Change the height of NavigationBar and UIBarButtonItem elements inside it in Cocoa Touch

Question

I suppose it\'s not strictly in line with Apple guidelines but I guess it must be possible somehow. I\'d like to change the height of navigation bar inside UINavigationContr

Answer 1

For the UINavigationbar

In iOS SDK 4.3 and beyond, there is a way (hack) to change the height of the UINavigationBar.

To change the height of UINavigationController, change its frame size in viewWillAppear:animated: function. Then, the height will stay customized throughout whole app.

For the UIBarButtonItems
I've actually run into this myself and the only thing I could come up with was leveraging initWithCustomView and passing in a UIButton with a defined frame.

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];

/*
* Insert button styling
*/

button.frame = CGRectMake(0, 0, width, height);

UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

Otherwise UIBarButtonItem only has a width property that can be set but unfortunately not a height property. Another nifty thing I've done with initWithCustomView is to pass in a toolbar with a button and other things like activity indicators. Hope this helps.
