Question

The design I’ve been given for an iPhone app I’m working on calls for a 1px red line at the bottom of the navigation bar. I know how to draw a line with Quartz and -drawRect, but how do I get access to the UINavigationBar’s view? Or would it work to draw the line in the app’s main view, on top of everything else?

Duncan Wilcox’s answer below works to get the line drawn, but then buttons on the bar become impossible to press.

If I do [self.navigationItem.titleView.superview sendSubviewToBack:titleView] then buttons that are created in nib files work, but not ones that are dynamically added.

Answer 1

This is what I’ve settled upon:

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