问题
I have an app that would get used by different clients with slight tweaks for each client, including a different icon and launch screen. Is it possible to program the app to grab those images off of a server and use them, or would I need to manually put them into each iteration of the app the normal way?
回答1:
It is impossible to change the App Icon programmatically using only public API as well as change launch screen at runtime. You may create some kind of "fake"-launch screen, that will be the first UIViewController in your app and will dismiss automatically short after being presented.
