In this chapter, you modified the Add New Journal Entry screen so that the user can add their current location to a new journal entry. Next, you created a MapViewController class and configured it to display a custom map region centered on your location. Then, you updated the JournalEntry class to conform to the MKAnnotation protocol. After that, you modified the MapViewController class to display a pin for each journal entry within the map region. You configured the pins to display callouts and configured buttons in the callouts to display the Journal Entry Detail screen when tapped. Finally, you modified the JournalEntryViewController class to display a map snapshot for the journal entry on the Journal Entry Detail screen.
