SpringBoard is the application launcher for the iPhone; it provides all application launching services, icon management, statusbar control, and everything else that's supposed to be filled in on this page at a later date.
Sending signal 31 to SpringBoard will rotate between these 4 logging styles:
- Stop logging.
- Start silent logging.
- Start logging to syslog.
- Dump workflow log.
SpringBoard reserves UNIX signal 30 (SIGUSR1) to toggle HID logging. It can log multitouch events, accelerometer events, button presses, etc.
Sending signal 30 to SpringBoard will rotate between these 6 logging styles:
- SpringBoard Events
- MultiTouch Gesture Events
- MultiTouch HID Events
- MultiTouch HID & Gesture Events
