¿Incluyo en las esquinas redondeadas en mi diseño de iconos de aplicaciones para el iPhone?

Como otros han dicho, usted don't quiere redondear sus esquinas. Usted quiere enviar plana (sin capas o alfa) gráficos cuadrados. Apple cambió la máscara que utilizan para redondear sus esquinas en iOS7 y luego de nuevo en iOS8. Usted puede encontrar estas máscaras dentro de su paquete de aplicaciones Xcode. La ruta cambia con cada nueva versión del SDK que lanzan. Así que, te mostraré cómo puedes encontrarlo siempre.

  1. Busca /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs -name 'MobileIcons.framework' 

At this very moment, the path found by that command is /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/MobileIcons.framework but don't trust that. Use the command to find it yourself.

That path points to a directory with these files (again, at the time of this post)

As you can see, there are a lot of different masks, but they are named pretty clearly. Here is the AppIconMask@3x~iphone.png image:

main-qimg-fa13beb8faa5b5ad2b5534932f5c1f7f.webp

You can use that to test your icon to see if it will look okay after it is masked. But, don't round your corners. If you do, when Apple changes those masks again, you will have artifacts.
