[SDL] iOS Background Event

[Jeremy Jurksztowicz]

As far as I can tell there is a SDL_WINDOW_MINIMIZED event put on the queue,
but I never actually checked to see if that gets to the event loop before
the minimization occurs. I just added my own callback at the point of
minimization in the SDL library, ie in SDL_uikitappdelegate.m:

void (*SDL_IOS_LowMemory)  () = NULL;

void (*SDL_IOS_WillResign) () = NULL;

void (*SDL_IOS_DidResume)  () = NULL;


They are called in the various cocoa callbacks, and then in my code I have:


extern "C" void low_memory ( ) {...}

extern "C" void suspend ( ) {...}

extern "C" void resume ( ) {...}

//...

SDL_IOS_MemoryHook = low_memory;

SDL_IOS_WillResign = suspend;

SDL_IOS_DidResume = resume;


Pretty hacky, but the version I was working with had no way to present a
memory warning at all, so I decided to add the minimize callbacks while I
was there.


There was a thread a while back about adding a new API for platform
settings, similar to the GL attribute API. Anyways, Good Luck!
