class DigitalInkRecognizer : NSObject
Object to perform handwriting recognition on digital ink.
Digital ink is the vector representation of what a user has written. It is composed of a sequence
of strokes, each being a sequence of touch points (coordinates and timestamp). See
DigitalInkRecognizerobject using the specified options.
class func digitalInkRecognizer(options: MLKDigitalInkRecognizerOptions) -> DigitalInkRecognizer
Performs a recognition of the input ink.
Note that using
recognize(ink:context:completion:)instead of this method may lead to better accuracy in some cases.
func recognize(ink: MLKInk, completion: @escaping DigitalInkRecognizerCallback)
Input to be recognized.
A callback for returning recognition candidates. See
Performs a recognition of the input ink using a recognition context.
A recognition context contains information about the size of the writing area, and the characters that have already been entered in the text area. This helps disambiguate certain cases.
Example usage: a previous recognition has yielded the string “hello”, that has been inserted in a text field. The user then handwrites “world”. Send the present method the ink showing “world”, and “hello” as a string in
context. The recognizer will most likely return the string “ world” with a leading space separating the two words.
