搜索.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];

This is actually simpler to do then you think. In your app delegate...
这实际上比你想象的更简单。在您的应用程序委托中...
- (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.
这将普遍改变您的导航栏背景图像。
Note:I believe UINavigationBar's"appearance" property is available in iOS 5 and up.
注意：我相信UINavigationBar's“外观”属性在 iOS 5 及更高版本中可用。

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.viewController = [[[Search alloc] initWithNibName:@"Search" bundle:nil] autorelease];
navControl = [[UINavigationController alloc] initWithRootViewController:self.viewController];
[self.window addSubview:[navControl view]];
[self.window makeKeyAndVisible];
}
}
Write this method in AppDelegate.m. I think it will be helpful to you.
在 AppDelegate.m 中编写此方法。我想它会对你有所帮助。
