Is there a way to check when a user has shutdown/closed my app?
I want to save some data when this happens and I'm not sure if there's a way to do it.

3Don't delete. Some searches will land on your question which will help people by pointing them in the right direction. – Black Frog Apr 20 '15 at 11:59

How on earth are those duplicates? This seems to ask how to detect if a user KILLS an app. That is just to detect if a user LEAVES an app. – Daniel Springer May 20 '20 at 16:18

Yes, you can do this in - (void)applicationWillTerminate:(UIApplication *)application method of the AppDelegate.
Save data, user settings in this method.

When a user closes the app, - (void)applicationWillTerminate:(UIApplication *)application gets called, which is located in the AppDelegate. You can do the needful in that.
