Snippet of requirements from Udacity

Travel Locations MapWhen the app first starts it will open to the map view. Users will be able to zoom and scroll around the map using standard pinch and drag gestures.The center of the map and the zoom level should be persistent. If the app is turned off, the map should return to the same state when it is turned on again.Tapping and holding the map drops a new pin. Users can place any number of pins on the map.When a pin is tapped, the app will navigate to the Photo Album view associated with the pin.
