SpringBoardServices.framework is a C (and partially Objective-C) library that allows you to invoke functions in SpringBoard via IPC (Mach messages via MIG subsystem).

SpringBoardServices is a framework that is constantly changing. Almost every firmware has something different. Make sure you check the version if you use any function here.

SB functions

SB functions are the low-level functions that directly communicate with SpringBoard via MIG subsystem. See

SBS functions

SBS functions are often a higher-level abstraction on top of SB functions. A typical feature is they do not require the port parameter.


Signature mach_port_t SBSSpringBoardServerPort();
Available in 2.0 – 3.1

Get the Mach port (send right) that can communicate with the SpringBoard. The return value can be used in the SB functions.
