[Interest] Location when the App is Killed/Terminated/Suspended

[Jason H]

Oh, as far as I know, you can't unfortunately. 
You need your main() to be invoked so you can set the delegate, but the OS will use a non-derived delegate.

I'd love to know how to do this for iOS. In theory, it should be possible.
