#import "CustomerNavBarController.h"@implementation UINavigationBar (UINavigationBarCategory)-(UINavigationBar*)setBackgroundImage:(UIImage*)image{UINavigationBar *NavBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];    if(image == nil) return NavBar;    bg = [[UIImageView alloc]initWithImage:image];    bg.frame = CGRectMake(0.f, 0.f, self.frame.size.width, self.frame.size.height);    [NavBar addSubview:bg];    [NavBar sendSubviewToBack:bg];    [bg release];return NavBar;}- (void)insertSubview:(UIView *)view atIndex:(NSInteger)index{    [super insertSubview:view atIndex:index];    [self sendSubviewToBack:bg];}@end

 

 

 

 

 在需要調用的地方添加如下代碼：

 

- (void)viewDidLoad {    [super viewDidLoad];   [[self.navigationController navigationBar] setBackgroundImage:[UIImage imageNamed:@"NavigationBarBackground.png"]];//在下面添加你自己的功能代碼***********}
