Apple's Asking Its Developers for iOS 7 Compatible Icons
According to 9to5Mac, Apple is currently asking developers to include iOS 7 compatible icons to the apps they submit for the company’s approval. This is all because of the specific size and shape of the icons for iOS 7 - they’re a bit larger and have a different corner radius.
Here’re some lines from the Apple’s note to developers:
In order to avoid this interface issue, developers will need to include larger icons in their applications. iOS 6 icons on the iPhone come in at 114 x 114 pixel resolutions, while iOS 7 icons are slightly larger at 120 x 120 pixel resolutions. For the iPad, iOS 6 icons are at resolutions of 144 x 144, and on iOS 7 they come in at a resolution of 152 x 152.
You’ll be able to take a look at those bigger icons and other improvements brought by the new iOS version this September after the official iOS 7 release.
