Why is setting my UINavigationBar's background image affecting the size of the navigation bar?

Question

I'm doing something like this:

UIImage *barBackgroundImage = [UIImage imageNamed:@"myImage.png"];
[[UINavigationBar appearance] setBackgroundImage:
                                    backgroundImage
                                   forBarMetrics:UIBarMetricsDefault];

And the resulting UINavigationBar is much larger than the standard navigation bar. I'm aware that my image size might be the problem. Is there any way to take care of this programmatically?

Answer 1

This is how I set the UINavigationController's navigationBar background image.

[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbar.png"] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setTintColor:LIGHTBROWN];

navbar.png is 320x44 and respectively 640x88 for [email protected].

Follow this link to make your code compatible with iOS4, 5 and 6: http://robert-varga.com/?p=735

You just have to make in Photoshop or other software a rectangular with the size of 320x44 or 640x88 (for retina display) and import it to your project
