With iOS development I've typically had the interviews that you are seeking. I show them my apps over coffee and then I do a few hours (or a feature) of contract work (paid) for them and it usually works out and I continue onwards :)
I am not sure that this works for all situations though; maybe I've been lucky too... I tend to work for smaller startups.
