Hiding Data From A UITableView

I have an application that uses a table view and displays data from a .plist file. The data is of locations throughout an area in the city, based on suburb. The app never goes online for data. The groups are entered in a NSArray which contains a number of suburbs in them, getting its data from an item in the .plist file. I plan on using settings in my application, and having them in the Settings.app. The settings will consist of just PSToggleSwitchSpecifiers defaulted to on/YES. What is the best way of taking the data from the Settings.bundle and using them to manipulate a UITableView?

Help with some sample code would be appreciated.
