Question

Right now, I have an application with a single map view. What should I do to stop the app from retrieving new location updates once I hit the home button. My goal is to make that arrow next to the battery symbol disappear when on the main menu page. The app will launch again when the user brings it back to the foreground. This is what I have so far, but it’s not working.

- (void)applicationDidEnterBackground:(UIApplication *)application
{
    exit(0);
}

1. What you have should work (in fact, I have used it once for debugging purposes).

2. However, you should not do that, despite the fact that it works. Simply set the UIApplicationExitsOnSuspend key in the Info.plist file of your application to true.
