I'm fumbling my way through one and it feels awkward.
The most straightforward way to do this is probably going to be creating a custom CAAnimation that drives the position of the views which are moving around, as well as a property of the "connections" layer that encodes the positions between which lines should be drawn. The connections layer can return YES for +needsDisplayForKey: for that "line endpoints" key. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
