how to set UIPickerView's current selection.

Question

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?

Answer 1

Store the selection when you hop away from the XIB, and when you come back in just tell it to reselect.
