So try to do what Apple and I suggested with this answer. With the upcoming release of iOS 7 you will notice that the 'standard' icon radius has been increased. In most situations it would probably be hard to tell the difference between a transparent 512px icon masked at a 90px radius and one masked at 89.825, but the antialiasing of the rounded corner would definitely end up slightly different and would likely be visible in certain circumstances especially if a second, more precise mask is applied by Apple, in code, or otherwise. Not sure what's going on there, but it's definitely using and storing the more precise number that was entered.Īnyhow, I've updated the list above to include just 3 digits after the decimal point (before there were 13!). And several times the Round Rectangle Tool didn't round up and actually showed multiple digits after the decimal point. The Round Rect Tool sometimes rounds the input to the nearest whole number, but you can see a significant difference between 90 and 89.825. I did some tests in Photoshop CS6 and it seems as though 3 digits after the decimal point is enough precision to end up with the exact same vector (at least as displayed by Photoshop at 3200% zoom).

Knowing the above is important, however, for icon usage within app UI where you have to apply the mask in code, or pre-rendered in photoshop. Apple will automatically mask each icon in the appropriate context. Those should all be square and not have any transparency. Here is a list of the most commonly used icons, proper naming conventions, pixel dimensions, and corner radii.Īlso, as mentioned in other answers, you don't actually want to crop any of the images you use in the binary or submit to Apple. Thus you can calculate the radius for any icon size using 10/57 x new size (for example 10/57 x 114 gives 20, which is the proper radius for a 114px icon). Apple starts with the 57px icon and a radius of 10 then scales up or down from there. Use launch.png at 320x480 and at 640x960.Īfter trying some of the answers in this post, I consulted with Louie Mantia (former Apple, Square, and Iconfactory designer) and all the answers so far on this post are wrong (or at least incomplete). You can see this in action on the Summary page of the application target if you've done it right. To add a retina-compatible file, use the same file name and add So if I had a file for my 72x72 icon named icon.png, I would also add a 114x114 PNG file named to the project/target and Xcode would automatically use that as the icon on a retina display. There is also a very good answer from which has the location of image mask files used in the SDK for rounding icon corners If you do create a set of custom icons, you can set the UIPrerenderedIcon option to true in your ist file and it will not add the gloss effect but it will place a black background under it and still round the image corners with these corner radii so if the corner radius on any of the icons is greater then it will show black around the edges/corners.Įdit: See comment from and you can see that any future icon sizes should have a 1:6.4 ratio of corner radius to icon size. corner radius for the 144x144 icon = 23 (iPad Retina).corner radius for the 72x72 icon = 11 (iPad).corner radius for the 114x114 icon = 18 (iPhone/iPod Touch Retina).

corner radius for the 57x57 icon = 9 (iPhone/iPod Touch).corner radius for the 1024x1024 icon = 180 (iTunesArtwork Retina).corner radius for the 512x512 icon = 80 (iTunesArtwork).You can make four icons (as of today) for your app and they can all have a different look - not necessarily based on the 512x512 image.
