For UISearchBarStyleProminent:

1) Be sure to check the "Translucent" box for the search bar in the Attributes Inspector.

2) Add the following to viewDidLoad:

self.navigationController.navigationBar.translucent = NO; // If you have a navBar
self.searchDisplayController.searchBar.translucent = NO;

Edit From @RudolfAdamkovic:

"I've found that for UISearchBarStyleProminent, executing [the following] helps. That way, you can keep it on in Storyboard."
searchBar.translucent = YES;
searchBar.translucent = NO;

For UISearchBarStyleMinimal:

In order to get the minimal search bar to not be translucent I have put together a workaround.

1) Be sure to check the "Translucent" box for the search bar in the Attributes Inspector.

2) Add the following code to viewDidLoad:

self.navigationController.navigationBar.translucent = NO;
self.searchDisplayController.searchBar.translucent = NO;
self.searchDisplayController.searchBar.backgroundColor = [UIColor desiredColor];

3) A UIView needs to be added to the viewController. This view needs to be 20px heigh and should have the same color as the searchBar.barTintColor.

Note: I think this workaround is needed because: "The style UISearchBarStyleMinimal provides no default background color or image but will display one if customized as such." Thus the only way to get this functionality for UISearchBarStyleMinimal is to set the backgroundColor.

See UISearchBar documentation for more details.

None of the above answers worked for me on iOS 7/8. Here's some setup code that did the trick:

searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.view.frame), 44)];
searchBar.scopeButtonTitles = @[@"Scope1", @"Scope2"];
searchBar.selectedScopeButtonIndex = 0;
searchBar.backgroundColor = [UIColor clearColor];
searchBar.barTintColor = [UIColor clearColor];
searchBar.translucent = YES; // SUPER IMPORTANT, REMOVING THIS MESSED UP THE SCOPE BAR

// ONLY USE IMAGES, NOT BACKGROUND COLORS
UIImage *searchBarBackgroundImage = [[UIImage imageNamed:@"SearchBarBackgroundImage"];
UIImage *scopeBarBackgroundImage = [[UIImage imageNamed:@"ScopeBarBackgroundImage"];
[searchBar setBackgroundImage:searchBarBackgroundImage
               forBarPosition:UIBarPositionAny
                   barMetrics:UIBarMetricsDefault];
searchBar.scopeBarBackgroundImage = scopeBarBackgroundImage;
searchBar.tintColor = [UIColor whiteColor];
