Hello guys, I have a little problem here. I have a tough time deciding on how to learn Objective-C: whether I spend 700 dollars on mac or download GNUstep library for linux. The thing is though, I am going to university next year and I am not sure if I will have time to learn Objective-c, at the same time, I would like to know how close GNUstep is following Cocoa API so I can follow one good tutorial I found, which looks at main language and some parts of the framework. Can anyone give advice on this issue? Thanks and merry Xmas guys!!!
