DigitalInkRecognizer
class DigitalInkRecognizer : NSObject
Objek untuk melakukan pengenalan tulis tangan pada tinta digital.
Tinta digital adalah representasi vektor dari apa yang telah ditulis pengguna. Model ini terdiri dari urutan
garis, masing-masing berupa urutan titik sentuh (koordinat dan stempel waktu). Lihat Ink untuk
spesifikasi
pendukung.

Pernyataan
Swift
class func digitalInkRecognizer(options: MLKDigitalInkRecognizerOptions) -> DigitalInkRecognizer
-
Melakukan pengenalan tinta input.
Perlu diperhatikan bahwa menggunakan recognize(ink:context:completion:) daripada metode ini dapat menyebabkan
akurasi dalam beberapa kasus.
Pernyataan
Swift
func recognize(ink: MLKInk) async throws -> MLKDigitalInkRecognitionResult
Parameter
ink
|
Input yang akan dikenali.
|
completion
|
|
-
Melakukan pengenalan tinta input menggunakan konteks pengenalan.
Konteks pengenalan berisi informasi tentang ukuran area tulisan, dan karakternya
yang telah dimasukkan ke dalam area teks. Hal ini membantu memperjelas kasus tertentu.
Contoh penggunaan: pengenalan sebelumnya telah menghasilkan string “hello”, yang telah disisipkan dalam
kolom teks. Kemudian, pengguna menulis tangan “dunia”. Kirimkan tinta yang menunjukkan “dunia” ke metode ini,
dan “hello” sebagai string dalam context. Pengenal kemungkinan besar akan menampilkan string “world”
dengan spasi di awal yang memisahkan kedua kata tersebut.
Lihat DigitalInkRecognitionContext untuk detailnya.
Pernyataan
Swift
func recognize(ink: MLKInk, context: MLKDigitalInkRecognitionContext) async throws -> MLKDigitalInkRecognitionResult
Parameter
ink
|
Input yang akan dikenali.
|
context
|
|
completion
|
Callback untuk menampilkan kandidat pengenalan. Lihat DigitalInkRecognizerCallback untuk mengetahui detailnya. Jika tidak ada yang dapat dikenali, daftar kosong
akan diteruskan ke callback.

This helps disambiguate certain cases.\n\n Example usage: a previous recognition has yielded the string \"hello\", that has been inserted in a\n text field. The user then handwrites \"world\". Send the present method the ink showing \"world\",\n and \"hello\" as a string in `context`. The recognizer will most likely return the string \" world\"\n with a leading space separating the two words.\n\n See [DigitalInkRecognitionContext](../Classes/DigitalInkRecognitionContext.html) for details. \n\n #### Declaration\n\n Swift \n\n func recognize(ink: MLKInk, context: MLKDigitalInkRecognitionContext) async throws -\u003e MLKDigitalInkRecognitionResult\n\n #### Parameters\n\n |--------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n | ` `*ink*` ` | Input to be recognized. |\n | ` `*context*` ` | See [DigitalInkRecognitionContext](../Classes/DigitalInkRecognitionContext.html) for details. |\n | ` `*completion*` ` | A callback for returning recognition candidates.
