I'm a former iOS developer and even I don't care enough to save a couple dollars by compiling my own app, when I could get auto updates from the app store. I don't suspect it'll hurt your sales with customers too much in that sense because they aren't making this choice. I'd think more about other developers taking your code, slightly theming it differently, and selling it in the app store for a dollar less than you. If you're ok with that, then go ahead. And no license in the world will help simply because you actually have to mount a legal challenge, and who's going to pay for that? I'd say a better strategy to scratch your OSS itch is to make the underlying libraries OSS, but not the UI, that way you have some kind of value proposition you're offering.
