tags(in:scheme:options:tokenRanges:)
Returns an array of linguistic tags and token ranges for a given string range.
Declaration
func tags(in range: NSRange, scheme tagScheme: String, options opts: NSLinguisticTagger.Options = [], tokenRanges: AutoreleasingUnsafeMutablePointer<NSArray?>?) -> [String]Parameters
- range:
The range from which to return tags.
- tagScheme:
The tag scheme. See Nslinguistictagscheme for possible values.
- opts:
The linguistic tagger options to use. See Options for possible values.
- tokenRanges:
Returns by reference an array of token ranges.
Return Value
An array of the tags in the requested range.
Discussion
When the returned array contains an entry that doesn’t have a corresponding tag scheme, that entry is an empty string ("").
This is a convenience method for calling tags(in:unit:scheme:options:tokenRanges:) and passing NSLinguisticTaggerUnit.word as the linguistic unit.
