When I looked at their values in the debugger, I found that _resultsTable was an instance of UITableView, not MyTableView; and _searchActivityIndicator and _searchBar were both nil.

Yes, I put a breakpoint in -viewDidLoad, as well as just letting it run and crash, and then look at the instance variables in the debugger. At both places, the table is a UITableView and the other two outlets are nil.

Yes, the Type field in the xib file's main window, as well as the Class field in the inspector window, show the type as MyTableView.

Yes, the outlets tab in the inspector window shows the file owner/view controller's outlets to be all wired up. And moving the mouse over those items highlights the corresponding views in the main xib window.

Yes.
> 5) you are not instantiating your controller twice? The MainWindow.xib template for tab-based targets does it; do you do it elsewhere yourself?
No, my MainWindow.xib has a tab bar controller that has a tab item referencing this view controller and its corresponding nib file.

Yes, and the controller is being instantiated as expected.
