Class

NLLanguageRecognizer

The language of a body of text.

Declaration

@interface NLLanguageRecognizer : NSObject

Overview

The identification obtained from an NLLanguageRecognizer object can be either a single most likely language, access through dominantLanguage, or a set of language candidates with probabilities, using languageHypothesesWithMaximum:. You can reset the recognizer to its initial state, to be reused for new analysis.

Use the convenience method, dominantLanguageForString:, to get the most likely language without creating an NLLanguageRecognizer.
