CountryPicker is a custom UIPickerView subclass that provides an iOS control allowing a user to select a country from a list. It can optionally display a flag next to each country name, and the library includes a set of 249 high-quality, public domain flag images from FAMFAMFAM (http://www.famfamfam.com/lab/icons/flags/) that have been painstakingly re-named by country code to work with the library.

JPNG is a bespoke image file format that combines the compression benefits of JPEG with the alpha channel support of a PNG file. The JPNG library provides an Objective-C implementation of this format along with transparent JPNG loading support for iOS and Mac OS.

StandardPaths is a category on NSFileManager for simplifying access to standard application directories on iOS and Mac OS and abstracting the iCloud backup flags on iOS. It also provides support for working with device-specific file suffixes, such as the @2x suffix for Retina displays, or the -568h suffix for iPhone 5 and can optionally swizzle certain UIKit methods to support these suffixes more consistently.

ViewUtils is a collection of category methods designed that extend UIView with all the handy little properties and functionality that you always wished were built-in to begin with.

Simple, drop-in replacement for the iPhone UIPageControl that allows customisation of the dot colour, size and spacing.

BaseModel provides a base class for building model objects for your iOS or Mac OS projects. It saves you the hassle of writing boilerplate code, and encourages good practices by reducing the incentive to cut corners in your model implementation.
