Retina/non-retina images in UIImageView
I have a 300 x 300 sized UIImageView in my app which is displaying my images very nicely. My images are all 600 x 600 or larger and UIImageView simply resizes them for me. My question is this: as these images are essentially all retina images anyway (i.e. double the required pixel size) is there any point in making a retina and a non-retina version of the same image? Won't this just make my app bigger because of the extra image files? What's wrong with just letting the device downscale the images? I'm sure there's a very good answer so I'd like to know what it is! Thanks for your advice. For
