Dev:IconSupport

IconSupport is a library that helps icon-layout-modifying tweaks play nicely together.

Quoted from its depiction:

IconSupport is a package for use by extensions that modify how SpringBoard lays-out icons (such as extensions that change the number of icons shown per row/column). Normally, syncing with iTunes or booting into Mobile Substrate's Safe Mode would cause these modified layouts to be reset; IconSupport prevents this. IconSupport also handles repairing layouts when installing and uninstalling IconSupport-enabled extensions.

Quoted from the README of its source on GitHub:

Uses a unique ID for each combination of packages, so icon state is never lost via respring or uninstalling a new package.

Example usage (in the initializer function of your extension): dlopen("/Library/MobileSubstrate/DynamicLibraries/IconSupport.dylib", RTLD_NOW); [[objc_getClass("ISIconSupport") sharedInstance] addExtension:@"theNameOfMyExtension"];
