I'd like to ask, if I want start learning how to develop iOS app, where should I begin? I've never programmed before. I read that most time it's developed in Objective-C code. So can I just start to learn this programming language or do I have to know any others from C language family, because I don't know if the basic "C" language is a base language and C++ and objective-C are extensions of that. Or if they are on the same level, just a "bit" different. Thank you for answers.
