iphone: creating the 'blue bubble contacts' effect in ComposeEmail?

Question

Hi, I want to create an effect similar to the 'blue bubble tag' effect in the Compose Email Page where the recipients email address appears.

I need to design a similar effect to allow users to create 'tags' for a picture.. Do I have to use Core Animation for this? Can someone please give me some pointers on where / what i need to use?

Three20 has something that is like this. You can mine it for code. What you are looking for is in the TTMessageController
