How to change the text color on UINavigationBar button items

Question

I've got a UINavigationController and i've changed it to white using the Tint property of the navigation bar in Interface Builder. But the text in buttons and the title is still the default color, white, and so gets lost against the white background. Anyone know how to work around this?

Answer 1

for (id subView in theNavigationBar.subviews) {
    if ([subView isKindOfClass:[UIButton class]]) {
        [(UIButton *)subView setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [(UIButton *)subView setTitleShadowColor:[UIColor clearColor] forState:UIControlStateNormal];
    }

}

Answer 2

As of iOS 5 this it much easier, using the UIBarButtonItem appearance proxy:

 NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys: 
                        [UIColor blackColor], 
                        UITextAttributeTextColor, 
                        [UIColor clearColor], 
                        UITextAttributeTextShadowColor, nil];

[[UIBarButtonItem appearance] setTitleTextAttributes: attributes
                                            forState: UIControlStateNormal];

Set this in application:didFinishLaunchingWithOptions:
