How to increase the titelBar Height?

How can I increase开发者_运维问答 the height of a titleBar ?

Completely untested, but it should work like this: In your UIViewController's viewDidLoad method, do this:

CGRect frame = self.navigationController.navigationBar.frame;
frame.size.height = 123;
[self.navigationController.navigationBar setFrame:frame];

Edit: According to this SO question it looks like you cannot change the height of a UINavigationBar at all.
