Question

I try change to background of navigationBar.

Search.h:

#import <UIKit/UIKit.h>

@interface Search : UIViewController

@end

Search.m:

#import "Search.h"

@implementation Search

- (void)viewDidLoad
{

[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

UIImage *image = [UIImage imageNamed:@"navigation_header.png"];

[self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];

}

I can’t change navigation background.

Thanks.

This is actually simpler to do then you think. In your app delegate…

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"NavBar.png"] forBarMetrics:UIBarMetricsDefault];
    return YES;
}

This will universally change your navigation bar background image.

Note: I believe UINavigationBar's “appearance” property is available in iOS 5 and up.
