对于iOS5.0以下可以使用以下办法：

UINavigationBar+CustomImage.h

#import <UIKit/UIKit.h>@interface UINavigationBar (CustomImage)- (void)drawRect:(CGRect)rect;@end

UINavigationBar+CustomImage.m

#import "UINavigationBar+CustomImage.h"@implementation UINavigationBar (CustomImage)- (void)drawRect:(CGRect)rect {    UIImage *image = [UIImage imageNamed: @"bg-header.png"];    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];}@end

iOS5以上有相应方法

//iOS 5    UIImage *imgHeaderBg = [UIImage imageNamed: @"bg-header.png"];      if ([self.navigationController.navigationBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)]) {        //iOS 5 new UINavigationBar custom background        [self.navigationController.navigationBar setBackgroundImage:imgHeaderBg forBarMetrics: UIBarMetricsDefault];    }
