  <p>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.</p>
  
  <p>I have seen this done in several iPhone apps. Does anyone know how?</p>
  
  <p>[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..</p>
  
  <p>Please don't mention this breaking the Human Interface Guidelines. (We know).</p>
  
  <p>I appreciate you contributing your hacks... thats the only way to do this!</p>
