I am currently reading a great book I found on iPhoneclub.nl called “Apps maken voor de iPhone” by developer Koen Pijnenburg. It’s in Dutch and explains all the basics for developing iPhone apps. Since the iPad has the same operating system the basics are the same for both devices.
The book expects that the reader already has a couple of years of programming experience in an object oriented language. I bought it because I read in a review that it explains Objective-C very well and since I didn’t know the language yet and it is required for developing on iOS that would come in handy…
There are very useful courses on iTunesU about programming for iPhone/iPad: http://itunes.apple.com/WebObjects/MZStore.woa/wa/viewPodcast?id=395605774
I watched it myself for my job during the summer holidays.
Hm that one looks more up to date then the one I have from dev.apple.com. It is also from iTunes U but there it is about the “new” iOS 3.0 which is kind of outdated by now 🙂
So thank you for the link!
