[[UITabBarItem appearance]setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12.0f],NSForegroundColorAttributeName:[UIColor colorWithRed:1.000green:0.314blue:0.000alpha:1]}forState:UIControlStateSelected];
HomeViewController*homeVC = [[HomeViewController alloc]initWithNibName:nil bundle:nil];
homeVC.tabBarItem= [[UITabBarItem alloc]initWithTitle:@"商城"image:[UIImage imageNamed:@"menu_home_off"]selectedImage:[self originalImageName:@"menu_home_on"]];
UINavigationController*homeNavigation = [[UINavigationController alloc]initWithRootViewController:homeVC];
LocalViewController*localVC = [[LocalViewController alloc]initWithNibName:nil bundle:nil];
localVC.tabBarItem= [[UITabBarItem alloc]initWithTitle:@"本地"image:[UIImage imageNamed:@"menu_merchant_off"]selectedImage:[self originalImageName:@"menu_merchant_on"]];
UINavigationController*localNavigation = [[UINavigationController alloc]initWithRootViewController:localVC];
ShoppingCarViewController*shoppingCarVC = [[ShoppingCarViewController alloc]initWithNibName:nil bundle:nil];
shoppingCarVC.tabBarItem= [[UITabBarItem alloc]initWithTitle:@"购物车"image:[UIImage imageNamed:@"menu_cart_off"]selectedImage:[self originalImageName:@"menu_cart_on"]];
UINavigationController*shoppingCarNavigation = [[UINavigationController alloc]initWithRootViewController:shoppingCarVC];
MyViewController*myVC = [[MyViewController alloc]initWithNibName:nil bundle:nil];
myVC.tabBarItem= [[UITabBarItem alloc]initWithTitle:@"我的"image:[UIImage imageNamed:@"menu_account_off"]selectedImage:[self originalImageName:@"menu_account_on"]];
UINavigationController*myNavigation = [[UINavigationController alloc]initWithRootViewController:myVC];
UITabBarController*tabBarController = [[UITabBarController alloc]initWithNibName:nil bundle:nil];
tabBarController.viewControllers=@[homeNavigation,localNavigation,shoppingCarNavigation,myNavigation];
[UIApplication sharedApplication].delegate.window.rootViewController= tabBarController;
封装一个返回image的方法,用来设置tabBarItem的背景图片,使用原始图像
- (UIImage*)originalImageName:(NSString*)imageName
{
UIImage *img = [UIImage imageNamed:imageName];
return [img imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}
设置tabbarItem下方文字被选中时的颜色
[[UITabBarItem appearance]setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12.0f],NSForegroundColorAttributeName:[UIColor colorWithRed:1.000green:0.314blue:0.000alpha:1]}forState:UIControlStateSelected];
效果如图:
