My code for search bar delegate is:
extension ViewController: UISearchBarDelegate{
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
// change the array that is being printed
searching = true
print("here")
tableView.reloadData()
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searching = false
searchBar.text = ""
print("cancel")
tableView.reloadData()
}
}
My search bar is connected as #IBOutlet weak var searchBar: UISearchBar!
Setting aside whether I'm filtering things right, right now neither typing into the search bar nor clicking cancel does anything (as shown above, at least when those methods get called "here" and "cancel" should be printed to the console), and cancel is not clearing the search bar text either. Does anyone know why this happens/what I did wrong?
Have you checked if you set the searchBar delegate as the ViewController? You've done right implementing the protocol, but make sure you have this code in your viewDidLoad function:
self.searchBar.delegate = self
Is also worth checking if the storyboard search bar element is really connected to the #IBOutlet declared on the ViewController. You can find this in the connections inspector. Yours must look like this:
Look at the second connection in this image
I want to just hide keyboard when user first press cancel button.
Just likes AppStore.app
I use UISearchController like that:
navigationItem.searchController = searchController
============== Update ==============
This Cancel button is hosted by UISearchController.
If you did search bar programmatically, you can add extension on your ViewController or else just use function call as below.
extension ViewController: UISearchBarDelegate {
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
if let text = searchBar.text {
self.filterContent(text: text)
searchBar.resignFirstResponder()
}
}
}
I try to make my searchbar on swift, but I have a problem to dismiss keyboard on screen when I pressed out of searchbar. When I try with textfield, it works perfectly fine with this code.
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
self.view.endEditing(true)
}
It work when i press out of my textfield and then the keyboard is gone. I want to make like that with my searchbar, because when I use searchbar and use the same way like textfield, it doesn't work at all. Any reference or code is very useful for me.
try this :
self.mySearchController.searchBar.endEditing(true)
replace mySearchController with your created controller name..
If you did not create it programmatically but instead you just dragged a search bar from library then IBoutlet your searchable to your class and reference it as:
self.mySearchBar.endEditing(true)
I found it easier and simplier to use Table View for dismissal. (If you're using table view)
Swift 4:
self.tableView.keyboardDismissMode = .onDrag
Tested and working!
func searchBarSearchButtonClicked(searchBar: UISearchBar)
{
searchActive = false;
self.mySearchBar.endEditing(true)
}
Edit for Swift 4.2
func searchBarSearchButtonClicked(_ searchBar: UISearchBar)
{
searchActive = false
self.searchBar.endEditing(true)
}
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
searchActive = false;
searchProject.resignFirstResponder()
}
This method will be invoked when user click search button on keyboard.So here we can dismiss keyboard.I think this is the right method.
Firstly, Apple's UISearchBarDelegate is the correct solution to hide keyboard when users click a search button while UISearchBar's instance is the first responder (learn UIResponder). In short, searchBarSearchButtonClicked(_:) is what you need for this task.
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
searchBar.resignFirstResponder() // hides the keyboard.
doThingsForSearching()
}
If it doesn't work, check, does your controller conform to UISearchBarDelegate and secondly, does UISearchBarDelegate know about your class implementation (if you don't quite understand what am I talking about, you should learn delegation pattern starting to read here):
class YourAwesomeViewController: UIViewController, UISearchBarDelegate { // pay attention here
#IBOutlet weak var yourSearchBar: UISearchBar!
override func viewDidLoad() {
super.viewDidLoad()
self.yourSearchBar.delegate = self // and it's important too
}
}
Further, if you need to hide the keyboard touching outside of search bar without touching the search button (the user may change his mind to search something), UITapGestureRecognizer is a simple way too to deal with that.
Ctrl-drag a Tap Gesture Recognizer from the Object Library to your View Controller.
Ctrl-drag the recently added Tap Gesture Recognizer from the document outline in the storyboard to your class implementation as IBAction.
Finally, write a code:
#IBAction func tapToHideKeyboard(_ sender: UITapGestureRecognizer) {
self.yourSearchBar.resignFirstResponder()
}
Also, don't forget to create #IBOutlet for the search bar to have an access inside your class implementation.
Both variants above work well in my project.
Swift 4+:
You can try, creating a tap gesture and add in the self.view
let singleTapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.singleTap(sender:)))
singleTapGestureRecognizer.numberOfTapsRequired = 1
singleTapGestureRecognizer.isEnabled = true
singleTapGestureRecognizer.cancelsTouchesInView = false
self.view.addGestureRecognizer(singleTapGestureRecognizer)
and in selector func you call self.searchBar.resignFirstResponder
#objc func singleTap(sender: UITapGestureRecognizer) {
self.searchBar.resignFirstResponder()
}
You can use a general UIViewController extension
Just add a new swift file on the project and paste the following code snippet
Code
extension UIViewController {
func hideKeyboardWhenTappedAround() {
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissKeyboard(_:)))
tap.cancelsTouchesInView = false
view.addGestureRecognizer(tap)
}
#objc func dismissKeyboard(_ sender: UITapGestureRecognizer) {
view.endEditing(true)
if let nav = self.navigationController {
nav.view.endEditing(true)
}
}
}
Now call hideKeyboardWhenTappedAround() from viewDidLoad method where you want keyboard hiding feature.
class MaCaveViewController: UIViewController, UISearchBarDelegate {
#IBOutlet weak var searchBar: UISearchBar!
override func viewDidLoad() {
super.viewDidLoad()
searchBar.delegate = self
}
// When button "Search" pressed
func searchBarSearchButtonClicked(_ searchBar: UISearchBar){
print("end searching --> Close Keyboard")
self.searchBar.endEditing(true)
}
}
This works very well for me.
we can do this with following methods
func searchBarTextDidBeginEditing(searchBar: UISearchBar) {
searchBar.showsCancelButton = true;
}
func searchBarTextDidEndEditing(searchBar: UISearchBar) {
searchBar.showsCancelButton = false;
}
This works for me in Swift 4
func searchBarSearchButtonClicked(_ searchBar: UISearchBar){
self.searchBar.endEditing(true)
}
I have an action to call searchBar. When it is called, i want the keyboard to show up.
How can i show the keyboard?
This is the code with my action:
#IBAction func Searappear(sender: AnyObject) {
searchBar.hidden=false
navigationController?.navigationBarHidden = true
}
You should call searchBar.becomeFirstResponder().
I am having trouble dismissing the keyboard of a text view in swift.
I was able to dismiss a textfield with the following
#IBAction func DismissKeyboard(sender: AnyObject)
{
self.resignFirstResponder()
}
But I'm not sure how I go about it with a text view
You have to set the textview.delegate to self and use the shouldChangeTextInRange function to resign on pressing return.
func textView(textView: UITextView, shouldChangeTextInRange range: NSRange, replacementText text: String) -> Bool {
if text == "\n" // Recognizes enter key in keyboard
{
textView.resignFirstResponder()
return false
}
return true
}
swift 3
func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
if text == "\n" {
textView.resignFirstResponder()
return false
}
return true
}
just add the UITextView as an IBOutlet and use the same function:
#IBAction func DismissKeyboard(sender: AnyObject) {
yourtextView.resignFirstResponder()
}
This is a much better more-intuitive (for your user) solution for dismissing soft keyboard. The problem with the "\n" solution is the user cannot insert line-breaks in the textView-- as hitting the return/done button on the keyboard will dismiss the keyboard before the line break occurs. The method below lets you keep that functionality while teaching the user that just tapping outside text-entry fields is a standard way of dismissing keyboards.
// MARK: - dismiss keyboard when user taps outside of text boxes
override func viewDidLoad() {
super.viewDidLoad()
configureTapGesture()
}
private func configureTapGesture() {
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(WriteJournalEntryViewController.handleTap))
view.addGestureRecognizer(tapGesture)
}
#objc func handleTap() {
view.endEditing(true)
}
(assumes this code is inside a UIViewController custom subclass named "WriteJournalEntryViewController).
view = your entire view in the UIViewController, so it works for more than just your textView object.
endEditing = a method for UIView class, you can read its documentation.
