Have you ever tried finding the lock icon you can see on Energy Savor system preference on your Mac?
I tried using it for my program, but I couldn’t find it. The reason I want to use it is to enforce root/admin privilege for changing some preference. So, it is quite suitable to use that icon.
I found out that how it can be used in the SFAuthorizationView class reference.
It is very interesting. Is there any other view class which draws an image for itself?
