SparkScan Settings

Defined in framework ScanditBarcodeCapture

SDCBatterySavingMode

Added in version 6.20.0

The battery saving mode to apply with SparkScan, off by default

SDCBatterySavingModeOn

Added in version 6.20.0

SparkScan will run with battery saving settings, for longer scanning sessions.

SDCBatterySavingModeOff

Added in version 6.20.0

SparkScan will be optimized for a faster scanning experience.

SDCBatterySavingModeAuto

Added in version 6.20.0

SparkScan will optimize battery usage depending on the phone temperature and battery level.

SDCSparkScanSettings
@interface SDCSparkScanSettings : NSObject

Added in version 6.8.0

Holds all the SparkScan settings, such as enabled symbologies and location selection.

For the settings to take effect, they must be applied to a SparkScan instance using SDCSparkScan.applySettings:completionHandler:.

By default, all types of barcodes (symbologies) are disabled. To scan barcodes, you need to manually enable all the symbologies you want to scan in your application.

The following lines of code show how to enable SDCSymbologyCode128 and apply the settings to SparkScan.

let settings = SparkScanSettings()
settings.set(symbology: .code128, enabled: true)
sparkScan.apply(settings, completionHandler: nil)
- initWithCapturePresets:
- (instancetype)initWithCapturePresets:(SDCCapturePreset)capturePresets

Added in version 6.19.0

Constructs new Spark Scan settings based on the provided presets, enabling relevant symbologies and optimizations. See SDCCapturePreset for more information on how to use capture presets.

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

Added in version 6.8.0

Get SDCSymbologySettings specific for the given SDCSymbology.

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

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

Added in version 6.8.0

Sets a 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 6.8.0

Retrieves the value of a previously set property. In case the property does not exist, -1 is returned.

codeDuplicateFilter
@property (nonatomic, assign) NSTimeInterval codeDuplicateFilter

Added in version 6.8.0

Determines the time interval in which codes with the same symbology/data are filtered out as duplicates. By default set to 700ms. Use this property to change the interval or completely turn off duplicate filtering:

  • Setting this property to value smaller than zero, means that the same code will not be reported again until the scanning has been stopped.

  • Setting this property to a value of zero means that the same code will be reported every time it is found.

  • Setting this property to a value larger than zero indicates the time that must pass between the same code to be reported again.

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

Added in version 6.8.0

Returns the set of enabled symbologies.

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

Added in version 6.8.0

Provides a convenient shortcut to enable/disable 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.

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

Added in version 6.8.0

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

singleBarcodeAutoDetection
@property (nonatomic, assign) BOOL singleBarcodeAutoDetection

Added in version 6.16.0

If true, when a single barcode is tracked, it will be automatically selected. Defaults to YES.

Note

This property works only when SparkScan is in target mode.

Deprecated since version 6.18: With the recent improvements introduced in the target mode, selection of barcodes is easier and more reliable. Given that, this method is outdated and not needed anymore.

locationSelection
@property (nonatomic, strong, nonnull) id<SDCLocationSelection> locationSelection

Added in version 6.16.0

Defines the strategy with which to select one out of many visible barcodes. See Location Selection Guide. By default, this property is nil and code selection is disabled.

Deprecated since version 6.19: With the introduction of smart configurations based on the scanning mode enabled by the users, the locationSelection property is not needed anymore and has been deprecated.

batterySaving
@property (nonatomic, assign) SDCBatterySavingMode batterySaving

Added in version 6.20.0

The battery saving mode to use with SparkScan. Default to Off, optimized for the fastest scanning experience.

NSStringFromBatterySavingMode(mode)
NSString *_Nonnull NSStringFromBatterySavingMode(SDCBatterySavingMode mode)

Added in version 6.21.0

SDCBatterySavingModeFromJSONString(JSONString, mode)
BOOL SDCBatterySavingModeFromJSONString(NSString *_Nonnull JSONString, SDCBatterySavingMode *_Nonnull mode)

Added in version 6.21.0
