JSMessagesViewController

A messages UI for iPhone and iPad.

JSMessagesViewController is a UIViewController subclass that is very similar to the iOS Messages app.

Note: this is only a messaging UI, not a messaging app.

See more screenshots in the Screenshots/ directory.

Requirements

iOS 6.0+
ARC
JSQSystemSoundPlayer

Installation

From CocoaPods

pod 'JSMessagesViewController'

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

Subclass JSMessagesViewController
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";
}

Implement the JSMessagesViewDelegate protocol
Implement the JSMessagesViewDataSource protocol
Implement - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section from the UITableViewDataSource protocol.
Present your subclassed ViewController programatically or via StoryBoards. Your subclass should be the rootViewController of a UINavigationController.
Be a badass programming-motherfucker and read the fucking documentation. (Yes, there's documentation! Seriously!)
See the included demo: JSMessagesDemo.xcworkspace
- Don't forget to run pod install before opening the demo!

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

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 want to do — I know, this is shocking. 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.
