Issue when killing an app in iOS simulator

Question

When I simulate my app on the iPad simulator (iOS 6) and simulate terminating the application, it takes me to a debug session within the main.m file. It highlights this method in green and says Thread 1: signal SIGKILL

int main(int argc, char *argv[]) {

 @autoreleasepool {
      return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
 }

}

When I go to run the app again (simulating terminating the app and reopening it again it brings me back to the viewController where I was when I killed the app, but it's completely frozen. Can't scroll, use the navigation toolbar or edit any text, etc etc. If I then go to the homescreen and back into the app again, I'm left with nothing but a blank black screen. Is there something I need to edit within the main.m file? I haven't touched anything in that file ever. Or is this potentially just how the simulator works?

Changes to main.m are not necessary, but you'll have to prepare your app for termination and re-set it when it comes alive again. See this documentation of the delegate methods. Esp. those described under "Monitoring App State Changes".
