I’m at the end of Chapter 14, and instead of seeing my ActivityView showing up in my MainWindow nib when the application runs, I get a completely empty window. Not, I should emphasize, a window with an empty ActivityView, but the application window is completely empty.
I’m 100% sure this is my fault– the example code compiles correctly, which is a pretty big indication I goofed somewhere– but I’m at a loss as to how to find my mistake. I have compared my source code to the example source, and it appears to match the example code, so my guess is I didn’t hook up something right in a nib somewhere. Unfortunately, since they’re just huge blocks of unreadable XML, there’s no way (that I know of) to diff the two nibs and see what’s different between them, so I don’t know how to tell if I’ve made a mistake there or not.
