问题
In iOS's Mail app, when you enter in the email of someone who is in your contact list it formats the text in an interactive bubble. I can't seem to find any obvious way to do this, and it's exactly what my app needs to do, and I'm not even sure where to start.
Any pointers to where to look would be appreciated!

Looks like a duplicate of Is there an iPhone equivalent to the NSTokenField control?
Short answer, no, nothing public. But there are 3rd party implementations, like TTPickerTextField class in http://joehewitt.com/post/the-three20-project/.
