Closest cocoa equivalent of enum

Is there a Cocoa class has similar functionality to enumerated values from C? I know that I can just use enums in Cocoa, but what if I want to put an enum in an NSArray (which only accepts objects)?

In Cocoa, global constants are usually used in place of enums in places where the values will logically be included in a collection. For example:

NSString * const HandTool = @"HandTool__InternalValue";
NSString * const BrushTool = @"BrushTool__InternalValue";
NSString * const EraserTool = @"EraserTool__InternalValue";

For example, all the NSAttributedString keys are enum-like, but are represented in this way.

An enum is just an integer type - you can wrap it in NSNumber to put it in an NSArray.
