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 38-1
must meet specific criteria so that iOS can display them properly.
In
addition, some icon and image files have naming requirements. (If you
need to support standard-resolution iPhone or iPod touch devices, divide
by 2 the high-resolution sizes listed below.)

each for red, green, and blue—plus an 8-bit alpha channel.
