Hi Scott,

There are different notifications sent to an app, one of which is: 
- applicationWillTerminate: Tells the delegate when the app is about to terminate.

Monte’s http://mergext.com/home/mergnotify/ will help you get access to those notifications, although I don’t know for sure if it gets this one.

More info can be found here:

https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplication_Class/#//apple_ref/c/data/UIApplicationWillTerminateNotification

Mike Kerner’s suggestions may also work.

hth,

Steve MacLean
