If you're on 10.6 or later:
- (void)applicationWillTerminate:(NSNotification *)aNotification
{
NSRunningApplication* helperApp = [NSRunningApplication
runningApplicationsWithBundleIdentifier:@"bundle.id"];
[helperApp terminate];
}
Sadly, you can't send a terminate command if you're helper app is
sandboxed, so if you have to sandbox -- you'd likely need to reverse
the process.
Your helper app gets the NSRunningApplication object of your main app,
then observes the terminated property of it.
When you are notified of it terminating, you terminate yourself.
Another alternative, use the SMLoginItemsSetEnabled to launch and
terminate your helper app.
Don't think that was what the API was intended actually for, but when
you're stuck in a sandbox, you gotta make due with cheap plastic
shovel that you find in it.
