I am just finishing the second semester of my CS degree. So far I learned C, all the fundamental algorithms and data structures (e.g., searching, sorting, linked lists, heaps, hash tables, trees, graphs, etc).
Next year we'll start with OOP, using either Java or C++.
Recently I got some ideas for some iPhone apps and got itchy to start working on them.
However I heard some bad things about Objectice-C in the past, so I am wondering if learning it as my first OOP language could be a problem. Not to mention that I think it will be hard to find books/online courses that teach basic OOP concepts using Objective-C to illustrate the concepts (as opposed to books using Java or C++, which are plenty), so this could be another problem.
In summary: should I start learning Objective-C and OOP concepts right now by my own, or wait one more semester until I learn Java/C++ at university and then jump into Objective-C?
Update: For those interested in getting started with OOP via Objective-C I just found some nice tutorials inside Apple's Developer Library -> http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/OOP_ObjC/Introduction/Introduction.html
