'Locked' settings approach
<p>I am planning to use the standard Setting application to manage most of my application's settings.  However, I need a way to lock some of those settings from being changed (perhaps in a child settings view) without authenticating through a PIN screen.  My research has led me to conclude that this isn't possible with the standard Settings application.  True?</p>

<p>Seems like I will need to create my own ScreenLockView (it appears that I can not make use of the build-in one) that controls access to a TableView of settings, where the settings are a serialized NSDictionary stored in the sandbox.  Does seems like a reasonable approach?</p>

<p>Thanks for your time and thoughts.</p>
