UIBubbleTableView is UITableView based iOS component for rendering chats like it's done in Messages application. Now comes with "typing" bubble and images in the chat.

If you're sick and tired of the old UIActionSheet and UIAlertView's look or just can't do what you want with them, these classes are the answer to your prayers. The classes can be easily customized to your look and feel and they're even easier to use than the iOS API classes because they use blocks for the actions, not a freaking delegate.

This is a container controller for presenting side views like Path or Facebook application. It is really simple to use, like UINavigationController, works on both iPhone and iPad, really easy to setup and lot of options are available. I created this component from scratch, because the others I saw weren't so easy to integrate in a app. There is a documentation up to date, and two sample code provided. One shows how to easily integrate PPRevealSideViewController in an app, and the other shows lot of options and all the configurations available. A youtube video is also available to see the component in action.
