In Objective-C from my understanding.

So I don’t even own a mac, my co-worker who sits behind me let me borrow his mac that he leaves in the office to learn. Luckily he had xcode already set up with the iPhone SDK. First thing I did was pick up a book, http://www.amazon.com/Beginning-iPhone-Development-Exploring-SDK/dp/1430216263 by apress. This book is great so far, [...]
