Version 1.1.0 of Gagat adds support for Objective-C clients (i.e. using Gagat from apps written in Objective-C)! See the README for instructions on how to use Gagat from Objective-C.

There's also two new (optional) methods in GagatStyleable: styleTransitionWillBegin() and styleTransitionDidEnd() which allow you to do things right before a Gagat transition begins or right after it ends. Thanks to @iKenndac for contributing these methods!
