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_bgforBarMetrics:UIBarMetricsDefault]; //设置背景

[nav1.navigationBarsetBarStyle:UIBarStyleBlack];

设置Title颜色

NSMutableDictionary *dic = [NSMutableDictionarydictionary];

[dic setObject:[UIColorwhiteColor]forKey:UITextAttributeTextColor];

[dic setObject:[UIFontsystemFontOfSize:19]forKey:UITextAttributeFont];

self.navigationController.navigationBar.titleTextAttributes = dic;
