Remove Border of UISearchBar in iOS7

Question

I\'m trying to remove border of UISearchBar in iOS 7. In iOS 6 it\'s working fine. I created the UISearchBar programatically. I tried almost every thing from Stack Overflow

Answer 1

Set Search Style = minimal in Search Bar properties in IB

Or

Swift:
searchBar.searchBarStyle = UISearchBarStyleMinimal;

Swift 3:
searchBar.searchBarStyle = .minimal;
