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 and Google.

SearchBar looking right now

What i want to achieve

I tried all these stuffs mentioned below

searchBar.layer.borderWidth = 1; searchBar.layer.borderColor = [[UIColor whiteColor] CGColor]; 

and

for (id img in searchBar.subviews) {             if ([img isKindOfClass:NSClassFromString(@"UISearchBarBackground")])      {                  [img removeFromSuperview];          } }  

and

for (UIView *sub in self.tableView.tableHeaderView.subviews) {     if ([sub isKindOfClass:[UIImageView class]]) {         sub.hidden = YES;     } }   

but still no success.

Answer 1

Set Search Style = minimal in Search Bar properties in IB

Or

Swift: searchBar.searchBarStyle = UISearchBarStyleMinimal;  Swift 3: searchBar.searchBarStyle = .minimal; 

Answer 2

Setting searchBarStyle to UISearchBarStyleMinimal messed up my color setup, so doing this instead fixed the issue.

[self.searchField setBackgroundImage:[[UIImage alloc]init]]; 

For those looking for this option in Swift 4:

searchField.setBackgroundImage(UIImage(), for: .any, barMetrics: UIBarMetrics.default)
