I have no idea what stackoverflow is suggesting here but it looks entirely
wrong as usual for that junky site. You're just creating a standalone I
referenced object.
Right click your view in IB then wait a second and right click it again. I
think it's right clicks. You will then get the outlet panel which is the grey
HUD display with all the outlets and actions. You can drag connect to your
buttons. There's some ctrl alt shift cmd combo which does this too but I never
remember it. You can still connect view outlets as before, just that ctrl-drag
was repurposed a couple of xcodes ago for auto layout so you have to work a
little harder to get the inspector up.
