Icon and Image Sizes

Every app needs an app icon and a launch image. In addition, some apps need custom icons to represent app-specific content, functions, or modes in navigation bars, toolbars, and tab bars.

Unlike other custom artwork in your app, the icons and images listed in Table 39-1 must meet specific criteria so that iOS can display them properly. In addition, some icon and image files have naming requirements (to learn about naming these files, see “App Icons” in iOS App Programming Guide and “App Launch (Default) Images” in iOS App Programming Guide).

For all images and icons, the PNG format is recommended. You should avoid using interlaced PNGs.

The standard bit depth for icons and images is 24 bits—that is, 8 bits each for red, green, and blue—plus an 8-bit alpha channel.

You don’t need to constrain your palette to web-safe colors.
