White line under UINavigationBar in IOS 7

I have a UITableViewController with a UISearchDisplayController and UISearchBar. I'm seeing a white line under the navbar when I present the view in a UITabBarController. When I present the view modally in a UINavigationController, the line is either gray or black (I can't tell) and it looks perfectly normal. Any ideas?

Swift version of Divya's answers

    let hideLineView = UIView(frame: CGRect(x: 0, y: navigationController!.navigationBar.frame.size.height, width: view.frame.size.width, height: 1))
    hideLineView.backgroundColor = UIColor.white
    navigationController!.navigationBar.addSubview(hideLineView)

Use following line of the code : 

UIView *overlayView = [[UIView alloc] initWithFrame:CGRectMake(0, 43, 320, 1)];
[overlayView setBackgroundColor:[UIColor whiteColor]];   // set color accordingly
[navBar addSubview:overlayView]; // navBar is your UINavigationBar instance
[overlayView release];

I had the same problem too, after trying with a lot of methods,I find this way solved my problem

[[UISearchBar appearance] setBackgroundColor:[UIColor yourColor]];

write it in your viewDidLoad.

I had the same problem, couldn't figure out from where it did came from (it was present everywhere and it was NOT the shadowImage), ended up with the following fix (in my UINavigationController subclass)

// Fixes strange line under NavigationBar
{
    UIView * view = [[UIView alloc] init];
    view.backgroundColor = self.navigationBar.barTintColor;
    CGRect rect = view.frame;
    rect.origin.x = 0.f;
    rect.origin.y = self.navigationBar.frame.size.height;
    rect.size.width = self.navigationBar.frame.size.width;
    rect.size.height = 1.f;
    view.frame = rect;
    [self.navigationBar addSubview:view];
}

The white line is probably the shadowImage of navigation bar.

Try setting it as:

self.navigationController.navigationBar.shadowImage = [UIImage new];

Try setting the clipsToBounds property on the UISearchBar to YES.
