我没有玩过它，但你应该看看 NSLinguisticTagger及其 - (NSOrthography *)orthographyAtIndex:(NSUInteger)charIndex effectiveRange:(NSRangePointer)effectiveRange 方法。来自NSOrthography docs :

The NSOrthography class describes the linguistic content of a piece of text, typically used for the purposes of spelling and grammar checking.

An NSOrthography instance describes:

Which scripts the text contains. A dominant language and possibly other languages for each of these scripts. A dominant script and language for the text as a whole. Scripts are uniformly described by standard four-letter tags (Latn, Grek, Cyrl, etc.) with the supertags Jpan and Kore typically used for Japanese and Korean text, Hans and Hant for Chinese text; the tag Zyyy is used if a specific script cannot be identified. See Internationalization Programming Topics for more information on internationalization.

Languages are uniformly described by BCP-47 tags , preferably in canonical form; the tag und is used if a specific language cannot be determined.
