Is there a way to change the height of a UIToolbar?

I found that if I set the frame on the iPad, when hiding/showing the Toolbar would reset itself back to a height of 44 pixels. I ended up having to override UIToolbar and change the method:

// return 'best' size to fit given size. does not actually resize view. Default is return existing view size
- (CGSize)sizeThatFits:(CGSize)size {
    CGSize result = [super sizeThatFits:size];
    result.height = 55;
    return result;
};     

This would correct adjust the height even with the hide/show.
