Stack Overflow Answer 2

This is an answer to Stack Overflow question here where the questioner was asking how to update a cell in a UITableView. This demo shows how to connect data to UI using ALTableViewHelper available on , and so remove the need for any code to copy the data when it updates.

The main 'engine' is this section:

tableView.setHelperString("""
section
    headertext "Conversation Status"
    body
        Conversation
            $.viewWithTag(1).text <~ conversations[conversations.count-1]["title"]
            $.viewWithTag(2).text <~ "At \\(dateFormat.stringFromDate(conversations[conversations.count-1]["update"]))"
        UpdateButton
            $.viewWithTag(1).isAnimating <~ FakeConversationGetter.singleton.busy
""", context: self)

where the data is connected with the UI. Filling and updating the UITableView is fully handled once the connections are described.

$ is the view added, and <~ is the 'connect this to that' operator.

What isn't shown in this example is that sections and section views can be 'multiplied' by the contents of arrays - one section or view for each array member.
