Custom logo on top of UINavigationBar?

问题

I've read plenty of requests about a full-on custom UINavigationBar background, but what I want is to overlay a logo on the default UINavigationBar instead of text. Preferably, I'd like to apply it to a subclass of UINavigationBar called CustomNavigationBar.

Neat tricks, Shadow.

If you just want to add a logo instead of a title, that's easy. Set the titleView on your navigationItem, like so:

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Logo"]];
self.navigationItem.titleView = imageView;
[imageView release];

This page has some code you can look at as he explains how to do some custom things to the nav controller. http://web.archive.org/web/20161220074043/http://foobarpig.com/iphone/uinavigationbar-with-solid-color-or-image-background.html
