 if (IOS7) {


        //ios7下，tabbar选中的文字颜色

        _tabBarController.tabBar.tintColor = COLOR(245, 254, 0, 1);

    }

    else {

        //ios6下，tabbar选中的文字颜色

        [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:

                                                           COLOR(245, 254, 0, 1), UITextAttributeTextColor,nil]

                                                 forState:UIControlStateHighlighted];

    }
    //修改tabbar背景图
  _tabBarController.tabBar.backgroundImage = LOADPNGIMAGE(@"TabbarBG");


//修改选中和未选中的图片
 [viewController.tabBarItem setFinishedSelectedImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@按下.png",imageArr[i]]] withFinishedUnselectedImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@弹起.png",imageArr[i]]]];
