The Settings Bundle editor in XCode (New->File->iOS->Resource->Settings Bundle) seems like a convenient tool for rapidly specifying a large range of user interfaces other than just user preferences. Is there any way to use this tool and the .plist mechanism for declaratively specifying user interfaces in general, rather than just for user defaults?
In other words, can I create a settings bundle (but not for settings) and programmatically load it from my application bundle and have iOS generate a view (and controller?) from it within my application?
It sounds like you want something like In App Settings Kit. This will let you make a settings page identical to the iphone one but inside your app.
