iCarousel
iCarousel is a class designed to simplify the implementation of various types of carousels (paged, scrolling views) on iPhone and iPad. iCarousel implements a number of common effects such as cylindrical, flat and "CoverFlow" style carousels, as well as providing hooks to implement your own bespoke effects. Unlike many other "CoverFlow" libraries, iCarousel can work with any kind of view, not just images, so it is ideal for presenting paged data in a fluid and impressive way in your app. It also makes it extremely easy to swap between different carousel effects with minimal code changes.
MBProgressHUD
An easy to use progress indicator for iOS that includes both fixed and indeterminate styles.
JASidePanels
UIViewController container designed for presenting a center panel with revealable side panels - one to the left and one to the right.
PDF Reader Core
Open source PDF reader code for fellow iOS developers struggling with wrangling PDF files onto iOS device screens. The code is universal and does not require any XIBs (as all UI elements are code generated, allowing for greatest flexibility). It runs on iPad, iPhone and iPod touch with iOS 4 and up. This implementation has been tested with large PDF files (over 250MB in size and over 2800 pages in length) and with PDF files of all flavors (from text only documents to graphics heavy magazines). It also works on older devices (such as the iPod touch 2nd generation and iPhone 3G) and takes advantage of the dual-core processor (via CATiledLayer and multi-threading) in all new devices.
DAKeyboardControl
DAKeyboardControl allows you to easily add keyboard awareness and scrolling dismissal (a receding keyboard ala iMessages app) to any UIView, UIScrollView or UITableView with only 1 line of code. DAKeyboardControl automatically extends UIView and provides a block callback with the keyboard's current origin.
