A set of simple iOS and OS X applications that demonstrates how to use iCloud key-value store to share a single piece of data, its background color, with the same app on other iOS devices. It uses NSUbiquitousKeyValueStore to achieve this by storing a simple NSInteger representing a chosen color index. The user changes the background color of the app by choosing between 4 known colors.
