CFStringLowercase(_:_:)

Declaration

func CFStringLowercase(_ theString: CFMutableString!, _ locale: CFLocale!)

Parameters

• theString:

  The string to be lowercased. If this value is not a CFMutableString object, an assertion is raised.

• locale:

  The locale to use when the lowercasing operation is performed. Prior to OS X v10.3 this parameter was an untyped pointer and not used.

  The locale argument affects the case mapping algorithm. For example, for the Turkish locale, case-insensitive compare matches “I” to “ı” (Unicode code point U+0131, Latin Small Dotless I), not the normal “i” character.

Discussion

The locale parameter type changed from void * to CFLocaleRef in OS X v10.3.
