Join Bill Weinman for an in-depth discussion in this video Updating the item view with the feed items, part of iOS App Development: Building Data-Driven Apps with SQLite.
- At this point, we've loaded the RSS feed…using NSURLConnection…and we parsed it with NSXMLParser.…Now we're ready to display the feed…in the table view controller.…Here I've opened a working copy of BWRSS…items 03 from chapter four…of the Exercise files.…Now that the data is loaded in the database,…displaying it is not much different…than any other table view.…The first thing you'll see here in this class…is this view will appear and so this actually gets called…before the view appears and so I do a couple of things.…
I set the row height for the table view…and here I delete the old items from the feed…and that's calling delete old items in RSSDB…and if we look here, we get item methods,…deleteOldItems.…Go ahead and close the left bar here so we can see this.…So this uses a pretty clever little piece of SQL.…It uses an SQL sub select to order the items…by publication date descending,…so the first items are the newest ones,…and then it uses the limit clause to limit…that to the number that we're allowed to keep…
