• Universal for iPhone and iPad

Requirements

• iOS 6.0+
• ARC
• JSQSystemSoundPlayer

Installation

From source

• Drag the JSMessagesViewController/ folder to your project
• Download JSQSystemSoundPlayer and follow its install instructions
• Add the QuartzCore.framework to your project

Too cool for ARC?

• Add the -fobjc-arc compiler flag to all source files in your project in Target Settings > Build Phases > Compile Sources.

Getting Started

Setup your model

Your model objects should conform to the JSMessageData protocol. However, you may use the provided JSMessage class for your model objects if you wish.

Setup your view controller

1. Subclass JSMessagesViewController
2. Conform to the protocols <JSMessagesViewDelegate, JSMessagesViewDataSource>
3. Implement the JSMessagesViewDelegate protocol
4. Implement the JSMessagesViewDataSource protocol
5. Implement tableView: numberOfRowsInSection: from the UITableViewDataSource protocol.
6. Setup your viewDidLoad like the following:

- (void)viewDidLoad
{
    self.delegate = self;
    self.dataSource = self;
    [super viewDidLoad];

    [[JSBubbleView appearance] setFont:/* your font for the message bubbles */];

    self.title = @"Your view controller title";

    self.messageInputView.textView.placeHolder = @"Your placeholder text";

    self.sender = @"Username of sender";
}

Present your view controller

1. Present your subclassed view controller programatically or via StoryBoards. Your subclass should be the rootViewController of a UINavigationController, or pushed on an existing navigation stack.

2. You may want to show the most recent message when presenting your view: (this is no longer default behavior)

// Scroll to the most recent message before view appears
- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self scrollToBottomAnimated:NO];
}

Questions?

1. Be a badass programming-motherfucker and read the fucking documentation. Yes, there's fucking documentation! And it is fucking kept up-to-date. How fucking sweet is that? Pretty fucking sweet.
2. See the included demo: JSMessagesDemo.xcworkspace. Don't forget to run pod install before opening!
3. Still need help? That's ok! Just open a new issue with your question, and add the question label.
4. Please do not email me your question if you need help. But I really want to email you. Why can't I?
   • Opening an issue is better for you and the community, because it provides better transparency.
   • I'm often busy and may not reply in a timely manor.
   • People using this library and watching this repo may be able to answer your question sooner.
   • Someone else likely has a similar question and also needs an answer.
   • Users of this library can search the issues for previously asked questions.

Customization

• You can customize almost any property of a cell by implementing the optional delegate method configureCell: atIndexPath:

- (void)configureCell:(JSBubbleMessageCell *)cell atIndexPath:(NSIndexPath *)indexPath
{
    if ([cell messageType] == JSBubbleMessageTypeOutgoing) {

        // Customize any UITextView properties
        cell.bubbleView.textView.textColor = [UIColor whiteColor];

        if ([cell.bubbleView.textView respondsToSelector:@selector(linkTextAttributes)]) {
            NSMutableDictionary *attrs = [cell.bubbleView.textView.linkTextAttributes mutableCopy];
            [attrs setValue:[UIColor blueColor] forKey:UITextAttributeTextColor];

            cell.bubbleView.textView.linkTextAttributes = attrs;
        }
    }

    // Customize any UILabel properties for timestamps or subtitles
    if (cell.timestampLabel) {
        cell.timestampLabel.textColor = [UIColor lightGrayColor];
        cell.timestampLabel.shadowOffset = CGSizeZero;
    }

    if (cell.subtitleLabel) {
        cell.subtitleLabel.textColor = [UIColor lightGrayColor];
    }

    // Enable data detectors
    cell.bubbleView.textView.dataDetectorTypes = UIDataDetectorTypeAll;
}

• Set the font for your messages bubbles via UIAppearance

[[JSBubbleView appearance] setFont:[UIFont systemFontOfSize:16.0f]];

• Customize your message bubbles with JSBubbleImageViewFactory

• Customize your avatars with JSAvatarImageFactory

About

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

As it turns out, messaging is a popular thing that iOS devs and users want. Thus, I am supporting this project in my free time and have added features way beyond what Hemoglobe ever needed.

Check out my work at Hexed Bits.
