Sadly I went to http://www.kochan-wood.com, and his site is down, I really hope this is temporary. Does anyone have any word on this? And does anyone possibly, just possibly, have all of the answers to "Programming in Objective-C" exercises on their harddrive? Edit: Here is the mirror provided by Stephen himself http://web.mac.com/steve_kochan/My_Home/Objective-C.html And I have also included the zip of the Objective-C and the normal C answers. And you can still PM me if you need to.
