TTPickerTextField example

I've been trying all day and just can't make the the TTPickerTextField work. It displays, I set its dataSource to the example code's MockDataSource and type in a name from the mock and it doesn't work. There doesn't seem to be any documentation or any examples anywhere on the internet, something that I find surprising.

So: does anyone have (or can anyone th开发者_如何转开发row together) a really simple example of how the TTPickerTextField works? All I want to do is have someone type something in and put it in a bubble, like in the iPhone Mail app.

Have you seen this example?
