title: Huge image I want to manipulate in my Xcode app
body: <p>I have a huge map image (25mb) that I want to use in my app. The entire point of the app is to pinch zoom and scroll around this richly detailed map.</p>
  
  <p>I am loading it in a uiimageview, with some subview layers that can be toggled on and off to overlay the map.</p>
  
  <p>Everything is working fine code wise and on my simulator, but my concern is that the actual iPhone/iPad may have problems rendering/manipulating a 25mb png image.</p>
  
  <p>Anyone have experience with huge image files in Xcode? Any recommendations or concerns about what I have described? </p>
  
  <p>Someone suggested using uiwebview to display the image. I'm not sure why thy would be any better.</p>
  
  <p>Thanks</p>
