Change position of UIBarButtonItem in UINavigationBar

Question

How can I change the position of a UIBarButtonItem in a UINavigationBar? I would like my button to be about 5px higher than its normal position.

The best way is to subclass your UINavigationBar, as described here: https://stackoverflow.com/a/17434530/1351190

Here is my example:

#define NAVIGATION_BTN_MARGIN 5

@implementation NewNavigationBar

- (void)layoutSubviews {

    [super layoutSubviews];

    UINavigationItem *navigationItem = [self topItem];

    UIView *subview = [[navigationItem rightBarButtonItem] customView];

    if (subview) {

        CGRect subviewFrame = subview.frame;
        subviewFrame.origin.x = self.frame.size.width - subview.frame.size.width - NAVIGATION_BTN_MARGIN;
        subviewFrame.origin.y = (self.frame.size.height - subview.frame.size.height) / 2;

        [subview setFrame:subviewFrame];
    }

    subview = [[navigationItem leftBarButtonItem] customView];

    if (subview) {

        CGRect subviewFrame = subview.frame;
        subviewFrame.origin.x = NAVIGATION_BTN_MARGIN;
        subviewFrame.origin.y = (self.frame.size.height - subview.frame.size.height) / 2;

        [subview setFrame:subviewFrame];
    }
}

@end

Hope it helps.
