My best understanding of how SpringBoard manages its SBGestureRecognizers

gistfile1.m

//SpringBoard
-(void)_reloadDemoAndDebuggingDefaultsAndCapabilities{
	//..Blah blah, setting stuff up, etc.., etc...
	
	// Control Centre gesture
	SBOffscreenSwipeGestureRecognizer *gesture = [[SBOffscreenSwipeGestureRecognizer alloc] initForOffscreenEdge:0x4];
	[gesture setTypes:0x40];
	[gesture setShouldUseUIKitHeuristics:YES];
	[gesture setMinTouches:1];
