How can I iterate over a class keys in objective-C?

Question

How can I iterate over an instance properties in objective-C ?

I need to get all the properties values without having to specify them.

This is the only solution I've found so far, but I was wondering if it could be done with less code: Get an object properties list in Objective-C

thanks

I mean the properties, and I used the term "key" in the context of Key-Value Coding — aneuryzm, Aug 23 '11 at 10:05

EDIT : @EmptyStack has the right idea - follow his link in the comments on the question :)

Take a look at these methods : http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ObjCRuntimeRef/Reference/reference.html#//apple_ref/c/func/class_copyPropertyList

They let you (amongst other things) find all the properties that a class implements. You can then run through that array of properties and call performSelector: for each property you are interested in.
