UIBarButtonItem Offset?
===

I am trying to offset the UIBarButtonItems in my app, I need them slightly offset due to the image I use for my navigation bar so it all lines up correctly. I have managed to do this like so:

    [[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-3 forBarMetrics:UIBarMetricsDefault];
        [[UIBarButtonItem appearance] setBackgroundVerticalPositionAdjustment:-3 forBarMetrics:UIBarMetricsDefault];
        [[UIBarButtonItem appearance] setBackButtonBackgroundVerticalPositionAdjustment:-3 forBarMetrics:UIBarMetricsDefault];

I have two queries though.

1. This stops the buttons have any highlighted state, they function but are no linger visibly pressed down. Anyway around this?

2. More importantly, this works well pushing my buttons upwards in my nav bar, but it pushes them up in my toolbars as well at the bottom of the screen where I need the opposite, actually push them down a little. How can I handle this?

Any help always appreciated, thanks.
