A messages UI for iPhone and iPad.

Messages Screenshot 1     Messages Screenshot 2

This messages tableview controller is very similar to the one in the iOS Messages app. Note, this is only a messaging UI, not a messaging app. This is intended to be used in an existing app where you have (or are developing) a messaging system and need a user interface for it.

See more screenshots in the Screenshots/ directory. (Surprise!)
