Can anybody explain if there’s a difference between dragging and ctrl-dragging in interface builder? because you can also connect targets, buttons and objects without using the ctrl-key…
The bottom line is just connecting.
If you control-click to bring up a contextual menu with circles to indicate connections, dragging from those (sans control) is fine.
If you don’t bring up the contextual menu, then I believe control-dragging is necessary. (When I tried just dragging, sans control, it wanted to move things around.)
