hi i've been trying the pdf tutorial and it works great... up to a point.. The problem comes when i try to hook up the slider with the ctrl click and drag. It works fine for textboxes which are highlighted as soon as i hover over them but when i ctrl click the controller and then drag the blue line to the slider nothing happens.. i am using interface builder 3.1.2 by the way. I would appreciate any help. PS.: it does work the other way around though, i can ctrl click and drag from the slider to the controller and it offers to set one of the methods but i guess that doesnt really help.. EDIT: ok i think I have it. The problem was that when I defined the IBOutlets as type id interface builder didnt recognize them as compatible so I had to change them to the specific matching types..
