I have a picker View in one xib file, and a map View in another. The user selects a map view with the picker View, and the clicks a button, which loads the mapView. However, when I return to the picker View xib file, the picker View goes back to the default selection. How do I make the picker view automatically select the mapView that the user selected before?
Store the selection when you hop away from the XIB, and when you come back in just tell it to reselect.
