Hey all, I bought the Kochan book but I am having trouble with this code: http://classroomm.com/objective-c/index.php?topic=683.0 It is for chp3 3.1 When I try to compile it I get 3962 errors of: error: expected identifier or '(' before '-' token They are all on: -(void) print; -(void) setNumerator: (int) n; -(void) setDenominator: (int) d; Is something wrong with my xcode? I typed it in just like the book has listed and also tried a copy / paste from that site. Any ideas? My book is not the 2.0 version but I have the pdf of the 2.0 version. It looks like there are a lot of differences between the two. (Especially on this section) My book has it using the Object.h header and nothing about NSObject or NSLog. So I will go ahead and order the 2.0 book like everyone recommended.
