SDL_GetWindowWMInfo can give you a struct containing the underlying UIWindow* created by SDL_CreateWindow on iOS (check out SDL_syswm.h).

I *highly* recommend using SDL 2.0.4 or later for iOS - much of the platform backend code has been rewritten since 2.0.3, and many parts of it didn’t work on modern iOS versions prior to the rewrites.
