UINavigationController和UITabBarController合用。

TabPage1 *firstViewControlle = [[TabPage1 alloc] init];
    UINavigationController *nav1 = [[UINavigationController alloc] initWithRootViewController: firstViewControlle];
    UITabBarItem *time = [[UITabBarItem alloc] initWithTitle: @"First" image: nil tag: 0];
    time.image = [UIImage imageNamed:@""];
    nav1.tabBarItem = time;
    
    TabPage2 *secondViewController = [[TabPage2 alloc] init];
    UINavigationController *nav2 = [[UINavigationController alloc] initWithRootViewController: secondViewController];
    UITabBarItem *time2 = [[UITabBarItem alloc] initWithTitle: @"second" image: nil tag: 1];
    nav2.tabBarItem = time2;
    
    UITabBarController *tabBarController = [[UITabBarController alloc] init];
    NSArray *array = [NSArray arrayWithObjects: nav1,nav2, nil];
    tabBarController.viewControllers = array;
    
    [self presentViewController:tabBarController animated:YES completion:nil];



///////////在TabPage1中
self.navigationitem.title = @"111";

 //设置Navigation Bar背景图片

   UIImage *title_bg = [UIImageimageNamed:@"头.png"]; //获取图片

    CGSize titleSize =self.navigationController.navigationBar.bounds.size; //获取Navigation Bar的位置和大小

    //title_bg.size = [self scaleToSize:title_bg size:titleSize];//设置图片的大小与Navigation Bar相同

 [nav1.navigationBarsetBackgroundImage:title_bg forBarMetrics:UIBarMetricsDefault]; //设置背景

 [nav1.navigationBarsetBarStyle:UIBarStyleBlack];

设置Title颜色

    NSMutableDictionary *dic = [NSMutableDictionary dictionary];

    [dic setObject:[UIColor whiteColor] forKey:UITextAttributeTextColor];

    [dic setObject:[UIFont systemFontOfSize:19] forKey:UITextAttributeFont];

    self.navigationController.navigationBar.titleTextAttributes = dic;
