Re: Invalidating UIImageView's image cache

Yes! +[UIImage imageNamed:] was The Caching Culprit™️. I was barking up the wrong object (UIImageView). As per Eric's suggestion I've switch to +[UIImage imageWithContentsOfFile:], and now there's no image caching (as per Mike's suggestion to RTM: "This method does not cache the image object".

Invalidating UIImageView's image cache

Q: What is the proper way to invalidate UIImageView's image cache? - - - I have an iPad app that generates a series of medical analysis UIImages in the ~/Documents area of the sandbox. I then display those images in an automated sequence on the GUI. Each time the app runs through its processin
