I want to close my uidatepicker and my toolbar by pressing a "done"-button in my toolbar.
I am using a label instead of a textfield so the common solutions don't work.
I have tried:
#IBAction func ButtonPressed(_ sender: UIButton) {
print("hallo")
let picker = UIDatePicker()
picker.backgroundColor = .white
picker.datePickerMode = .date
//picker.sizeToFit()
var datumComponents = DateComponents()
datumComponents.year = 2019
datumComponents.month = 6
datumComponents.day = 1
let meinStartKalender = Calendar.current
let StartDatum = meinStartKalender.date(from: datumComponents)
picker.minimumDate = StartDatum
picker.maximumDate = Date()
let pickerSize1 = myView.bounds.width
picker.addTarget(self, action: #selector(dueDateChanged(sender:)), for: UIControl.Event.valueChanged)
picker.frame = CGRect(x:0.0, y: self.view.frame.height - 300 , width: pickerSize1, height: 200)
self.view.addSubview(picker)
let toolBar = UIToolbar()
toolBar.barStyle = UIBarStyle.default
toolBar.backgroundColor = .red
toolBar.frame = CGRect(x:0.0, y: self.view.frame.height - 340 , width: pickerSize1, height: 40)
self.view.addSubview(toolBar)
what I've found already:
add:
let doneButton = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(self.donePressed(_:)))
toolBar.setItems([doneButton], animated: false)
but the error message says:
Value of type 'ViewController' has no member 'donePressed'
how can I change the action or how can I implement a button that works?
Add this in your code
#objc
func donePressed(_ sender: UIButton) {
}

Screenshot of the gap
I need to present a popover view from a UIBarbuttonItem in a UIToolbar. But there exists a gap between the popover view and the toolbar.
private func addToolbar() {
let toolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 50))
let item1 = UIBarButtonItem(image: UIImage(systemName: "pencil"), style: .plain, target: self, action: #selector(item1Pressed(_:)))
let item2 = UIBarButtonItem(image: UIImage(systemName: "house"), style: .plain, target: self, action: #selector(item2Pressed(_:)))
toolBar.sizeToFit()
toolBar.items = [item1, item2]
textField.inputAccessoryView = toolBar
}
class SearchViewController: UIViewController {
let searchBar = UISearchBar()
weak var viewControllerDelegate: SearchViewControllerDelegate?
override func viewDidLoad() {
super.viewDidLoad()
setupView()
setupSearchbar()
}
private func setupView() {
view.backgroundColor = .white
navigationController?.navigationBar.prefersLargeTitles = true
self.title = "Search"
}
private func setupSearchbar() {
searchBar.sizeToFit()
searchBar.placeholder = "Search test"
searchBar.showsCancelButton = true
searchBar.delegate = self
self.navigationItem.titleView = searchBar
}
}
I tried setting the sourceRect of the presented popover view, but the popover view doesn't move down below a certain point.
#objc private func item1Pressed(_ sender: UIBarButtonItem) {
let vc = SearchViewController()
vc.viewControllerDelegate = self
let navVC = UINavigationController(rootViewController: vc)
navVC.modalPresentationStyle = .popover
navVC.popoverPresentationController?.delegate = self
navVC.popoverPresentationController?.permittedArrowDirections = .any
navVC.preferredContentSize = CGSize(width: 500, height: 200)
navVC.popoverPresentationController?.sourceItem = sender
var location = CGPoint(x: 0, y: 0)
if let barItemView = sender.value(forKey: "view") as? UIView {
let barFrame = barItemView.frame
let rect = barItemView.convert(barFrame, to: view)
location = rect.origin
}
navVC.popoverPresentationController?.sourceRect = CGRect(x: location.x, y: location.y+100, width: 0, height: 0)
present(navVC, animated: true)
}
I have an UIToolbar containing a UITextField. I want to show the toolbar above the keyboard and then display it again when I finish editing inside the textfield.
The issue is that it is working when selecting the textfield. However, the toolbar is disappearing from the view when hiding the keyboard.
What should be done to redisplay it again to my view?
My Swift code is:
Add UITextFieldDelegate
class ATCChatThreadViewController: MessagesViewController, MessagesDataSource, MessageInputBarDelegate, UITextFieldDelegate {
Create ToolBar is as below
func createToolbar(){
//Fixed space
let fixed = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.fixedSpace, target: self, action: nil)
fixed.width = 10
//Camera
//let img = UIImage(named: "camera-filled-icon")!.withRenderingMode(UIImage.RenderingMode.alwaysOriginal)
let img = UIImage.localImage("camera-filled-icon", template: true)
let iconSize = CGRect(origin: CGPoint.zero, size: CGSize(width: 30, height: 30))
let iconButton = UIButton(frame: iconSize)
iconButton.setTitleColor(uiConfig.primaryColor, for: .normal)
iconButton.setBackgroundImage(img, for: .normal)
let cameraItem = UIBarButtonItem(customView: iconButton)
cameraItem.tintColor = uiConfig.primaryColor
iconButton.addTarget(self, action: #selector(cameraButtonPressed), for: .touchUpInside)
//TextField true
textFieldChat = UITextField(frame: CGRectMake(0,0,(self.view.frame.size.width - 100) ,30))
textFieldChat.tintColor = uiConfig.primaryColor
textFieldChat.textColor = uiConfig.inputTextViewTextColor
textFieldChat.backgroundColor = uiConfig.inputTextViewBgColor
textFieldChat.layer.cornerRadius = 14.0
textFieldChat.layer.borderWidth = 0.0
textFieldChat.font = UIFont.systemFont(ofSize: 16.0)
textFieldChat.delegate = self
textFieldChat.attributedPlaceholder = NSAttributedString(string: "Start typing...".localized(), attributes: [NSAttributedString.Key.foregroundColor: uiConfig.inputPlaceholderTextColor])
let paddingView: UIView = UIView(frame: CGRect(x: 0, y: 0, width: 10, height: 20))
textFieldChat.leftView = paddingView
textFieldChat.leftViewMode = .always
let textFieldButton = UIBarButtonItem(customView: textFieldChat)
//Fixed space
let fixedTwo = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.fixedSpace, target: self, action: nil)
fixedTwo.width = 10
//Send Button
let imgSend = UIImage.localImage("share-icon", template: true)
let iconSendSize = CGRect(origin: CGPoint.zero, size: CGSize(width: 30, height: 30))
let sendButton = UIButton(frame: iconSendSize)
sendButton.setTitleColor(uiConfig.primaryColor, for: .normal)
sendButton.setBackgroundImage(imgSend, for: .normal)
let sendItem = UIBarButtonItem(customView: sendButton)
sendItem
.tintColor = uiConfig.primaryColor
sendButton.addTarget(self, action: #selector(sendBtnPressedWith), for: .touchUpInside)
//Flexible Space
// let flexible = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.flexibleSpace, target: self, action: nil)
let flexible = UIBarButtonItem(barButtonSystemItem: UIBarButtonItem.SystemItem.fixedSpace, target: self, action: nil)
flexible.width = 10
//Toolbar
var bottomsafeAreaHeight: CGFloat?
if #available(iOS 11.0, *) {
bottomsafeAreaHeight = UIApplication.shared.windows.first{$0.isKeyWindow }?.safeAreaInsets.bottom ?? 0
} else {
// Fallback on earlier versions
bottomsafeAreaHeight = bottomLayoutGuide.length
bottomsafeAreaHeight = UIApplication.shared.keyWindow?.rootViewController?.bottomLayoutGuide.length ?? 0
}
toolbar = UIToolbar(frame: CGRectMake(0,(self.view.frame.size.height - 116 - (bottomsafeAreaHeight ?? 0)),view.frame.width,50))
toolbar.sizeToFit()
toolbar.barTintColor = UIColor.f5f5f5ColorBg()
toolbar.isTranslucent = false
toolbar.tintColor = uiConfig.primaryColor
toolbar.items = [fixed, cameraItem, fixed, textFieldButton,fixedTwo, sendItem,flexible]
view.addSubview(toolbar)
}
// MARK: - UITextFieldDelegate
func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
textFieldChat.inputAccessoryView = toolbar
return true
}
func textFieldShouldEndEditing(_ textField: UITextField) -> Bool {
view.addSubview(toolbar)
self.toolbar.isHidden = false
return true
}
if only chat etxfield is using toolbar then replace line:
view.addSubview(toolbar)
with
textFieldChat.inputAccessoryView = toolbar
remove both methods textFieldShouldBeginEditing and textFieldShouldEndEditing
I create UITextView with a random tag and text, but it is created with one variable, is it possible to update the variable after creation UITextView (by clicking the add button)? Maybe add a random number to it, for example newText1, newText2.. etc.
So that the next UITextView is already created with a new variable?
P.S Sorry, if the question is silly, I just recently started to study Swift
#IBOutlet weak var addTextButton: UIButton!
#IBOutlet weak var StoriesView: UIView!
var newText = UITextView()
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func addTextButton(_ sender: Any) {
let maxNumber = 10000
let i = Int(arc4random_uniform(UInt32(maxNumber)))
newText = UITextView(frame: CGRect(x: self.StoriesView.frame.origin.x + 40, y: self.StoriesView.frame.origin.y + 40, width: 380, height: 80))
self.StoriesView.addSubview(newText)
newText.font = UIFont(name: "Verdana", size: 11)
newText.text = "TAP TO EDIT #\(i)"
newText.sizeToFit()
newText.textColor = UIColor.black
newText.backgroundColor = UIColor.clear
newText.tag = i
newText.isEditable = true
newText.isSelectable = true
newText.isUserInteractionEnabled = true
newText.allowsEditingTextAttributes = true
newText.translatesAutoresizingMaskIntoConstraints = true
newText.enablesReturnKeyAutomatically = true
newText.delegate = self
}
UPD:
let fontToolbar = UIToolbar(frame:CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
fontToolbar.barStyle = .default
fontToolbar.items = [
UIBarButtonItem(title: "Green", style: .plain, target: self, action: #selector(greenColor)),
UIBarButtonItem(title: "Blue", style: .plain, target: self, action: #selector(blueColor)),
UIBarButtonItem(title: "Red", style: .plain, target: self, action: #selector(redColor)),
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil),
UIBarButtonItem(title: "Close Keyboard", style: .plain, target: self, action: #selector(dismissKeyboard))]
fontToolbar.sizeToFit()
newText.inputAccessoryView = fontToolbar
in the toolBar above the keyboard I have buttons, here we change the color
#objc func redColor() {
newText.textColor = UIColor.red}
#objc func blueColor() {
newText.textColor = UIColor.blue}
#objc func greenColor() {
newText.textColor = UIColor.green}
So the color changes only in the newly created UITextView
On click of button, create a new texView and assign it a tag value. Once it is added, update the value of i to +1, so that every textView added has a new tag value.
var i = 1
var newText = UITextView()
#IBAction func addTextButton(_ sender: Any) {
newText = UITextView(frame: CGRect(x: self.StoriesView.frame.origin.x + 40, y: self.StoriesView.frame.origin.y + 40, width: 380, height: 80))
self.StoriesView.addSubview(newText)
newText.font = UIFont(name: "Verdana", size: 11)
newText.text = "TAP TO EDIT #\(i)"
newText.sizeToFit()
newText.textColor = UIColor.black
newText.backgroundColor = UIColor.clear
newText.tag = i
newText.isEditable = true
newText.isSelectable = true
newText.isUserInteractionEnabled = true
newText.allowsEditingTextAttributes = true
newText.translatesAutoresizingMaskIntoConstraints = true
newText.enablesReturnKeyAutomatically = true
newText.delegate = self
//increment i
i+=1
}
then you can access your textField via tag values like this:
if let textView = self.StoriesView.viewWithTag(i) as? UITextView {
// textView.text = "change it"
}
UPDATE:
Add textView Delegate method, and once a textView starts editing, change the newText value to the currently editing textView
class ViewController : UIViewController, UITextViewDelegate {
func textViewDidBeginEditing(_ textView: UITextView) {
newText = textView
}
}
I have modified your code a bit to have new UITextView object with button click
import UIKit
class ScannerViewController: UIViewController, UITextViewDelegate {
#IBOutlet weak var StoriesView: UIView!
#IBOutlet weak var addTextButton: UIButton!
var yposition: CGFloat!
var textFieldTag: [Int]! = []
override func viewDidLoad() {
super.viewDidLoad()
yposition = 20
}
#IBAction func addTextButton(_ sender: Any) {
let xposition = self.StoriesView.frame.origin.x
let maxNumber = 10000
let i = Int(arc4random_uniform(UInt32(maxNumber)))
textFieldTag.append(i)
let newText = UITextView(frame: CGRect(x: xposition , y: yposition , width: 380, height: 40))
self.StoriesView.addSubview(newText)
newText.font = UIFont(name: "Verdana", size: 11)
newText.text = "TAP TO EDIT #\(i)"
newText.sizeToFit()
newText.textColor = UIColor.black
newText.backgroundColor = UIColor.yellow
newText.tag = i
newText.isEditable = true
newText.isSelectable = true
newText.isUserInteractionEnabled = true
newText.allowsEditingTextAttributes = true
newText.translatesAutoresizingMaskIntoConstraints = true
newText.enablesReturnKeyAutomatically = true
newText.delegate = self
yposition = yposition + 45
}
#IBAction func accessTextFields(_ sender: Any) {
//access all text fields
for tag in textFieldTag {
if let textField = self.StoriesView.viewWithTag(tag) as? UITextView {
//change properties here
textField.backgroundColor = .cyan
}
}
//access specific text fields
if let textField = self.StoriesView.viewWithTag(textFieldTag.first!) as? UITextView {
//change properties here
textField.backgroundColor = .orange
}
if let textField = self.StoriesView.viewWithTag(textFieldTag[textFieldTag.count - 1]) as? UITextView {
//change properties here
textField.backgroundColor = .green
}
}
}
It will have an output as this!!
I'm trying trying to change my toolbar that I added Programmatically. but it didn't reflect. so any help
this is my code. and in the viewController I embed the view from UINavigation Controller
class ViewController: UIViewController,UIToolbarDelegate {
private var toolItems : [UIBarButtonItem] = []
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
navigationController?.isToolbarHidden = false
let height: CGFloat = 130
let bounds = self.navigationController?.toolbar.bounds
navigationController?.toolbar.barTintColor = UIColor(red: 0.0/42, green: 0.0/42, blue: 0.0/56, alpha: 1)
navigationController?.toolbar.tintColor = UIColor.white
navigationController?.toolbar.frame = CGRect(x: 0, y: self.view.frame.height - 80, width: self.view.frame.width, height: (bounds?.height)! + height)
navigationController?.toolbar.isTranslucent = false
navigationController?.toolbar.heightAnchor.constraint(equalToConstant: (bounds?.height)! + height).isActive = true
navigationController?.toolbar.sizeToFit()
let btn_Tracking = UIButton(type: .custom)
btn_Tracking.setImage(UIImage(named: "icon-trackingtabbed#2x"), for: .normal)
btn_Tracking.sizeToFit()
let trackingItem = UIBarButtonItem(customView: btn_Tracking)
///Sign
let btn_sign = UIButton(type: .custom)
btn_sign.setImage(UIImage(named: "icon-trackingtabbed#2x"), for: .normal)
btn_sign.sizeToFit()
let sginItem = UIBarButtonItem(customView: btn_sign)
let fixedSpace: UIBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.fixedSpace, target: nil, action: nil)
fixedSpace.width = 10.0
let flexibleSpace: UIBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
self.toolbarItems = [flexibleSpace,sginItem,flexibleSpace,trackingItem,flexibleSpace]
}
}
I have got a textfield in my Swift code
let PassINP: UITextField = {
let textField = UITextField()
textField.rightViewMode = .always
var imageR = UIImageView(frame: CGRect(x:7,y:4,width:24,height:27))
imageR.image = #imageLiteral(resourceName: "eye")
var paddingR = UIView(frame: CGRect(x: 0, y: 0, width:40, height: 32))
paddingR.addSubview(imageR)
textField.rightView = paddingR
textField.isSecureTextEntry = true
return textField
}()
And i want to call a function when rightView is clicked.How can i achieve that?
I have tried adding this code
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ViewController.rightViewTapped))
paddingR.addGestureRecognizer(tapGesture)
But it was not working
For that you need to add TapGesture to rightView of your UITextField.
//Add UITapGestureRecognizer to your PassINP's rightView `viewDidLoad`
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(favoriteButtonPressed))
PassINP.rightView?.addGestureRecognizer(tapGesture)
Now add rightViewTapped method to handle the tap on the rightView
func rightViewTapped(_ gesture: UITapGestureRecognizer) {
print("rightViewTapped")
}
