UINavigationController 自定义navigationBar 

 
 1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
 2 {
 3     //隐藏状态栏
 4     UIApplication *myApp = [UIApplication sharedApplication] ;
 5     [myApp setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
 6     [myApp release];
 7     
 8     self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
 9     // Override point for customization after application launch.
10     self.navigationController = [[UINavigationController alloc] init];
11     ListMagazineViewController *rootViewController = [[ListMagazineViewController alloc] init];
12     [self.navigationController pushViewController:rootViewController animated:YES];
13     [self.window addSubview:self.navigationController.view];
14     [self.window makeKeyAndVisible];
15     [rootViewController release];
16     return YES;
17 }

 

隐藏 导航栏：

self.navigationController.navigationBarHidden = YES; 

自定义 navigationBar

navigationBar = self.navigationController.navigationBar;
#define kSCNavBarImageTag 10
    
    if([navigationBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)]){
        //if ios5.0 and later
        [navigationBar setBackgroundImage:[UIImage imageNamed:@"navbarbg"] forBarMetrics:UIBarMetricsDefault];
    }else {
        UIImageView *imageView = (UIImageView *)[navigationBar viewWithTag:kSCNavBarImageTag];
        if(imageView == nil){
            imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"navbarbg"]];
            [imageView setTag:kSCNavBarImageTag];
            [navigationBar insertSubview:imageView atIndex:0];
            [imageView release];
        }
    }

 导航栏置顶于viewcontroller之上，不挤压viewcontroller属性设置：

[self.navigationController.navigationBarsetTranslucent:YES];

 

跳转新页面：

[self.navigationControllerpushViewController:imagePageViewController animated:YES];

 返回上一个页面：

[self.navigationControllerpopViewControllerAnimated:YES];
