iphone - programmatically prevent app from running in background iOS

Question

I have an app that will run in the background but there is one case where I do not want that to happen, can I achieve this programmatically?

I know I can opt out by changing this plist value but what about at run time?

Answer 1

Add the variable UIApplicationExitsOnSuspend (Application does not run in background) to your applications plist and assign the value YES.
