All of the new tables in this application that show places or photos or tags must be driven by Core Data. It is your responsibility to determine the schema which best supports your needs.

This task is already fulfilled in the other tasks especially task #3 and task #4.

You are not required to provide any UI for users to create new Virtual Vacations (see Extra Credit #1 if you want to), so simply create a single Virtual Vacation called “My Vacation” in the user’s Documents directory somewhere in your code. All “visits” and “unvisits” will happen in this “My Vacation” Virtual Vacation. However, just because you do not have to provide UI to create new vacations does not mean you are exempted from any other required tasks which support multiple Virtual Vacations (like Required Task #1). You may well want to create some other Virtual Vacations anyway just to verify that the rest of your code deals properly with multiple of them.

This task is already fulfilled in the other tasks by the functionality of the VacationHelper and tested using the debug database.

The Tag Search tab must bring up a list of all the tags found in all the photos that the user has chosen to be a part of this Virtual Vacation (sorted with most-often-seen first). Touching on a tag brings up a list of all the photos in the Virtual Vacation that have that tag. The tags in a Flickr photo dictionary are contained in a single, space- separated, all lowercase string (accessible via the FLICKR_TAGS key). Separate out and capitalize each tag (not all caps, just capitalize the first letter) so that they look nicer in the UI. Don’t include any tags that have a colon in them.

In both storyboards add an additional table view controller as well as an subclass for it. Create a push segue from the tags cell from the vacation view controller to the new controller and from its cell a another push segue to the vacation-photos table view controller. Adjust the cell reuse identifier and set the identifiers for the two new segues.

The Itinerary tab must show a list of all the places where photos in the chosen Virtual Vacation have been taken (sorted with first-visited first). Clicking on a place will show all the photos in the Virtual Vacation taken in that place. The place name should be the one returned by getting the new FLICKR_PHOTO_PLACE_NAME key in the Flickr photo dictionaries you retrieve from the photosInPlace:maxResults: method. You will need to use the new FlickrFetcher code available with this assignment. Use only the place’s name (as returned the the FLICKR_PHOTO_PLACE_NAME key) to determine what the place is (i.e. ignore things like the Flickr place id).

In both storyboards add two additional table view controllers with two new subclasses. Set their cell types and reuse identifiers. The first one will be used for the places in the itinerary, the second one for its photos. Create a push segue from the itinerary cell of the vacation view controller to the first new table view controller, another push segue from its cell to the second new table view controller and – only for the iPhone storyboard – an additional segue from the cell of the second new table view controller to the photo view controller from the previous assignments. Name all segue identifiers accordingly.

When the user chooses a Virtual Vacation from the list, bring up a static table view with two choices: Itinerary and Tag Search.

In both storyboards add an additional table view controller, create a subclass for it and set it up in story board. Create a push segue from the prototype cell of the vacations table view controller to the new table view controller.

The tricky part of this task is to make the table static. Select the table view of the table view controller and change its content type from previously Dynamic Prototypes to Static Cells. Label the first cell “Itinerary”, the second “Tag Search” and delete the third cell.

The sixth assignment continues the application from the last assignments which create a Flickr photo browser. This assignment will add features emphasizing the use of Core Data.

This application lets the user assemble a Virtual Vacation of places in the world to visit. Users will use the photo-choosing capabilities of your Fast Map Places application to choose photos in the places they want to go. In this application you will have two major tasks: allowing the user to choose where they want to go and allowing the user to “go on vacation” in their Virtual Vacation spots. You will accomplish the former by adding a “Visit/Unvisit” button to the scenes in your Fast Map Places where a photo is displayed. You will accomplish the latter by adding a new tab to your Tab Bar Controller which lets the user peruse their Virtual Vacation either by place or by searching for tags that were found in the Flickr dictionaries for the photos they chose to visit.

1. Add a new tab to your application that displays a new table view controller showing a list of all the “Virtual Vacations” found in the user’s Documents directory in their sandbox. A Virtual Vacation file is created by saving a UIManagedDocument (more on this below). Each vacation must have it’s own separate file in the Documents directory.
