  一、RDVTabBarController的功能性代码介绍：

  1.设置角标数

   [[self rdv_tabBarItem] setBadgeValue:@"3"];

  2.RDVTabBarControllerDelegate代码

  /**
   * Asks the delegate whether the specified view controller should be made active.
   */
  - (BOOL)tabBarController:(RDVTabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController;
  
  
  /**
   * Tells the delegate that the user selected an item in the tab bar.
   */
  - (void)tabBarController:(RDVTabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController;

  3.RDVTabBarController的底部tabbar字体与图片修改

  - (void)customizeTabBarForController{
  
      //tabbar 背景图片 tabbar_background
      UIImage *backgroundImage = [UIImage imageNamed:@"tabbar_background"];
      //选项卡图片
      NSArray *tabBarItemImages;
        //这里添加tabBar icon图片
      //= @[VString(@"First"), VString(@"Second"),VString(@"Third")];
  
      NSArray *tabBarItemTitles = @[@"Home", @"Found", @"Me"];
      NSInteger index = 0;
      for (RDVTabBarItem *item in [[self tabBar] items])
      {    //tabbarItem位置设置
          item.titlePositionAdjustment = UIOffsetMake(0, 2.0);
          [item setBackgroundSelectedImage:backgroundImage withUnselectedImage:backgroundImage];
          UIImage *selectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_selected",[tabBarItemImages objectAtIndex:index]]];
  
          UIImage *unselectedimage = [UIImage imageNamed:[NSString stringWithFormat:@"%@_normal",[tabBarItemImages objectAtIndex:index]]];
  
          [item setFinishedSelectedImage:selectedimage withFinishedUnselectedImage:unselectedimage];
  
          [item setTitle:[tabBarItemTitles objectAtIndex:index]];
          item.selectedTitleAttributes = @{
                                           NSFontAttributeName: [UIFont boldSystemFontOfSize:12],
                                           NSForegroundColorAttributeName:kNAVIGATION_BAR_COLOR,
                                           };
          item.unselectedTitleAttributes = @{
                                             NSFontAttributeName: [UIFont boldSystemFontOfSize:12],
                                             NSForegroundColorAttributeName:RGB(217, 217, 217),
                                             };
  
          [item setTitle:[tabBarItemTitles objectAtIndex:index]];
          index++;
  
      }
  }

  4.VString宏定义，为了就是更好的国际化语言，适配多语言，刚好此Demo也国际化了

  #define VString(x)      NSLocalizedString(x, nil)
