UIKit is a high-level Objective-C framework that manages the graphical front-end of the iPhoneOS. It is a public framework, and therefore its documentation can be found on Apple's iPhone Dev Center. Nevertheless, this is only a small part of the whole UIKit.

Parameters for UIKit applications

UIKit recognizes the following these special command-line flags:

Flag	Purpose
-BuildDefaultPNG	Write the default PNG image to ~/Library/Caches/AppSnapshots/BundleID.png (by calling -[UIApplication _writeApplicationDefaultPNGSnapshot] on start up).
-RegisterForSystemEvents	Allow this app to receive system events which normally should be received by SpringBoard.
