Read the blog post about the 6.0 release!

Demo Project
- There's a sweet demo project: JSQMessages.xcworkspace.
- Run pod install first.
- Firebase also has a sweet demo project, and it's in Swift!
Message Model
- Your message model objects should conform to the JSQMessageData protocol.
- However, you may use the provided JSQMessage class.
Media Attachment Model
- Your media attachment model objects should conform to the JSQMessageMediaData protocol.
- However, you may use the provided classes: JSQPhotoMediaItem, JSQLocationMediaItem, JSQVideoMediaItem.
- Creating your own custom media items is easy! Simply follow the pattern used by the built-in media types.
- Also see JSQMessagesMediaViewBubbleImageMasker for masking your custom media views as message bubbles.
Avatar Model
- Your avatar model objects should conform to the JSQMessageAvatarImageDataSource protocol.
- However, you may use the provided JSQMessagesAvatarImage class.
- Also see JSQMessagesAvatarImageFactory for easily generating custom avatars.
Message Bubble Model
- Your message bubble model objects should conform to the JSQMessageBubbleImageDataSource protocol.
- However, you may use the provided JSQMessagesBubbleImage class.
- Also see JSQMessagesBubbleImageFactory and UIImage+JSQMessages.h for easily generating custom bubbles.
View Controller
- Subclass JSQMessagesViewController.
- Implement the required methods in the JSQMessagesCollectionViewDataSource protocol.
- Implement the required methods in the JSQMessagesCollectionViewDelegateFlowLayout protocol.
- Set your senderId and senderDisplayName. These properties correspond to the methods found in JSQMessageData and determine which messages are incoming or outgoing.
Customizing
- The demo project is well-commented. Please use this as a guide.

Quick Tips

Springy bubbles?

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    self.collectionView.collectionViewLayout.springinessEnabled = YES;
}

Remove avatars?

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.collectionView.collectionViewLayout.incomingAvatarViewSize = CGSizeZero;
    self.collectionView.collectionViewLayout.outgoingAvatarViewSize = CGSizeZero;
}

- (id<JSQMessageAvatarImageDataSource>)collectionView:(JSQMessagesCollectionView *)collectionView avatarImageDataForItemAtIndexPath:(NSIndexPath *)indexPath
{
    return nil;
}

Customize your cells?

- (UICollectionViewCell *)collectionView:(JSQMessagesCollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
    JSQMessagesCollectionViewCell *cell = (JSQMessagesCollectionViewCell *)[super collectionView:collectionView cellForItemAtIndexPath:indexPath];
    
    // Customize the shit out of this cell
    // See the docs for JSQMessagesCollectionViewCell
    
    return cell;
}

Customize your toolbar buttons?

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    // This button will call the `didPressAccessoryButton:` selector on your JSQMessagesViewController subclass
    self.inputToolbar.contentView.leftBarButtonItem = /* custom button or nil to remove */
    
    // This button will call the `didPressSendButton:` selector on your JSQMessagesViewController subclass
    self.inputToolbar.contentView.rightBarButtonItem = /* custom button or nil to remove */
    
    // Swap buttons, move send button to the LEFT side and the attachment button to the RIGHT
    // For RTL language support
    self.inputToolbar.contentView.leftBarButtonItem = [JSQMessagesToolbarButtonFactory defaultSendButtonItem];
    self.inputToolbar.contentView.rightBarButtonItem = [JSQMessagesToolbarButtonFactory defaultAccessoryButtonItem];
    
    // The library will call the correct selector for each button, based on this value
    self.inputToolbar.sendButtonOnRight = NO;
}

About

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

As it turns out, messaging is something that iOS devs and users really want. Messaging of any kind has turned out to be an increasingly popular mobile app feature in all sorts of contexts and for all sorts of reasons. Thus, I am supporting this project in my free time and have added features way beyond what Hemoglobe ever needed.

Feel free to read my blog and check out my work at Hexed Bits.
