Is there any way to cause an app to quit instead of going to background when the home button is pressed? For security reasons, it would be better if the app did not run in background but actually closed when home is pushed. This is not for users' security, but rather for company data on the app, so it is not a user's choice. I could not find any way to quit other than forcing an exit, which Apple discourages.

A:
See opting out of background execution in the iphone application programming guide:
"If you do not want your application to remain in the background when it is quit, you can explicitly opt out of the background execution model by adding the UIApplicationExitsOnSuspend key to your application’s Info.plist file and setting its value to YES.
When an application opts out, it cycles between the not running, inactive, and active states and never enters the background or suspended states.
When the user taps the Home button to quit the application, the applicationWillTerminate: method of the application delegate is called and the application has approximately five seconds to clean up and exit before it is terminated and moved back to the not running state."
