I have an iPhone Xcode project that currently only contains images for retina display (twice the size as normal and with a @2x.png suffix). When I run the app on the iPhone Simulator (non retina) the images are still being displayed. Does this mean I don’t need to worry about including two sets of images: retina and non-retina?
This all seems a bit odd. I would assume that no images would appear on a non retina device if there are no non-@2x files included.
Note: I have not tested my app on a non retina device. Just the simulator.
Even if it works, it’s not good practice, and if you have a media heavy app definitely it would impact performance and battery life and memory foot print and ….
