Auto-updated iOS application for enterprise distribution

Question

Is it possible to make an iOS application for enterprise distribution that updates itself transparently? Saying 'updates' I mean completely updating its logic.

A possible usage of this approach is a self-service kiosk (iPad) that is maintained remotelly.

It's not possible to update application binaries directly, but I see some possibilities:

1. Application that have a single UIWebView and the logic is implemented in HTML5. But we can't use most of hardware specific features that can be used in native applications.
2. Some multi-platform framework (possibly HTML5-based) that allows to use native application features and that is compiled or interpreted dynamically.
3. Jailbreak?

What are really working approaches of these?

Answer 1

Consider getting a mobile device management service. Those are pricey.

OR:

First, enable over-the-air distribution. It will take $300/year enterprise agreement with Apple. Set up a website with the app's IPA archive and descriptive PLIST.

Then code a call-home HTTP request on app startup. You may pull/parse the same PLIST that describes the latest version; it has a bundle version in it. Compare that to the version of the currently running bundle.

When a new version is detected, the app shuts down, opens the browser on the download page. In a softer manner, just notifies the user that an upgrade is available.

I've never tried linking directly to the app's download package, but give it a try. In a perfect world, Safari would open up and ask "Do you want do download MyApp?" right away. In a not so perfect world, the user would have to click a link and then agree to download.
