You could add Action<MyRowClass> as an ivar of your table source. When you create your table source set that ivar to a corresponding method or lambda in your edit dialog thingy. Instead of show alert, you would do (ivar name)(selected row) to fire the action on your edit dialog.
A more IOSish way would be to create an interface (protocol) for your table source, co taint a method like "ContactWasSelected(MyRowClass contact)", implement the interface in your editor, make an ivar in your table source for the interface and proceed as in the previous example. If you like tight coupling, make an ivar of type "my Editor class" in your table source and set it to the instance of your editor. Call methods on the class directly. If what you mean about "because its a class" is that you don't have an editor instance lying around, just pick one of the above strategies only tie it to a method on your listviewcontroller and have that controller create and present the editor interface. Lots of ways to attack your problem - I'd probably go with the Action<> method for the sake of expediency. Delegate/protocol/interface is good if your table source needs to call back for more than one thing.
