UITextInputTokenizer
A tokenizer, which is an object that allows the text input system to evaluate text units of different granularities.
Declaration
@MainActor protocol UITextInputTokenizer : NSObjectProtocolOverview
Granularities of text units are always evaluated with reference to a storage or reference direction.
Text-processing objects that conform to the UITextInput protocol must hold a reference to a tokenizer (through the tokenizer property). The UITextInputStringTokenizer class provides a default base implementation of the UITextInputTokenizer protocol. Tokenizers of this class are suitable for most western-language keyboards. Apps with different requirements may adopt the UITextInputTokenizer protocol and create their own tokenizers.
