How to know if the user force quit app?
===

In my mac application I am supporting full screen by changing system resolution of the device. And I am resetting back to old resolution if the user switches from full screen to windowed mode or if user quits the app and I need to handle force quit case also.  
1. Is there any API or callback which tells the application if the user presses cmd+opt+esc(force quit).  
2. Any other way to handle this?

I know in NSApplicaction there is an option to disable force quit([NSApplication setPresentationOptions: NSApplicationPresentationDisableForceQuit]) but instead of disabling it I want to handle force quit event.
