Automatic Update of IPhone App

I am new to iPhone automatic updatability feature where user can change their contents whenever they want and iPhone app should pick them so that one need not to resubmit the application into Apple store. I know that I will need to deal with the database here a lot but if someone could through their idea on the solution design, implementation, and things to be taken care then that would be really helpful to me.

Thanks.

Apple not only allows this, but presented a session on this data driven app design technique at WWDC 2010, which is available as a video from iTunes to enrolled iOS developers.

Of course, the downloaded "content" can't include executable code, but it can include JavaScript and HTML5 to be run inside UIWebViews, as well as images, sounds, text, databases, etc., which can all be stored for offline use.

It should be mentioned that web apps offer the ultimate in automatic content updates. You can change the content, structure, and features of a web app without ever having to submit your app to Apple or anyone else. Deploying the app is as simple as copying a set of files to your server, and users get the updated version immediately, even if they're currently using the app. Web apps aren't a perfect solution in every case, but their capabilites are compelling if your app is dynamic.

"content" here really means data. Apps can load data over the net to their hearts' content, but they can't load new code. Now, certain data might cause the existing code in the app to do one thing or another, so the app's behavior can be influenced by the data it uses. Don't play too close to the line, though -- if your data is really some form of scripting language that directly drives the behavior of the app, that will likely be deemed unacceptable.

As far as loading the content goes, there are a number of options available. The most common is probably using NSURLConnection asynchronously to load data from a web server. What the app does with the data after that is up to the app designer, and I don't think there's one objectively correct answer to that sort of question.

This violates apples SDK Agreement and will likely get your app removed from the app store if caught.
