MessagesTableViewController

A messages UI for iPhone and iPad.

   

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!)

About

This is based on work by @soffes SSMessagingViewController.

I developed this to use in Hemoglobe for private messages between users.

Square message bubbles designed by @michaelschultz.

Installation

From CocoaPods

From source

• Drag the JSMessagesTableViewController/ folder to your project.

The method scrollToRowAtIndexPath:indexPath:atScrollPosition:animated: can also be used to implement scrolling functionality that respects this setting.
  • Set your view controller title

#####Implement the JSMessagesViewDelegate protocol

- (void)sendPressed:(UIButton *)sender withText:(NSString *)text

• Hook into your own backend here
• Call [self finishSend] at the end of this method to animate and reset the text input view
• Optionally play sound effects
  • For outgoing messages [JSMessageSoundEffect playMessageSentSound]
