Mike,
you need a view that has the size of the window to cover it
completely. Otherwise touches will go down the responder chain and
reach other views.
What happens while you show the spinner?
If you load data from the net show the UIApps spinner at the top.

No, there is no race. While the nib is being loaded, there are plenty
of references to the objects therein on the stack and in registers.
These references will keep these objects alive during loading.

Unfortunately, this is an Apple bug.
What Content-Type does the server return, and can you control that? If
