iOS : how can I check programmatically if the app is up to date?

Question

I want to check if my app is up to date, and if not suggest to download the latest one.

I went through this topic and found some ideas, but I still don't know how to check the latest version.

I also would like to know how I can display this information only one time and not every time the user launches the app or the main view appears.

Thanks for your help.
