Store image in core data and Retina Display?

Question

I have an app that has hundreds of words with 3/4 images for each word. I have 2 versions of each word one for iOS 3 and one for retina display. I wish to save the images as data and connect them to the appropriate word so it will be easy to pull them later.

my question is - how do i get the suitable size ? its works great with the @2x wjen you get it from the app file system, but hoe does it supposed to work when i get it from data ?

thanks shani

Answer 1

Storing images in CoreData is a rather ill-advised idea. It will significantly bloat the size of the CoreData database and cause memory issues when you have faulted-in objects containing images. Instead you should write the images out to the filesystem and store the image path in CoreData.

Answer 2

It's not quite unusual that you save the images with Core Data. Take a look at the sample iPhoneCoreDataRecipes to see how Apple stores the images in Core Data as Transformable Type.
