Adding views over the UINavigationBar of a UINavigationController

Question

Hi!

For "skinning" purposes, I'd have to add two views over the UINavigationBar of my UINavigationController.

I did not tried anything yet, but I'd like to add a text with a background image and a toolbar over it that act as a more curtomized navigation bar (I need like previous, next, play, etc) I can't just modify the UINavigationBar because I need specific sizes and positions.

Thanks for any suggestions!
