Overview

This category adds a single method to the Foundation framework’s NSCoder class. This method, decodeNXColor, is used to convert archived NXColor structures into NSColor objects.

NXColor, a type that dates from pre-OpenStep versions of NEXTSTEP, was a struct. Its replacement, NSColor, is a class. The difficulties of converting from a struct to a class require a special method like decodeNXColor.

The decodeNXColor method becomes part of the NSCoder class only for applications that use the Application Kit.

Tasks

Decoding NXColor Structures

Instance Methods

decodeNXColor

Decodes a color structure from NEXTSTEP Release 3 or earlier and returns an NSColor object.

- (NSColor *)decodeNXColor
Return Value

An autoreleased NSColor object. Returns nil if the archived color is invalid.

Discussion

This method does not have a matching method for encoding an NXColor structure. Encode an NSColor object instead.

Availability
  • Available in OS X v10.0 and later.
