Re-Installing IPhone App From Inside The App

Question

I want to find a way if it's possible to re-install an IPhone app from inside it?

Let's say my users have the app already installed in their phones and now new version is released, can I make my app such that it will check over internet if new version is available and if it is, download it and ask the user to install it. If user says yes, it will first un-install the current version and will install downloaded version.

Is it possible anyhow?

Answer 1

Apple wont allow this.

• For one reason, un-installing the app removes all the user documents (if applicable), so theres no way to preserve user data.

• Apple already has a medium for updating (iTunes App Store).

If you want to be able to check if there is a newer version of your app, you can do that simply by checking a text file (for example) on your server, and notifying (by UIAlertView possibly) the user that there is a newer version of your app. But again, Apple already has a standard system in place.

Answer 2

probably not because to uninstall an app it requires the app to be closed
