How do I remove the horizontal padding to the left and right of custom left and right UINavigationBar items? There seems to be ~ 10 points of padding that iOS sets by default.
I'm customizing left and right navigation bar buttons (I have given up on trying to set my own backButtonItem, so I'm just using the leftBarButtonItem).
In either case (left or right), pressing these custom buttons indicates that Apple seems to preserve some padding to the left of the leftBarButtonItem, and to the right of the rightBarButtonItem; regardless of how wide I make the custom background and image properties of the UIButton I place inside the left/right bar button item as its custom view.
Since UIBarButtonItems have no "frame" I can access, I can't position them within their superview like I can normal UIViews.
Any suggestions on how to remove this default padding? See screen shot attached to see the bit I'm trying to reduce to a zero width. In the screen shot, the plus icon appears shifted to the right because I gave it an inset; but the highlighted background image, also presumably using that inset, is getting clipped on its right side).

For reference, here's how I'm creating my custom UIBarButtonItem (in this case, it's the right button):
- (UIBarButtonItem *)customAddButtonItemWithTarget:(id)target action:(SEL)action {
UIButton *customButtonView = [UIButton buttonWithType:UIButtonTypeCustom];
customButtonView.frame = CGRectMake(0.0f, 0.0f, 45.0f, 44.0f);
[customButtonView setBackgroundImage:
[UIImage imageNamed:@"bgNavBarButton-OutsideRight-Normal.png"]
forState:UIControlStateNormal];
[customButtonView setBackgroundImage:
[UIImage imageNamed:@"bgNavBarButton-OutsideRight-Highlighted.png"]
forState:UIControlStateHighlighted];
[customButtonView setImage:
[UIImage imageNamed:@"bgNavBarButton-Add-Normal.png"]
forState:UIControlStateNormal];
[customButtonView setImage:
[UIImage imageNamed:@"bgNavBarButton-Add-Highlighted.png"]
forState:UIControlStateHighlighted];
[customButtonView addTarget:target action:action
forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customButtonItem = [[[UIBarButtonItem alloc]
initWithCustomView:customButtonView] autorelease];
[customButtonView setImageEdgeInsets:UIEdgeInsetsMake(0.0f, 10.0f, 0.0f, 0.0f)];
//customButtonItem.imageInsets = UIEdgeInsetsMake(0.0f, 10.0f, 0.0f, 0.0f);
return customButtonItem;
}
