Hello, I studied Mac OS X programming with Cocoa for over a year now, in the extra time that I have from university. The book that I followed is Cocoa programming for Mac OS X - Aaron-Hillegass. The book was fine, and now I bought iOS programming, the big nerd ranch guide (again Aaron-Hillegass). But the problem here is that this book starts from basics, of things that I already know and I have to skip.I have to filter the important things.Also I would like to buy a book that doesn't write a lot of code, because I'm able to write code myself, rather I would read the explanation of things. For example: "to do this watch this class in the documentation and do the following procedure", with some code snippets but with a more free structure. Since I code a lot, having a book from where I have to copy the code isn't fun to me, I want to try it myself. So what book would you suggest, standing to your experience?
