Download additioanal functionality into an app - is it possible?
<p>I'm currently developing an iPhone version of existing Android application.
Customer wants to provide his web services via mobile apps. On Android this is made in a modular way: user installs main app, and then he can download additional modules to it if needed. That way he can install only modules that he needs.
Is there a way to achieve same functionality on iPhone? I read about In-App Purchasing, but I don't know if it will work because additional functionality will not be built-in and unlocked - it needs to be downloaded and added to my app as a new module - so user's space would not be wasted with unneeded modules.</p>

<p>Thank you!</p>
