By default, the Scandit Data Capture SDK only scans barcodes in a certain length range.

If your application requires scanning of one of these symbologies, and the length is falling outside the default range, you may need to adjust the active symbol counts for the symbology in addition to enabling it.

- setValue:forProperty:#
- (void)setValue:(id)value
     forProperty:(NSString *)property

Added in version 6.0.0

Sets property to the provided value. Use this method to set properties that are not yet part of a stable API. Properties set through this method may or may not be used or change in a future release.

- valueForProperty:#
- (nullable id)valueForProperty:(NSString *)property

Added in version 6.0.0

Retrieves the value of a previously set property. In case the property does not exist, nil is returned.
