Dev:SBIcon

From The Apple Wiki

SBIcon is a class representing an icon displayed by SpringBoard. It is not typically used directly; instead, its various subclasses are used: SBApplicationIcon, SBBookmarkIcon, SBDownloadingIcon, and SBDestinationHole (which is a blank space used when rearranging icons).

In iOS 5 Apple split up SBIcon, creating a separate class for SBIconView, and just leaving SBIcon with behind the scenes stuff.

Launching an Application using SBIcon

[icon launchFromLocation:iconLocation];

For SBIcon locations, see Dev:SBIconView#SBIconViewLocation.

Getting an SBIcon

SBIconController *controller = [%c(SBIconController) sharedInstance];
SBIconModel *model = [controller model];
SBIcon *icon = [model expectedIconForDisplayIdentifier:iconIdentifier];
