I just Testing Bellow few line of Code and it works very nice, just test it in to your Project. hope you'll get your solution easily.

Why to create new View and adding it into your existing view..? For this task simply create one CALayer and add it into your existing UIView's Layer do as following:-

#import <QuartzCore/QuartzCore.h>
- (void)viewDidLoad
{
    CALayer *TopBorder = [CALayer layer];
    TopBorder.frame = CGRectMake(0.0f, 0.0f, myview.frame.size.width, 3.0f);
    TopBorder.backgroundColor = [UIColor redColor].CGColor;
    [myview.layer addSublayer:TopBorder];

  [super viewDidLoad];

}

and It's Output is:-
