How to start Mac OS X password screen

Question

I am building an application in Mac OS X which should bring up the password screen in Mac OS X once when a button on a QT WIndow is clicked. Which API I should use for this? Also, how will my application get notified whether system is locked or not?

Thanks in advance.

Answer 1

我相信您正在寻找Authorization Services API 。

This sounds a lot like an SFAuthorizationPluginView .

Apple has an API for you to add your own authentication methods. Here is some sample code to get started.
