I\'m probably missing something obvious here, yet I\'ve been unable to solve the following problem:
I have a project with image resources for both normal and retina
Have you tried to simply load the image using:
UIImage * someImage = [UIImage imageNamed: @"someimage"];
(assuming your have an image named 'someimage' in you project, for example someimage.png)
The code will automatically pick retina/non-retina versions depending on the platform.
If the problem is that the TIFF are created, check:
In latest version of XCode, go to the Editor menu, then select "validate settings", which should remove that artwork combination.
