使用系统UITabbarItem自定义图片显示原本颜色和自定义文字颜色

。。。。。。

 

ThirdViewController *thirdVC = [[ThirdViewControlleralloc]initWithTitle:@"搜索信息"];

    //设置tabbarItem 的图片显示原图颜色；

    thirdVC.tabBarItem = [[UITabBarItemalloc]initWithTitle:@"搜索"image:[[UIImageimageNamed:@"login_usernick"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] selectedImage:[[UIImageimageNamed:@"login_usernick_highlighted"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];

    

    //一句话改变图片和文字的颜色均为红色选中时候

//    [[UITabBar appearance]setTintColor:[UIColor redColor]];

    

//只是设置TabBarItem的字体颜色

    [[UITabBarItemappearance] setTitleTextAttributes:[NSDictionarydictionaryWithObject:[UIColorblackColor] forKey:NSForegroundColorAttributeName] forState:UIControlStateNormal];

    [[UITabBarItemappearance] setTitleTextAttributes:[NSDictionarydictionaryWithObject:[UIColorredColor] forKey:NSForegroundColorAttributeName] forState:UIControlStateSelected];

    

    

    RootNavgationController*nav3 = [[RootNavgationControlleralloc]initWithRootViewController:thirdVC];

    NSArray *VCs= [NSArray arrayWithObjects:nav1,nav2,nav3, nil];

    tabControl.viewControllers = VCs;

    self.window.rootViewController = tabControl;
