NSKeyedUnarchiver — Mac OS X 10.2

Synopsis

This concrete subclass of NSCoder provides a means to decode objects that have been encoded in a keyed archive. The companion class NSKeyedArchiver provides the means to create such keyed archives from a set of objects. Archiving is described in greater detail in Chapter 2.
