Hello guys
Well, i am an undergraduate student ,currently on second semester at Informatics University of my country, and until now we have given emphasis at C (use it for creating a simple game with some artificial intelligence with printf graphics ofc (lol) ) . So, by far i have no previous experience with object-oriented languages . Well, which book will you advise me to start learning obj.C ?
You have quite a few areas of study to work on.
First, there's OOP and OOD (Object oriented programming and Object oriented design.) This is a different way of thinking, and requires study to master. I would strongly suggest studying object oriented programming in university since you're there. You could use Objective C as the language you use to learn OOP, but I don't know of any university courses that teach OOP using Objective C. Java is much more common.
Then there is the objective C language. The books mentioned are a good start.
Next there are the iOS frameworks. Cocoa Touch is a big part of that, but there are also the foundation frameworks. Learning the iOS frameworks is a bigger job than learning Objective C, since Objective C is a relatively minor set of Object-Oriented extensions to C. It's a fairly small language. The iOS frameworks, however, are broad, deep, and very rich. It takes several years of intense study to learn them well. I've been doing iOS development since mid 2008, and full-time since the beginning of 2009, and did quite a bit of Mac OS development before that. There are still big chunks of the iOS frameworks I've never used. It's just the nature of the beast.
The good news is that the iOO frameworks are elegantly designed and internally consistent, so once you start to get the hang of the design philosophy, it makes sense. You can be productive in a few months, but don't expect true fluency to come quickly.
OpenGL is another big subject all on it's own. You need a solid grounding in 3D computer graphics, trig, matrix math/linear algebra, and probably a few other sub-discaplines in order to really handle OpenGL, and even then, the learning curve is VERY steep. The API is more low-level than the iOS frameworks, and require a strong understanding of C, pointers, etc.
