My current tab bar looks as follows:

My code is as follows:

-(void)startTabBar{
     self.tabBarController = [[UITabBarController alloc] init];
     TAB_1  *tab_1 = [[TAB_1 alloc]init];
     TAB_2  *tab_2 = [[TAB_2 alloc]init];
     TAB_3  *tab_3 = [[TAB_3 alloc]init];

    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary  dictionaryWithObjectsAndKeys: [UIColor blackColor], NSForegroundColorAttributeName, nil] forState:UIControlStateNormal];
   [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor redColor], NSForegroundColorAttributeName,nil] forState:UIControlStateSelected];

    NSArray* controllers = [NSArray arrayWithObjects:tab_1,tab_2, tab_3, nil];

   self.tabBarController.viewControllers = controllers;
   self.window.rootViewController = self.tabBarController;
}

This accomplishes what you're asking for:

[[UITabBar appearance] setSelectedImageTintColor:[UIColor redColor]];
[[UITabBar appearance] setAlpha:0.25];
