Retina devices require developers to create 2 types of images, an @2x resolution for retina displays and normal resolution for regular displays. Well, Apple may be adding a 3X resolution display to iOS 8. Marck Gunman reported that Apple was testing a 1704x960px resolution display for the iPhone 6, which would be achieved by tripling each pixel from the “base resolution”.
According to an iOS developer, James Thomson, a newly discovered bug in iOS 8 loads 3x images instead of 2x images. Is this an accident or is this intentional?
This means that in the future we may have to add another image size to our export list. We’ll have to export all of our asset images at normal resolution, 2x resolution, and 3x resolution. All I can say is I’m hoping this is just a fluke. The less work I have to do to make my images look nice on any device means more time to focus on other things.
It’s still to be determined whether we’ll have to export images at 3x resolution in the future, but if this is the case you’ll want to make sure to get started sooner than later. Be sure to checkout Apples next key note, scheduled for September 9th for the unveiling of iOS 8.
