Devo includere gli angoli arrotondati nel design dell’icona della mia app per iPhone?



di

Come altri hanno detto, non vuoi arrotondare gli angoli. Vuoi spedire una grafica quadrata piatta (senza livelli o alfa). Apple ha cambiato la maschera che usano per arrotondare gli angoli in iOS7 e poi di nuovo in iOS8. Potete trovare queste maschere all'interno del vostro bundle di applicazioni Xcode. Il percorso cambia con ogni nuova versione SDK che rilasciano. Quindi, vi mostrerò come potete sempre trovarlo.

  1. find /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.
