I have a simple question. Lets say I have an about screen, where I show a company logo or app logo.
64x64logo.png
128x128logo@2x.png
about screen is loaded with logo.png
how do we swap high resolution image for retina based iphones
or will the system do it by itself.
Your retina device will take care of it, only you need to add 2 images in resources, one for non-ratina UI and another for ratina UI.
The only thing you need to take care is to give same name to the both the images and add @2x postfix to ratina image.
like this:
