Fresh Air is an application update library. It is designed check a remote location for application updates and if updates are available, prompt the user to upgrade the application. When the new version of the application is started, a dialog can be presented that show case the new features available to the user.

Fresh Air supports checking iTunes for a new version, or checking a remotely hosted release_notes.json file.

let upgradeManager = RZFUpgradeManager(appStoreID:"ANAPPID")
upgradeManager.checkForNewUpdate()

This will check the iTunes for an app with the specified ID, and present a dialog if an update exists. See RZFUpgradeManager for details on the UI presentation

Fresh Air also supports presenting release notes as a series of paging images with a title and description to introduce users to the new features included in an app update. This is managed by a set of feature keys specified in a release_notes.json file that is included in the application bundle. This file resides in a bundle that includes all of the assets needed for presentation. The feature keys are expanded into an image, a title, and a description via [UIImage imageNamed:$key], and the localization keys $key.title and $key.description. The usual asset lookup rules apply, so if different images are desired on iPhone vs iPad, use the ~iphone and ~ipad suffix. If localized images are desired, make sure that the images are only placed in the .lproj directories, and not in the top level directory.

Fresh Air comes with english localization for the update prompt. This can be customized by adding the localized keys from FreshAirUpdate.strings to your application's main bundle's Localizable.strings file. To configure an image, add an image named freshair_update to the bundle.

The release_notes.json file describes the version history of the application. Every release entry contains any number of 'feature' keys to denote marketing features. There is an Example of the release note file and a JSON Schema file that can be used to validate your releases_notes.json file.
