问题
This page shows how easily I can connect outlets http://developer.apple.com/technologies/tools/whats-new.html in Xcode 4, but I can't get it.
I right click and drag an outlet from the new referencing outlet circle, and into my header where the object is declared, but nothing happens.
Has anyone used this?
Thanks a lot

I had the same problem with the final version of Xcode 4 and solved it by selecting the File's Owner Custom Class before using the drag & drop outlet feature like shown on the screenshot below.

Also, fyi, for outlets the item has to be on a window, not just on the background. It will connect fine, but it will not process the outlet gesture. ort11

this worked for me

In my case I was dragging the outlet from "Outlets/delegate", but it must come from "Referencing outlets".
