Navigation bar "prompt" height

yes · 07-01-2009, 01:27 AM

Hi all,

The navigation bar is 44 pixels in height but what is it when "prompt" is set with text? By my calculations it expands to 74 pixels but I really don't want to hard code this number in case it changes in the future.

The following returns 44 (as it should) but it still reports 44 even when the prompt is showing:

self.navigationController.navigationBar.frame.size .height

Any ides?

Justin.

The reason was because I read the variable before the default animation had finished so the value had yet to be updated.

This is fine once the animation has finished, but is it possible to read that default value (of 74 pixels) from a constant somewhere? Is there a magic header file somewhere with UI constants?
