I’m looking to create a grouped style UITableView that allows a user to select different options (like shown below). I’m already able to setup the UITableView in a grouped style; my question is based on how I can add buttons, toggles and list options like shown below? Is it possible to make use of plist’s to simplify the process somewhat?

Note: I’m not trying to create a ‘settings’ view, I want to allow users to create lots of different NSDictionaries and set values on each of them using the table setup described.
You should create your own UITableViewCell. This way you could add the desired UI items of your choice. You could use the Interface builder to create your custom cell. There are many good tutorials on the subject.
I do not see the need to use a property list for this, since it is rather simple to implement this.
This is a good example:
