iOS How to know width of detail view in split controller?

[mikezang]

I changed detail view to detail table view in spilt controller, so that I have to create UINavigationBar in programming.

I found the table view's frame is in (0, 20, 768, 1004), but I need 704 in landscape mode and 768 in Portrait mode.

How can I get true width of super view of navigationBar?

This is a big annoyance for me as well, I've taken to just using the interfaceOrientation variable and using what I know the width should be.
