How to simplify in app Application Settings management?

Question

I'm sure every cocoa-touch programmer had to face this: I know Apple would like every application to place their settings in the Settings app. But it's quite limiting in what it offers, in terms of customization. Also, it's better to place some settings within the app, as they change frequently.
In such cases, the developer has to implement settings management within its own application. The thing is that it's quite an overkill to reimplement all the basic stuff that could be easily managed in the Settings app with a simple plist. Is there some kind of framework/library that has already been created to simplify things, that maybe could take as an input a similar plist?
In general, how do you implement in app-settings? Do you override UITableViewControllers each time?

Answer 1

Have you seen mySettings? Uses almost the same plist file as you can use in the Settings app but displays it inside your app.

Incidentally, Apple recommends including frequently changed settings inside your application. Other stuff should be in the Settings app.
