iphone - How do you add more than one UIBarButton on UINavigationItem.rightBarButtonItem (or leftBarButtonItem)?

Question

I have tried this approach/hack: http://blog.blackwhale.at/2009/06/uibuttons-in-uinavigationbar/

The problem is this leaves a faint seam. I tried setting the background image of the nested toolbar to an image I captured of what it should be. That didn't work. The image was not applied. I have also tried using a nested UINavigationBar and that didn't seem to work.

I have seen this done in several iPhone apps. Does anyone know how?

[EDIT] I want the buttons to look like normal UIBarButtonItems and be able to use system styles like UIBarButtonSystemItemAdd, UIBarButtonSystemItemRefresh. The link I provided does this except you can see a faint seam because it is a UIToolbar nested in the navigationbar..

Please don't mention this breaking the Human Interface Guidelines. (We know).

I appreciate you contributing your hacks... thats the only way to do this!

iOS 5.0 now supports multiple buttons. See the iOS documentation for UINavigationItem. Specifically, the following:

Properties:

@property(nonatomic, copy) NSArray *leftBarButtonItems;
@property(nonatomic, copy) NSArray *rightBarButtonItems;
@property BOOL leftItemsSupplementBackButton;

Methods:

- (void)setLeftBarButtonItems:(NSArray *)items animated:(BOOL)animated;
- (void)setRightBarButtonItems:(NSArray *)items animated:(BOOL)animated;
