I was in a similar situation a few years ago, but I opted for Monotouch [1]. I still had to learn UIKit, Foundation etc, but I didn't have to learn a "new" language. I did have to hack together a Visual Studio package to trick it into loading monotouch project files, but it was like 10 lines of code, and now you don't have to. I did spend several months developing (and shipping) two Objective-C apps for the few months that Apple banned Adobe AIR (and everything else along with it), and despite having spent 30 years programming, and a good part of that in C and C++, the full awfulness of ObjC was a surprise. But if all you've ever done is C#/WPF, ObjectiveC is going to be quite a shock. In fact there'll be a lot of cognitive dissonance. [1] http://xamarin.com/monotouch http://xamarin.com/monotouch
