//in ViewController.swift
@IBAction func didSavePreferences(segue: UIStoryboardSegue){
if let prefsVC = segue.source as? PreferencesTableTableViewController {
self.preferences = prefsVC.preferencesFromTableData()
print("Save button is tapped.")
updateLabels()
}
}
@IBAction func didCancelPreferences(segue:UIStoryboardSegue) {
print("Cancel button is tapped.")
}###in TableView Scene
Hook up the Cancel and Save buttons to their respective action methods. Ctrl-drag form the bar button to the exit object.
