I'm following the XCode tutorials on O'Reilly's macdevcenter.com, specifically:


On page four of that tutorial it discusses adding sliders, and then modifying the sliders NIB file in Interface builder to generate classes which can then be modified.

My problem: This tutorial was written over six years ago -- that's 42 in developer years -- and I can't figure out how to do this with a more recent version. From the middle of page four, just under the graphic, where the author writes: "I have configured the sliders such that they are small..." to the bottom, I can't figure it out in XCode 3.0.

The attributes editor seems completely different than what's pictured here. Any suggestions?
