A custom button on Navigation

Question

I've created a custom button as an NavigationItem at the rightBarBuuttonItem. It works well, but when I click outside the button, for example a little down of the button, it still works. Here is my code

fetchButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[fetchButton setImage:[UIImage imageNamed:@"quanse.png"] forState:UIControlStateNormal];
[fetchButton addTarget:self action:@selector(searchDataByColor) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.rightBarButtonItem =[[UIBarButtonItem alloc] initWithCustomView:fetchButton];

Anybody who can tell me, what can I do to fix this bug?

did you test it on the device or in the simulator? – skytz Apr 12 '12 at 23:09 — skytz, Apr 12 '12 at 23:09

What you are describing is actually the normal behavior of the UIButton. The actual touchable area extends beyond the visible borders of the button. You can see this behavior in Apple's own apps.

Normally this is a convenience for the user, but if you find it undesirable in your app, there's a possible workaround solution in this prior question:
