Dev:Preferences.framework

This framework handles the interface and semantics for system preferences access and modification.


 * Preferences specifier plist format - the specification of the .plist files that specify the layout of an iOS preference pane.
 * PSSpecifier - a user-facing setting or actionable item in the Preferences framework.
 * PSRootController - an abstract class that represents the root controller in a Preferences-like application.
 * PSListController - a class that represents a list of preferences in a table.
 * PSDetailController - a view controller controlling a custom editing pane.
 * PSEditingPane - a subclass of UIView that provides custom code, instead of via PSSpecifiers, to manage the user interface.
