If a user touches an entry for a hashtag or a user in the “mentions table view” that you created in Required Task 2 above, you should segue to show the results of searching Twitter for that hashtag or user. It should be searching for hashtags or users, not just searching for a string that is the name of the hashtag or user (e.g. search for “#stanford”, not “stanford”). The view controller to which you segue must work identically to your main Tweet-viewing view controller (TweetTableViewController).

Create a segue from the keyword cell to the initial table view controller (and name its identifier):

If a section has no items in it, there should be no header visible for that section.

… oops, didn’t notice that. We need to check if there are items to show:

    var tweet: Tweet? {
        ...
                if media.count > 0 { ... }
            ...
                if urls.count > 0 { ... }
            ...
                if hashtags.count > 0 { ... }
            ...
                if users.count > 0 { ... }
            ...
    }

The complete code for task #4 is available on GitHub.

Each section in the mentions table view should have an appropriate header.

We store already the title in our data structure, now just use it:

    override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        return mentions[section].title
    }

The complete code for task #3 is available on GitHub.

When a user clicks on a Tweet, segue to a new UITableViewController which has four sections showing the “mentions” in the Tweet: Images, URLs, Hashtags and Users. The first section displays (one per row) any images attached to the Tweet (found in the media variable in the Tweet class). The last three show the items described in Required Task 1 (again, one per row).

Add a new table view controller to story board and a new table-view-controller class which you link to the new controller. Add a segue from the tweet cell too the new controller (don’t forget to add a segue identifier).

Enhance Smashtag from lecture to highlight (in a different color for each) hashtags, urls and user screen names mentioned in the text of a Tweet (these are known as “mentions”). Note that mentions are already located for you in each Tweet by Twitter and show up as [IndexedKeyword]s in the Tweet class in the supplied Twitter code.

The tweet class provides nearly everything needed – arrays of indexed keywords. What’s left is to choose a color for the keyword type – as public properties of the cell view:

    var hashtagColor = UIColor.blueColor()
    var urlColor = UIColor.redColor()
    var userMentionsColor = UIColor.greenColor()
