title: Local storage for iPhone app
body: <p>I want to develop an application. The functionality is similar to RSS feed reader. Read a XML from web service and display them in a table view. But I have some problems to deal with the local storage. I do not need to store all the history records since it takes a lot of storage. But I do want to store dozens of newest records so the user can really see something even when the new data is loading or there is no network connection. What should I do? Should I use Coredata or other methods?</p>
