I’m just getting back into the swing of things with Interface Builder after a little bit of a gap, and one of the first things I’ve noticed is that somewhere between the 2.2.1 and the most current 3.0 SDK’s, Apple have added a new special colour to the iPhone SDK, called “groupTableViewBackgroundColour”.
Previously it seemed you could only get this when creating your own grouped table view, but they’ve eased things off now so you can use it in regular views too. Nice!
