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 = \[NSMutableDictionarydictionary\];

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

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

self.navigationController.navigationBar.titleTextAttributes = dic;
