It looks to me as though it's a UIButton with an alpha of say, 0.5, ontop of a UINavigationbar with a custom background.

Try dropping something like this into your appDelegate.m

@implementation UINavigationBar (UINavigationBarCategory)
- (void)drawRect:(CGRect)rect {
UIImage *image = [UIImage imageNamed: @"navigationBar.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
@end

Alternatively you could drop in a method here,

And when you add your button to the Navigation bar..

button.alpha = 0.5;

Hope that helps
