      YFNavigationController *navigation = [[YFNavigationController alloc] initWithRootViewController:childController];

      childController.title = title;

      childController.tabBarItem.image = [UIImage imageNamed:image];

      //将图片原来样子展示出来 不对其进行其他颜色渲染

      childController.tabBarItem.selectedImage = [[UIImage imageNamed:selectImage] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

      NSMutableDictionary *text = [NSMutableDictionary dictionary];

      text[NSForegroundColorAttributeName] = YFColor(123, 123, 123);

      NSMutableDictionary *selectText = [NSMutableDictionary dictionary];

      selectText[NSForegroundColorAttributeName] = YFMainColor;

      //设置文字颜色

      [childController.tabBarItem setTitleTextAttributes:text forState:UIControlStateNormal];

      [childController.tabBarItem setTitleTextAttributes:selectText forState:UIControlStateSelected];

      [self addChildViewController:navigation];

  }

• 2.自定义导航条

     ① //通过背景图片来设置导航栏的外观。

        [self.navigationBar setBackgroundImage:nil forBarPosition:UIBarPositionAny barMetrics:UIBarMetricsDefault];

         //隐藏底部黑线 

         [self.navigationController.navigationBar setShadowImage:nil];

  ②.  - (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated

        {

  　         //操作.......    

             //写在这会有一个tabbar推出效果

             [super pushViewController:viewController animated:animated];

         }
