An application should new permissions. How to force a view permissions to the user?

For this new version of my application, you need to add one more permission to the permission list authorized by the user.

Unfortunately, users already using the application you get can get new permission, so the requests fail. I know that they can remove the application and install it, but there's a way that you can force the re-authorization of permissions an application itself?

I am using iPhone SDK but since this is a fairly general question I ?????? here.

Thank you.
