How to detect whether there's a newer version of my iOS application? [duplicate]

Question

I would like to provide an alert within my iOS app if there is a new version available from iTunes. I can't find an API for this. Is this possible?

Answer 1

There's a good argument that you don't need to do anything. The App Store app will already notify users when updates are available.

However, if you want to do it anyway, there's a project on GitHub called iVersion that does most of the heavy lifting for you. (Not tried it myself, but it looks pretty good.)
