# ChatMessageTableViewController A messages UI for iPhone. ChatMessageTableViewController is like iMessage app. support text && image . ![Messages Screenshot 1][img1] ![Messages Screenshot 2][img2] 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][link1] in the `Screenshots/` directory. (Surprise!)** ## About This is based on work by [@soffes](http://github.com/soffes) [SSMessagingViewController][ss].
