Create a popup "a new version of this app is available"

Question

Hi, I would like to display a popup in my iPhone app that alert users when a new version is available in the appstore with a direct link to the iTunes page of the app.

Do you know how can I implement that?

Thank you for your help.

Answer 1

Store the version in the app in a file or something. Then, store the latest version number on a server somewhere. When the app launches, see if they match.
