I would like use navigationItem.title's
font, because I insert a Button in titleView
and this button have "ABC", but this "ABC" must Specified a font. I need this font same to navigationItem
title's font of system;
what do I do it?
I believe it's the regular system font [UIFont systemFontWithSize:someSize]. You'll also need to set a small shadow on it to give it the same effect that the title bar has. If you use a UILabel I believe you can set the shadowOffset to be 0,-1 for the same effect as the title bar.
