title: Pass Data to UINavigationController Partent
body: <p>I've got a VC (root) that calls a Modal Segue to a UINavigatioController (settings). The user can change what they want. How do I let the first VC (root) know that the changes are done. the UINav's delegate is the (root) VC. any ideas to pass data back from a modal segue? cheers</p>
