How do I round corners of myapp's icon

Question

In simulator mode, my app has an icon with round corners, but on a real iPhone, the corners aren't rounded.

Answer 1

Corners get automatically rounded if you install via MobileInstallation (from iTunes, Xcode or App Store). If you're building the package and installing it into /Applications manually or with cydia/apt, you have to make a rounded icon yourself.

You can find the images used to round the corners and add reflection in /System/Library/Frameworks/UIKit.framework/Other.artwork, the first 3 images are the mask, reflection and shadow. You can extract the .artwork file with this script here

Answer 2

by default the iPhone should round your corners and add a reflection effect. Be sure you have not added the UIPrerenderedIcon key to your Info.plist file. Hope this helps!
