Removed private API use that was causing AppStore rejection Pavel Kanzelsberger to SDL I tried to submit a SDL application to the Mac AppStore and it got rejected because SDL cocoa is using a Private (non-public) API. Problematic part is here: SDL_cocoaevents.m @implementation NSApplication(SDL) - (void)setRunning { _running = 1; } @end Symbol _running in NSApplication is private and shouldn't be used. Any ideas what could I do about this?
