NSValue
| NSValue | Mac OS X 10.0 |
This class provides an object-oriented interface to C and Objective-C scalar data items, such as numeric primitives, and C structures. Providing an object-oriented wrapper for these non-object types makes it possible for clients to store these types in any of the Foundation collection classes.
