MLKitDigitalInkRecognition Framework Reference

  • MLKDigitalInkRecognitionModel represents a downloadable recognition model for use with DigitalInkRecognizer.

  • Models are downloaded to the device and unzipped upon first use, impacting initial recognition speed.

  • This class includes immutable properties of the recognition model, while DigitalInkRecognitionContext handles ink-specific properties.

  • You must create an instance using initWithModelIdentifier: with a valid DigitalInkRecognitionModelIdentifier.

MLKDigitalInkRecognitionModel


@interface MLKDigitalInkRecognitionModel : MLKRemoteModel

Represents a downloadable recognition model.

Recognition models are downloaded on the device when the download method is called. The downloaded model is unzipped when DigitalInkRecognizer loads it at inference time for the first time, which makes the first recognition a bit slower than subsequent ones.

This object contains properties that are constant throughout the lifetime of a recognition model.

See DigitalInkRecognitionContext for the properties that depend on the ink being recognized.

  • Identifier of this recognition model.

    Declaration

    Objective-C

    @property (nonatomic, readonly) MLKDigitalInkRecognitionModelIdentifier *_Nonnull modelIdentifier;

  • Not available. Use init(modelIdentifier:) instead.

    Declaration

    Objective-C

    - (nonnull instancetype)init;

  • Creates a new instance from the specified model identifier.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithModelIdentifier:
    (nonnull MLKDigitalInkRecognitionModelIdentifier *)modelIdentifier;

    Parameters

    modelIdentifier

    A valid DigitalInkRecognitionModelIdentifier.

    Return Value

    A new DigitalInkRecognitionModel instance.
