Kinda like an NSTokenField for iOS (see Messages / Mail apps).

Usage

See the "TokenFieldExample" app for details on usage. It's limited at the moment to one tokenising field and a content view below because it's pulled straight from one of my apps. Multiple field support requires tweaking.

ARC?

Yup
