Has anyone used an NSAuthorizationView? Can you please explain to me how it works?
You need to look this up in docs under SFAuthorizationView. I won’t make too many smart remarks, so as not to make NS of myself.
A link I just found: http://septicus.com/products/opensource/ purports to present an Objective-C wrapper around the Security framework. BSD license.
