title: UINavigationBar UIBarButtonItems much larger click area than required
body: <p>hopefully someone can help me out- iv'e scoured the net for the answer and cannot find one-</p>
  
  <p>the UIBarButtonItems added to UINavigationBar have a much larger click area than required-
  for example, open up any project you have a nav bar with buttons on- click anywhere between the end of the button and the title of the nav bar- the button clicks, when you clearly did not click on the button-</p>
  
  <p>also try this- click underneath the nav bar, below the button, the button clicks for about 5+ pixels below the nav bar-</p>
  
  <p>my problem is this-</p>
  
  <p>i have added a custom header with buttons to a tableview- but when i click the buttons in the header, the UINavigationBar buttons trigger for those 5+ pixels instead of the buttons in the tableview header-</p>
  
  <p>i did a test, and removed the buttons from UINavigationBar and what is interesting is that for the 5 pixels below the nav bar, the buttons in the header will not trigger even though there are no buttons in the nav bar-</p>
  
  <p>its almost like the nav bar has reserved some 5+ pixels below itself as click space-</p>
  
  <p>my question is this-</p>
  
  <p>can someone tell me how to make the nav bar not grab those extra 5+ pixels for its buttons?</p>
  
  <p>thanks very much ;)</p>
