UISearchBarSearchField BackgroundView color

Question

I am trying to change the background color of the search bar text field and i have searched and tried lots of solutions but those are not working.

So, please anyone can tell me the exact solution for that. How can we change the background color of the search bar text field?

/// used to prepare searchController inside navigation.
private func prepareNavigationSearchControllerSetup() {
    self.title = AppConstant.kContacts
    let search = UISearchController(searchResultsController: nil)
    search.searchResultsUpdater = self
    search.searchBar.cornerRadius = 10.0
    search.searchBar.textField?.backgroundColor = .red
    search.searchBar.textField?.tintColor = .yellow
    self.navigationItem.searchController = search
    self.navigationItem.hidesSearchBarWhenScrolling = false
}

extension UISearchBar {

    var textField: UITextField? {
        let subViews = subviews.flatMap { $0.subviews }
        return (subViews.filter { $0 is UITextField }).first as? UITextField
    }
}

After a lot more search I found the correct answer that is working for me.

if #available(iOS 11.0, *) {
        if let textfield = search.searchBar.value(forKey: "searchField") as? UITextField {
            textfield.textColor = UIColor.blue

            if let backgroundview = textfield.subviews.first {
                backgroundview.backgroundColor = UIColor.white
                backgroundview.layer.cornerRadius = 10;
                backgroundview.clipsToBounds = true;
            }
        }

  }

You can try this

UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).backgroundColor = .yellow
UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).tintColor = .blue

Output

Edit : Full Code

    var searchController = UISearchController()
    let resultsTableController = Storyboard.Home.instantiateViewController(withIdentifier: "GlobalTableVC") as! GlobalTableVC
    resultsTableController.tableView.delegate = self
    resultsTableController.tableView.dataSource = self

    resultsTableController.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "SearchCell")

    searchController = UISearchController(searchResultsController: resultsTableController)
    searchController.searchBar.placeholder = "Search"
    searchController.dimsBackgroundDuringPresentation = true
    searchController.searchBar.sizeToFit()
    searchController.hidesNavigationBarDuringPresentation = false
    searchController.searchBar.keyboardType = UIKeyboardType.alphabet
    searchController.searchBar.tintColor = UIColor.white
    searchController.searchBar.barTintColor = UIColor(hexString: "EB033B")

    UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).backgroundColor = .yellow
    UITextField.appearance(whenContainedInInstancesOf: [type(of: searchController.searchBar)]).tintColor = .blue


    searchController.searchBar.delegate = self
    searchController.delegate = self
    searchController.searchResultsUpdater = self

    present(searchController, animated: true, completion: nil)

Now (iOS 13.X) UISearchBar directly we can access UISearchBar.searchTextField so we can directly replace our private API implementation to public API.

Objective - C

searchBar.searchTextField.backgroundColor = [UIColor blueColor];

Swift

public extension UISearchBar {

func changeborderColor(){
    self.searchTextPositionAdjustment = UIOffset.init(horizontal: 10.0, vertical: 0.0)
    let divideCount: CGFloat = 255.0

    if #available(iOS 13.0, *) {
        self.searchTextField.backgroundColor = .red
        var placeHolderText = " "
        if let getplaceHolder = self.searchTextField.placeholder, !getplaceHolder.isEmpty {
            //print(getplaceHolder)
            placeHolderText = getplaceHolder
        }

        self.searchTextField.placeholder = placeHolderText

        let placeholderAttributedString = NSMutableAttributedString(attributedString: self.searchTextField.attributedPlaceholder!)

       placeholderAttributedString.addAttribute(.foregroundColor, value: UIColor.XTRMWhite, range: NSRange(location: 0, length: placeholderAttributedString.length))
       self.searchTextField.attributedPlaceholder = placeholderAttributedString

        self.searchTextField.textColor =  UIColor(red: 129.0/divideCount, green: 170.0/divideCount, blue: 200.0/divideCount, alpha: 1.0)
        //Magnifying glass
        let glassIconView = searchTextField.leftView as? UIImageView
        glassIconView?.image = glassIconView?.image?.withRenderingMode(.alwaysTemplate)
        glassIconView?.tintColor = .white
        DispatchQueue.main.async {
            self.searchTextField.underlined()
        }

    }else{

    if let searchTextField = self.value(forKey: "_searchField") as? UITextField, let clearButton = searchTextField.value(forKey: "_clearButton") as? UIButton {
        // Create a template copy of the original button image
        // Set the template image copy as the button image
        // clearButton.setImage(clearButton.imageView?.image, for: .normal)
        // Finally, set the image color
        clearButton.tintColor = .white

        if let textFieldInsideSearchBarLabel = searchTextField.value(forKey: "placeholderLabel") as? UILabel {
            textFieldInsideSearchBarLabel.textColor = .white
        }

        searchTextField.backgroundColor = .red
        searchTextField.textColor =  UIColor(red: 129.0/divideCount, green: 170.0/divideCount, blue: 200.0/divideCount, alpha: 1.0)
        //Magnifying glass
        let glassIconView = searchTextField.leftView as? UIImageView
        glassIconView?.image = glassIconView?.image?.withRenderingMode(.alwaysTemplate)
        glassIconView?.tintColor = .white
        DispatchQueue.main.async {
            searchTextField.underlined()
        }

    }
    }

}

 }

access the method as like

   @IBOutlet weak var searchCurrency: UISearchBar!{
    didSet{
        searchCurrency.delegate = self
        searchCurrency.changeborderColor()
    }
}

Since iOS 13:

        if #available(iOS 13.0, *) {
            searchController.searchBar.searchTextField.backgroundColor = .red
            searchController.searchBar.searchTextField.tintColor = .yellow
        }
