How can I remove UIApplicationMain from an iPhone application?

I'm trying to port a game library over to the iPhone. Unlike SDL, this library doesn't take full control of your main() function, it's communicated with via quickly-returning functions from your own code. So, for example, obvious pseudocode: int main() { library_init(); // game init code here while(we_have_not_quit_the_game) { ...

Why am I crashing after MKMapView is freed if I'm no longer using it?

I have a MKMapView. Sometimes after my view controller is dismissed, I'll get a EXC_BAD_ACCESS. I turned on NSSZombies and it looks like the MKMapView's delegate — my view controller! — is being called, despite both the MKMapView and UIViewController subclass being freed. I've checked, and my memory management is correct. What's going ...
