iPhone Contacts App and Delegates


in iphone contacts app, favorites section starts empty table view , fills favorite contacts select them round rect button in different view controller, located on tab.

how happen?

understand array object updated contact object when 'add contact favorite' selected, how object pass backwards through view heirarchy? if view not on screen, view , it's objects not allocated , don't exist in memory. how can modify array if isn't instatiated?

thanks
