So, I was just going over this chapter and specifically the part where our TouchDrawView is added to the MainWindow via Interface Builder. The view however is never actually configured to load in the book, or I’m missing something.
Anyway, this is what you need to do to make this work:
[li] Drag a View Controller to the workarea[/li]
[li] Link the newly added View Controller to the instance of “Touch Draw View” via its view outlet[/li]
[li] Select the Window and connect its rootViewController outlet to the View Controller[/li][/ul]
