iphone - UINavigationBar UIBarButtonItems much larger click area than required

Question

hopefully someone can help me out- iv'e scoured the net for the answer and cannot find one-

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-

also try this- click underneath the nav bar, below the button, the button clicks for about 5+ pixels below the nav bar-

my problem is this-

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-

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-

its almost like the nav bar has reserved some 5+ pixels below itself as click space-

my question is this-

can someone tell me how to make the nav bar not grab those extra 5+ pixels for its buttons?

thanks very much ;)

This is the only solution I found. Create a container of the custom button:

//Create a container for the button
UIView *buttonContainer = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 55, 44)];

//Create a smaller button
UIButton *closeButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 55, 25)];
[closeButton setTitle:@"Cancel" forState:UIControlStateNormal];
//center the title
closeButton.titleEdgeInsets = UIEdgeInsetsMake(23, 0, 0, 0);

[buttonContainer addSubview:closeButton];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:buttonContainer];
