Alert when new version of iOS app is available

Question

Is there an open source library out there for presenting an in-app alert when a new version is available to download? Push notification would be a plus also.

Answer 1

iVersion sounds like the exact thing you are looking for. It works similar to Sparkle on Mac OSX where it consults a remote file on your website where you can bump the version number once Apple approves your app and shows a prompt to the user if their version is lower than the one specified on your server.
