Please try this one. I have used in my application once and hope it will help you too.

This is how I have created Tab bar programmatically :

      UITabBarController *tab = [[UITabBarController alloc]init];
       ViewController1 *v1 = [[ViewController1 alloc]init];
        ViewController1 *v2 = [[ViewController1 alloc]init];
        ViewController1 *v3 = [[ViewController1 alloc]init];
       ViewController1 *v4 = [[ViewController1 alloc]init];

        tab.viewControllers = [NSArray arrayWithObjects:v1,v2,v3,v4,nil];

        [[tab.tabBar.items objectAtIndex:0]setImage:[UIImage imageNamed:@""]];

        [[tab.tabBar.items objectAtIndex:1]setImage:[UIImage imageNamed:@""]];

        [[tab.tabBar.items objectAtIndex:2]setImage:[UIImage imageNamed:@""]];

        [[tab.tabBar.items objectAtIndex:3]setImage:[UIImage imageNamed:@""]];

         int divide = 4;
         if([UIDevice currentDevice].userInterfaceIdiom ==UIUserInterfaceIdiomPad)
            divide =6;
        UIView *view = [[UIView alloc]initWithFrame:CGRectMake(tab.tabBar.frame.origin.x,tab.tabBar.frame.origin.y, self.view.frame.size.width/divide, 56)];

        UIImageView *border = [[UIImageView alloc]initWithFrame:CGRectMake(view.frame.origin.x,view.frame.size.height-6, self.view.frame.size.width/divide, 6)];

        border.backgroundColor = “your color”;
        [view addSubview:border];
        [tab.tabBar setSelectionIndicatorImage:[self ChangeViewToImage:view]];

//This is the method that will draw the underline

-(UIImage ) ChangeViewToImage : (UIView ) viewForImage{

[viewForImage.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
return img;
