Cocoa in a Nutshell

Name

NSCharacterSet — Mac OS X 10.0

Synopsis

A character set represents a collection of Unicode characters. An instance of NSCharacterSet is a static entity; NSCharacterSet’s subclass NSMutableCharacterSet defines an interface to a dynamic set of Unicode characters.

NSCharacterSet is toll-free bridged with the Core Foundation type CFCharacterSet. As such, NSCharacterSet objects can be used interchangeably with the CFCharacterSet pointer type, CFCharacterSetRef.
