title: Received memory warning
body: <p>I am working on an app with xml parser, uiwebview, navigationcontroller, displaying a lot of images on the main controller, that remains in the memory throughout the whole life of the app. I store my data using core data.<br />
  I tried to figure out the memory footprint of the application since I am getting the following warnings:</p>
  <blockquote>
  <p>Received memory warning. Level=1   app delegate received memory
  warning   main controller received memory warning   main controller
  received memory warning   RSSItem received memory warning</p>
  <p>Received memory warning. Level=2   app delegate received memory
  warning   main controller received memory warning   main controller
  received memory warning   RSSItem received memory warning</p>
  </blockquote>
  <p>The footprint is around 4MB, and jumps up to around to maybe 10 when I drill down and display UIWebViews with a significant number of images.
  Is that footprint too large? I assume that there are apps out that are considerably more complicated. From what I understand the apps have 40-70MB available, give or take, but definitely not 10MB limit. Anyone has any insight what can I do to fix it or work around the problem. I do not have leaks.
  I am afraid that the real problem is not the footprint but something else I am not aware of.
  Thanks for any help.</p>
