This is a simple library to easily create a messaging app with smooth animations.
Things that can be customized:
• EVERYTHING!!!

Requirements

Xcode 5
iOS 7.0 +
ARC

Installation with CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries installation in your projects.

Podfile

pod "SOMessaging", "~> 1.0.0"

USAGE

Copy SOMessaging folder to your project.

Link MediaPlayer.framework, QuartzCore.framework.

Make a class that conforms to protocol SOMessage and synthesize all properties of that protocol. (In this demo it will be Message).

Make subclass of SOMessagingViewController

Override the following required methods of the SOMessagingDataSource protocol:

- (NSMutableArray *)messages
{
    //return array of id<SOMessage> objects
}

- (void)configureMessageCell:(SOMessageCell *)cell forMessageAtIndex:(NSInteger)index
{
    id<SOMessage> message = self.dataSource[index];
    
    // Customize balloon as you wish
    if (message.fromMe) {

    } else {

    }
}

Override the following (required) methods for the SOMessagingDelegate protocol:

- (void)didSelectMedia:(NSData *)media inMessageCell:(SOMessageCell *)cell
{
    // Show selected media in fullscreen
    [super didSelectMedia:media inMessageCell:cell];
}

- (void)messageInputView:(SOMessageInputView *)inputView didSendMessage:(NSString *)message
{
    if (![[message stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] length]) {
        return;
    }

    Message *msg = [[Message alloc] init];
    msg.text = message;
    msg.fromMe = YES;

    [self sendMessage:msg];
}

- (void)messageInputViewDidSelectMediaButton:(SOMessageInputView *)inputView
{
    // Take a photo/video or choose from gallery
}

You are done!

@optional

/**
 * Default implementation of this method for calculating the height of the cell for a message at given index.
 */
- (CGFloat)heightForMessageForIndex:(NSInteger)index;

/**
 * Messages will be grouped by a return time interval (in seconds).
 * return 0 if you don't want grouping.
