UIBarButtonItem Appearance iOS5 Font?
===

I am using a little chunk of code like below to change the text attributes of my nav bar title app wide and it works great.

    [[UINavigationBar appearance] setTitleTextAttributes:
         [NSDictionary dictionaryWithObjectsAndKeys:
          [UIColor whiteColor], UITextAttributeTextColor,
          [UIColor grayColor], UITextAttributeTextShadowColor,
          [NSValue valueWithUIOffset:UIOffsetMake(0, -1)], UITextAttributeTextShadowOffset,
          [UIFont fontWithName:@"Cochin-BoldItalic" size:0.0], UITextAttributeFont,
          nil]];

But I want to be able to just as easily do this for UIBarButtonItem text as well but I can't figure it out as it doesn't share the same or similar methods it appears. Any help appreciated, thanks.
