Interface Builder for Dummies: how to set the action of my button to "selectNext"?

Question

I am in "the Binding Inspector" of my button, but I don't know how to put the right information.

• I guess I have to enter information only for "Target" (not for Argument
• I bind it to "Array Controller"

But then ? I have the choice between four subsections, and don't know which one to choose !

• Controller Key ???
• Model Key Path ???
• Value Transformer ???
• or : Selector Name ???

My guess would go with "Selector Name", but Xcode doesn't give any autocompletion...

(I want to call the method selectNext)

Thank you !

Answer 1

You can not bind from Button to ArrayController.

You can Drag from ArrayController to the button.

Or,

Select ArrayController -> connection's Inspector -> Recieved Actions -> Hook "selectNext:" to the button.
