In viewDidLoad():
searchController = UISearchController(searchResultsController: nil)
let cancelButtonAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(cancelButtonAttributes, for: .normal)
searchController?.dimsBackgroundDuringPresentation = false
searchController?.searchResultsUpdater = self
searchController?.delegate = self
searchController?.searchBar.tintColor = UIColor.black
searchController?.searchBar.barTintColor = UIColor(white: 0.9, alpha: 0.9)
searchController?.searchBar.placeholder = NSLocalizedString("Search", comment: "")
searchController?.hidesNavigationBarDuringPresentation = false
self.navigationItem.titleView = self.searchController?.searchBar
searchController?.isActive = true
self.searchController?.becomeFirstResponder()
self.searchController?.searchBar.becomeFirstResponder()
Here is the delegate method:
extension SearchMembers : UISearchControllerDelegate {
func didPresentSearchController(searchController: UISearchController){
self.searchController?.searchBar.becomeFirstResponder()
}
}
In my test didPresentSearchController(searchController:) is never called.
I don't know why but whatever I do just doesn't work.
Any idea?
EDIT
The only solution that works
delay(0.6) {
self.searchController?.searchBar.becomeFirstResponder()
}
Which creates an unwanted lag
According to the documentation of didPresentSearchController:
This method is only called when the search controller is automatically presented. It is not called if you explicitly present the search controller.
If you want to present the search results interface explicitly, wrap your search controller in a UISearchContainerViewController object and present that object instead.

I am getting idea of a new app. I love to find a many tricks. however, No luck for me.
The simple.
You can see swipe down the search bar from the below of the navigation bar.
Result:
// iOS 13 Navigation Bar only
self.navigationItem.title = "Search Title"
self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.navigationItem.largeTitleDisplayMode = .never
UINavigationBar.appearance().isTranslucent = false
let app = UINavigationBarAppearance()
let navigationBar = self.navigationController?.navigationBar
app.backgroundColor = .clear
app.configureWithOpaqueBackground()
app.titleTextAttributes = [.foregroundColor: UIColor.label]
app.largeTitleTextAttributes = [.foregroundColor: UIColor.label]
app.backgroundColor = .systemGroupedBackground
self.navigationController?.navigationBar.scrollEdgeAppearance = app
navigationBar!.standardAppearance = app
navigationBar!.scrollEdgeAppearance = app
Search Result:
// Search Bars
let search = UISearchController(searchResultsController: nil)
search.searchBar.delegate = self
search.searchResultsUpdater = self as? UISearchResultsUpdating
search.searchBar.placeholder = "Search"
search.searchBar.searchTextField.tintColor = UIColor.gray
search.searchBar.setImage(UIImage(named: "magnifyingglass")?.withTintColor(UIColor.systemGray), for: .search, state: .normal)
self.navigationItem.searchController = search
(UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]) ).defaultTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.init(white: 100, alpha: 0.50)]
let textField = search.searchBar.value(forKey: "searchField") as! UITextField
let glassIconView = textField.leftView as! UIImageView
glassIconView.image = glassIconView.image?.withRenderingMode(.alwaysTemplate)
glassIconView.tintColor = UIColor.systemGray
let clearButton = textField.value(forKey: "clearButton") as! UIButton
clearButton.setImage(clearButton.imageView?.image?.withRenderingMode(.alwaysTemplate), for: .normal)
clearButton.tintColor = UIColor.systemGray
Now, I am tried to look for the trick code to set the search bar's text will appear navigation bar when you have searched it. (Yes, It is a very familiar to Safari style).
I don't like Search Bar title text stayed on the small of the search bars, so move to a large title look better.
Let me know. :)
You can use searchBarSearchButtonClicked method of UISearchBarDelegate.
(https://developer.apple.com/documentation/uikit/uisearchbardelegate/1624294-searchbarsearchbuttonclicked)
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
self.navigationItem.title = searchBar.text ?? "Search Title"
}
If you need to update the title as the user types in search bar, use updateSearchResults of UISearchResultsUpdating. (https://developer.apple.com/documentation/uikit/uisearchresultsupdating/1618658-updatesearchresults)
func updateSearchResults(for searchController: UISearchController) {
self.navigationItem.title = searchController.searchBar.text ?? "Search Title"
}

I tried solutions to all relevant questions. However none of them helped really.
I am getting a weird gap between table view and search bar when search bar shows results.
Help me find out what's wrong with my code:
the view controller subclasses from UITableViewController, UISearchBarDelegate, UISearchResultsUpdating
var searchController = UISearchController()
var resultsController = UITableViewController()
var refreshController = UIRefreshControl()
in override :
configureSearchController()
resultsController.tableView.delegate = self
resultsController.tableView.dataSource = self
refreshController.attributedTitle = NSAttributedString(string: "")
refreshController.addTarget(self, action: #selector(refreshSelector), for: .valueChanged)
tableView.addSubview(refreshController)
searchController.searchBar.delegate = self
automaticallyAdjustsScrollViewInsets = false
definesPresentationContext = true
#objc func refreshSelector()
{
if(!searchLoaded)
{
searchLoaded = true
self.tableView.tableHeaderView = searchController.searchBar
self.navigationItem.rightBarButtonItem = nil
print( "Got ya")
}
refreshController.endRefreshing()
}
func configureSearchController ()
{
searchController = UISearchController(searchResultsController: resultsController)
searchController.searchResultsUpdater = self
searchController.searchBar.layer.borderWidth = 1;
searchController.searchBar.barTintColor = UIColor.searchBarBackgroundGrey()
searchController.searchBar.layer.borderColor = UIColor.searchBarBackgroundGrey().cgColor
self.navigationController?.navigationBar.shadowImage = UIImage()
}
deployment target has been set as 9.3
I have a strange issue which I don't really understand.
I have two views, one should have a black title and the other should have a white title.
The issue that I am experiencing is that I can set the color ONCE and not change it back.
So when I go to the view that has the white title from the view with the black title and then go back, the title does not change back to black.
code for white title in viewWillAppear:
self.navigationController?.navigationBar.barStyle = .black
self.navigationController?.navigationBar.tintColor = .white
self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
code for black title in viewWillAppear:
self.navigationController?.navigationBar.isHidden = false
self.navigationController?.navigationBar.barStyle = .default
self.navigationController?.navigationBar.tintColor = UIColor.blue
self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.black]
Why does it not change back, when I am clearly setting a new color?
EDIT: adding the complete code
Black title view:
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.navigationController?.navigationBar.isHidden = false
self.navigationController?.navigationBar.barStyle = .default
self.navigationController?.navigationBar.tintColor = hexStringToUIColor(hex: "4CAF50")
self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.black]
self.navigationItem.title = listData.name
clearStatusBarColor()
let editButton = UIBarButtonItem(title: "Edit", style: .plain, target: self, action: #selector(tapToEdit))
let sortImg = UIImage(named: "sort")
sortingButton = UIBarButtonItem(image: sortImg, style: .plain, target: self, action: #selector(tapToSort))
self.navigationItem.rightBarButtonItems = [sortingButton!, editButton]
self.navigationController?.navigationBar.setBackgroundImage(nil, for: UIBarMetrics.default)
self.navigationController?.navigationBar.shadowImage = nil
// get updated Data
if User.active.hasListUpdated {
// return with new gameEntries -> Update
listData = User.active.allLists![listDataIndex] // To keep upToDate data!
listEntries = listData.list_entries!
gameEntries = listEntries.compactMap({ (entry: ListEntry) -> GameEntry in
return GameEntry(game: entry.game, platform: nil, platform_id: entry.platform, rating: Int(entry.rating ?? 0), review: nil, notes: entry.description)
})
listTable.reloadData()
}
// Sorting
if hasSortChanged {
hasSortChanged = false
sortList(sort: sortingOption, order: sortingOrder)
}
}
White title view:
override func viewWillAppear(_ animated: Bool) {
if !isPreviewing {
self.navigationController?.navigationBar.isHidden = false
self.navigationController?.navigationBar.barStyle = .black
self.navigationController?.navigationBar.tintColor = .white
self.navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
// MARK: Clear StatusBar
clearStatusBarColor()
if transparentNav {
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for:UIBarMetrics.default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.title = nil
} else {
self.navigationController?.navigationBar.setBackgroundImage(nil, for: UIBarMetrics.default)
self.navigationController?.navigationBar.shadowImage = nil
self.title = game.name!
}
}
// MARK: NavigationBar
let button = UIBarButtonItem(barButtonSystemItem: .add, target: self, action: #selector(showOptions))
self.navigationItem.rightBarButtonItem = button
// Check if game should have new review or rating
if User.active.hasMainScreenUpdated {
// Update rating
updateUserRating()
// update review
updateUserReviewStatus()
}
// Update lists!
if User.active.hasListUpdated {
updateListsStatus()
}
}
If you are changing the nav bar colors in different view controllers, I recommend you to have a subclass of UIViewController and handle the navbar changes through that. Here's an example for your case.
class CustomUIViewController: UIViewController {
override func didMove(toParentViewController parent: UIViewController?) {
super.didMove(toParentViewController: parent)
if parent == nil {
if SettingsManager.LastBarColor == .default {
self.setLightBars()
}
else {
self.setDarkBars()
}
}
}
func setDarkBars() {
SettingsManager.LastBarColor = .lightContent
UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent
tabBarController?.tabBar.tintColor = UIColor.white
navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: UIColor.white]
}
func setLightBars() {
SettingsManager.LastBarColor = .default
UIApplication.shared.statusBarStyle = UIStatusBarStyle.default
tabBarController?.tabBar.tintColor = UIColor.Black
navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor:UIColor.Black]
navigationController?.navigationBar.barTintColor = UIColor.white
navigationItem.titleView?.tintColor = UIColor.Black
}
}
class SettingsManager {
class var LastBarColor: UIStatusBarStyle = .default
}
And in your view controller use CustomUIViewController, call setDarkBars() or setLightBars() in your viewWillAppear() function.
You can use a custom UINavigationController class then override pushViewController function to set what you need on the navigationBar.
The viewWillAppear method has a lot of code here.
class MyNavigationViewController: UINavigationController {
override func pushViewController(_ viewController: UIViewController, animated: Bool) {
super.pushViewController(viewController, animated: animated)
self.updateForVC(viewController: viewController)
}
func updateForVC(viewController: UIViewController) {
//DO WHATEVER YOU WHANT HERE, title, img, etc
var color = UIColor.black
if viewController.isKind(of: MyClass.self) {
color = UIColor.white
}
self.navigationBar.titleTextAttributes = [NSAttributedStringKey.foregroundColor: color]
}
}
Try pushViewController to navigate,It is working for me
if let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SecondViewController") as? SecondViewController {
if let navigator = self.navigationController {
navigator.pushViewController(viewController, animated: true)
viewController.title = ""
}
}
I'm having a weird problem, when my app first loads you cannot enter text in the search bar no matter how many times you tap it, the search bar is nested in the navigation bar.
My app also use a tab bar, and when you switch tabs then go back to the tab with the search bar it allows you enter text... any ideas what's causing this?
Heres the code for the searchBar:
func setupSearchBar(){
let locationSearchTable = storyboard!.instantiateViewController(withIdentifier: "LocationSearchTable") as! LocationSearchTableViewController
resultSearchController = UISearchController(searchResultsController: locationSearchTable)
resultSearchController?.searchResultsUpdater = locationSearchTable
searchBar = resultSearchController!.searchBar
searchBar.sizeToFit()
searchBar.placeholder = "Location"
searchBar.isTranslucent = true
searchBar.isUserInteractionEnabled = true
for subView in searchBar.subviews{
for subsubView in subView.subviews{
if let textField = subsubView as? UITextField{
var currentTextFieldBounds = textField.bounds
currentTextFieldBounds.size.height = 40.0
textField.bounds = currentTextFieldBounds
textField.borderStyle = UITextBorderStyle.none
textField.textAlignment = NSTextAlignment.left
textField.font = UIFont(name: "System", size: 25.0)
textField.textColor = theme?.textColour
}
}
}
self.navigationController?.navigationBar.setBarColour(colour: (theme?.tabBarColour)!, tint: (theme?.textColour)!)
navigationItem.titleView = resultSearchController?.searchBar
navigationItem.titleView?.bringSubview(toFront: (resultSearchController?.searchBar)!)
searchBar.delegate = self
searchBar.showsSearchResultsButton = true
searchBar.setImage(#imageLiteral(resourceName: "location_icon.png"), for: UISearchBarIcon.resultsList, state: UIControlState.normal)
resultSearchController?.hidesNavigationBarDuringPresentation = false
resultSearchController?.dimsBackgroundDuringPresentation = true
definesPresentationContext = true
locationSearchTable.mapView = mapView
locationSearchTable.handleMapSearchDelegate = self
}
Ok after a lot messing around, I discovered that in my custom UITabBarController I had used override func viewWillAppear(_ animated: Bool) without adding super.viewWillAppear() and that caused the problem! I assume because of that subviews weren't being laid out correctly. Hope that helps anyone who has a similar problem to mine.
I would like uisearchcontroller to start searching after I type at least three characters in search bar. So, what should I do for that ?
func configureSearchController() {
// Initialize and perform a minimum configuration to the search controller.
searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
searchController.searchBar.placeholder = "Search"
searchController.searchBar.delegate = self
searchController.searchBar.sizeToFit()
let textFieldInsideSearchBar = searchController.searchBar.valueForKey("searchField") as! UITextField
textFieldInsideSearchBar.font = UIFont(name: "Bauhaus", size: 19)
searchController.searchBar.setImage(UIImage(named: "searchikon"), forSearchBarIcon: UISearchBarIcon.Search, state: UIControlState.Normal);
// Place the search bar view to the tableview headerview.
TableView.tableHeaderView = searchController.searchBar
All you need to is add the single required method for the UISearchController.
func updateSearchResultsForSearchController(searchController: UISearchController) {
if searchController.searchBar.text?.characters.count > 2 {
// Filter your search results here
}
}
You will want to check the the length of the characters in an event which checks the change in the text field:
nameOfString.characters.count
