Answer 1

Sorry Unfortunately Apple not provide any method that user Uninstall app from user's device, There is no such method.

When user delete any application device does give the alert "Do you want to delete this application" with option "Delete" and "Cancel". You don't have to write any specific code for this.

I just assume that There is one method in which you can find out when user is about to delete your app. That is you need to implement push notification Apple server will inform you when you try to push to an uninstalled instance. Other than that there's no way to detect it but i am not sure its helpful or not.
