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

Swift 2.1 in Xcode 7.2, this worked for me.

self.searchController.searchBar.backgroundImage = UIImage()

My full code below.

searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
self.searchController.searchBar.sizeToFit() 
tableView.sectionIndexBackgroundColor = UIColor(red: 0/255, green: 181/255, blue: 229/255, alpha: 1.0)
self.searchController.searchBar.backgroundColor = UIColor(red: 0/255, green: 181/255, blue: 229/255, alpha: 1.0)
self.searchController.searchBar.barTintColor = UIColor(red: 0/255, green: 181/255, blue: 229/255, alpha: 1.0)
self.searchController.searchBar.backgroundImage = UIImage()
definesPresentationContext = true
tableView.tableHeaderView = searchController.searchBar

Answer 2

Neither only barTintColor, backgroundImage nor backgroundColor alone were doing it for me, but doing them all together worked for me:

self.searchBar.translucent      = NO;
self.searchBar.barTintColor     = [styleManager currentSearchBarTintColor];
self.searchBar.backgroundImage  = [UIImage new];
self.searchBar.backgroundColor  = [styleManager currentSearchBarTintColor];

Answer 3

Set Search Style = minimal in Search Bar properties in IB

Or

Swift:
searchBar.searchBarStyle = UISearchBarStyleMinimal;

Swift 3:
searchBar.searchBarStyle = .minimal;

Answer 4

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)

Answer 5

Okay. There are so many answers, but they are too complex. I've found this solution:

Swift 3 (4)

searchBar.setBackgroundImage(UIImage(), for: .top, barMetrics: .default)
searchBar.backgroundColor = .primary

Where .primary is

extension UIColor {

    static var primary:UIColor {
        return "#5163F4".color
    }
}

Answer 6

self.searchBar.translucent = NO;
self.searchBar.opaque = NO;
if ([self.searchBar respondsToSelector:@selector(setSearchBarStyle:)]) {
    self.searchBar.searchBarStyle = UISearchBarStyleMinimal;
}

// iOS 7 remove 1 px bottom border
if ([self.searchBar respondsToSelector:@selector(setBarTintColor:)]) {
    self.searchBar.barTintColor = [UIColor clearColor];
}
self.searchBar.barStyle = UIBarStyleDefault;

// to remove the 1px bottom border iOS 5, 6
[self.searchBar setBackgroundImage:[UIImage imageWithColor:[UIColor clearColor] andSize:CGSizeMake(1.0f, 1.0f)]];

The order of code seems does matter. It doesn't work if I set the barStyle before the searchBarStyle.
