Instance Method

matches(in:options:range:)

Returns an array containing all the matches of the regular expression in the string.

Declaration

func matches(in string: String, options: NSRegularExpression.MatchingOptions = [], range: NSRange) -> [NSTextCheckingResult]

Parameters

string

The string to search.

options

The matching options to use. See NSRegularExpression.MatchingOptions for possible values.

range

The range of the string to search.

Return Value

An array of NSTextCheckingResult objects. Each result gives the overall matched range via its range property, and the range of each individual capture group via its range(at:) method. The range {NSNotFound, 0} is returned if one of the capture groups did not participate in this particular match.

Discussion

This is a convenience method that calls enumerateMatches(in:options:range:using:) passing the appropriate string, options, and range.
