I need to display 4 UITextFields in an UIAlertController (Xcode 11.5). Did it as usual but the center UITextFields appear w/o border view image and it doesn't look well (I am adding a screenshot). I tried to set the UITextField Borderstyle, frame, but I can't get it right.
#IBAction func addButtonPressed(_ sender: UIBarButtonItem) {
var dayOfWeekField = UITextField()
var inicioTextField = UITextField()
var terminoTextField = UITextField()
var numeroDeCirugias = UITextField()
let alert = UIAlertController(title: "Agregar Nuevo Bloque", message: "", preferredStyle: .alert)
let action = UIAlertAction(title: "Agregar", style: .default) { (action) in
let nuevoBloque = Bloques(context: self.context)
nuevoBloque.dia = dayOfWeekField.text!
nuevoBloque.inicio = inicioTextField.text!
nuevoBloque.termino = terminoTextField.text!
nuevoBloque.cirugias = Int16(numeroDeCirugias.text!)!
self.bloques.append(nuevoBloque)
self.saveBloques()
}
alert.addAction(action)
alert.addAction(UIAlertAction(title: "Cancelar", style: .destructive, handler: nil))
alert.addTextField { (field) in
dayOfWeekField = field
dayOfWeekField.placeholder = "dia de la semana"
dayOfWeekField.autocapitalizationType = .none
}
alert.addTextField { (field2) in
inicioTextField = field2
inicioTextField.placeholder = "Inicio Bloque (HH:MM)"
inicioTextField.keyboardType = .numbersAndPunctuation
}
alert.addTextField { (field3) in
terminoTextField = field3
terminoTextField.placeholder = "Término Bloque (HH:MM)"
terminoTextField.keyboardType = .numbersAndPunctuation
}
alert.addTextField { (field4) in
numeroDeCirugias = field4
numeroDeCirugias.placeholder = "Número Cirugías"
numeroDeCirugias.keyboardType = .numberPad
}
present(alert, animated: true, completion: nil)
}[enter image description here][1]
Try this solution. I suggest to not capture references to the UITextfields, maybe that might have caused the behavior. You can Access them by UIAlertController.textFields property. Usually all layouting is done by the UIAlertController basically fine, I never encountered bugs there.
Also. try to avoid force unwrapping with ! by using guard let
#IBAction func addButtonPressed(_ sender: UIBarButtonItem) {
let alert = UIAlertController(title: "Agregar Nuevo Bloque", message: "", preferredStyle: .alert)
let action = UIAlertAction(title: "Agregar", style: .default) { (_) in
let nuevoBloque = Bloques(context: self.context)
guard
let dayOfWeek = alert.textFields?[0].text,
let inicio = alert.textFields?[1].text,
let temino = alert.textFields?[2].text,
let numeroDeCirugiasString = alert.textFields?[3].text,
let numeroDeCirugias = Int(numeroDeCirugiasString)
else {
// not all textfields were implemented or filled out properly
return
}
nuevoBloque.dia = dayOfWeek
nuevoBloque.inicio = inicio
nuevoBloque.termino = termino
nuevoBloque.cirugias = numeroDeCirugias
self.bloques.append(nuevoBloque)
self.saveBloques()
}
alert.addAction(action)
alert.addAction(UIAlertAction(title: "Cancelar", style: .cancel, handler: nil))
alert.addTextField { (field) in
field.placeholder = "dia de la semana"
field.autocapitalizationType = .none
}
alert.addTextField { (field2) in
field2.placeholder = "Inicio Bloque (HH:MM)"
field2.keyboardType = .numbersAndPunctuation
}
alert.addTextField { (field3) in
field3.placeholder = "Término Bloque (HH:MM)"
field3.keyboardType = .numbersAndPunctuation
}
alert.addTextField { (field4) in
field4.placeholder = "Número Cirugías"
field4.keyboardType = .numberPad
}
present(alert, animated: true, completion: nil)
}

I have created an alert Where a mybutton have to be hidden while the activity indicator has to be shown. but it didn't work.
Here is the code:
private func showAlert() {
let alert = UIAlertController(title: "aaaaaa", message: ccccccccc, preferredStyle: .alert)
let attributedString = NSAttributedString(string: "aaaaa", attributes: [.font: UIFont.boldSystemFont(ofSize: 18), //your font here
.foregroundColor : Theme.bleu!])
alert.setValue(attributedString, forKey: "attributedTitle")
alert.addAction(UIAlertAction(title: annuler, style: .cancel))
alert.addAction(UIAlertAction(title: optimiserLesMicrosUniquement, style: .default, handler: { (action) in
self.myButton.isHidden = true // Here begins the problem
self.activityIndicator.isHidden = false
let menuOptimiser = functionNumberX()
self.activityIndicator.isHidden = true // Here is the problem
self.myButton.isHidden = false
let reponse = menuOptimiser.0
if reponse == false {
self.showAlerteMenuOptimal()
} else {
if menuOptimiser.1 > 0 {
self.presentAlerteDuGain(gain: menuOptimiser.1, menu: menuOptimiser.2)
} else {
self.presentAlerteOptimisationSansGainDeCalories(calorie: abs((round(menuOptimiser.1))), menu: menuOptimiser.2)
}
}
self.gestionDeLaNotationDuMenuEnCours()
}))
present(alert, animated: true)
}
When i execute it, mybutton never disappears, and activity indicator never appears.
i don't know how to do that.
try removing, these two lines , since you are opposite at almost the same time .
self.activityIndicator.isHidden = true // Here is the problem
self.myButton.isHidden = false
I just found a solution. Here is the code
var menuOptimiser : (Bool, Float, [[AlimentObject]])!
private func showAlert() {
let alert = UIAlertController(title: "aaaaaa", message: ccccccccc, preferredStyle: .alert)
let attributedString = NSAttributedString(string: "aaaaa", attributes: [.font: UIFont.boldSystemFont(ofSize: 18), //your font here
.foregroundColor : Theme.bleu!])
alert.setValue(attributedString, forKey: "attributedTitle")
alert.addAction(UIAlertAction(title: annuler, style: .cancel))
alert.addAction(UIAlertAction(title: optimiserLesMicrosUniquement, style: .default, handler: { (action) in
self.myButton.isHidden = true // Here begins the problem
self.activityIndicator.isHidden = false
DispatchQueue.main.asyncAfter(deadline: .now()) {
let menuOptimiser = functionNumberX()
self.activityIndicator.isHidden = true // Here is the problem
self.myButton.isHidden = false
let reponse = menuOptimiser.0
if reponse == false {
self.showAlerteMenuOptimal()
} else {
if menuOptimiser.1 > 0 {
self.presentAlerteDuGain(gain: menuOptimiser.1, menu: menuOptimiser.2)
} else {
self.presentAlerteOptimisationSansGainDeCalories(calorie: abs((round(menuOptimiser.1))), menu: menuOptimiser.2)
}
}
}
self.gestionDeLaNotationDuMenuEnCours()
}))
present(alert, animated: true)
}
when i choose an option from action sheet, it set a title label to button. But when i click another button with another action sheet, it cancel title label of first button. How can i set each button without cancel any title label?
This is how it works:
This is my code of two action sheets:
#IBAction func paymentMethodActionSheet(_ sender: Any) {
PaymentMethodTitle.titleLabel?.text = "Seleziona"
let optionMenu = UIAlertController(title: nil, message: "Scegli il metodo di pagamento", preferredStyle: .actionSheet)
let cardAction = UIAlertAction(title: "Paga con carta", style: .default, handler: { action in
self.PaymentMethodTitle.titleLabel?.text = "Paga con carta"
self.PaymentMethodTitle.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let contantiAction = UIAlertAction(title: "Contanti", style: .default, handler: { action in
self.PaymentMethodTitle.titleLabel?.text = "Contanti"
self.PaymentMethodTitle.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let cancelAction = UIAlertAction(title: "Cancella", style: .cancel)
optionMenu.addAction(cardAction)
optionMenu.addAction(contantiAction)
optionMenu.addAction(cancelAction)
if let popoverController = optionMenu.popoverPresentationController {
popoverController.barButtonItem = sender as? UIBarButtonItem
popoverController.sourceView = self.view
popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController.permittedArrowDirections = []
}
self.present(optionMenu, animated: true, completion: nil)
}
#IBAction func shippingMethodActionSheet(_ sender: Any) {
shippingMethodTitle.titleLabel?.text = "Seleziona"
let option2Menu = UIAlertController(title: nil, message: "Scegli l'opzione d'acquisto", preferredStyle: .actionSheet)
let houseAction = UIAlertAction(title: "Consegna a domicilio", style: .default, handler: { action in
self.shippingMethodTitle.titleLabel?.text = "Consegna a domicilio"
self.shippingMethodTitle.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let businessAction = UIAlertAction(title: "Ritiro presso attività", style: .default, handler: { action in
self.shippingMethodTitle.titleLabel?.text = "Ritiro presso attività"
self.shippingMethodTitle.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let cancel2Action = UIAlertAction(title: "Cancella", style: .cancel)
option2Menu.addAction(houseAction)
option2Menu.addAction(businessAction)
option2Menu.addAction(cancel2Action)
if let popoverController2 = option2Menu.popoverPresentationController {
popoverController2.barButtonItem = sender as? UIBarButtonItem
popoverController2.sourceView = self.view
popoverController2.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController2.permittedArrowDirections = []
}
self.present(option2Menu, animated: true, completion: nil)
}
Instead of using self.PaymenMethodTitle?.titleLabel.text = "Contanti"to change the button title inside closure, just Use self.PaymentMethodTitle.setTitle("Contanti", for: .normal).
I've tried it myself and Its working Fine.
Code:
class ViewController: UIViewController {
#IBOutlet weak var btn1: UIButton!
#IBOutlet weak var btn2: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
#IBAction func btn1Pressed(_ sender: Any) {
let optionMenu = UIAlertController(title: nil, message: "Scegli il metodo di pagamento", preferredStyle: .actionSheet)
let cardAction = UIAlertAction(title: "Paga con carta", style: .default, handler: { action in
self.btn1.setTitle("Paga con carta", for: .normal)
self.btn1.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let contantiAction = UIAlertAction(title: "Contanti", style: .default, handler: { action in
self.btn1.setTitle("Conati", for: .normal)
self.btn1.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let cancelAction = UIAlertAction(title: "Cancella", style: .cancel)
optionMenu.addAction(cardAction)
optionMenu.addAction(contantiAction)
optionMenu.addAction(cancelAction)
if let popoverController = optionMenu.popoverPresentationController {
popoverController.barButtonItem = sender as? UIBarButtonItem
popoverController.sourceView = self.view
popoverController.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController.permittedArrowDirections = []
}
self.present(optionMenu, animated: true, completion: nil)
}
#IBAction func btn2Pressed(_ sender: Any) {
let option2Menu = UIAlertController(title: nil, message: "Scegli l'opzione d'acquisto", preferredStyle: .actionSheet)
let houseAction = UIAlertAction(title: "Consegna a domicilio", style: .default, handler: { action in
self.btn2.setTitle("Consegna a domicilio", for: .normal)
self.btn2.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let businessAction = UIAlertAction(title: "Ritiro presso attività", style: .default, handler: { action in
self.btn2.setTitle("Ritiro presso attività", for: .normal)
self.btn2.contentHorizontalAlignment = UIControl.ContentHorizontalAlignment.right
})
let cancel2Action = UIAlertAction(title: "Cancella", style: .cancel)
option2Menu.addAction(houseAction)
option2Menu.addAction(businessAction)
option2Menu.addAction(cancel2Action)
if let popoverController2 = option2Menu.popoverPresentationController {
popoverController2.barButtonItem = sender as? UIBarButtonItem
popoverController2.sourceView = self.view
popoverController2.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY, width: 0, height: 0)
popoverController2.permittedArrowDirections = []
}
self.present(option2Menu, animated: true, completion: nil)
}
}
Simulator ScreenShot:
I'm setting up 26 buttons, adding them as subviews to a letterButtonLabel, and appending them to an letterButtons array.
for row in 0..<6 {
for column in 0..<5 {
if row == 5 && column > 0 { continue }
let letterButton = UIButton(type: .system)
letterButton.titleLabel?.font = UIFont.systemFont(ofSize: 36)
letterButton.setTitle("O", for: .normal)
letterButton.addTarget(self, action: #selector(letterTapped), for: .touchUpInside)
let frame = CGRect(x: width * column, y: height * row, width: width, height: height)
letterButton.frame = frame
letterButtonLabel.addSubview(letterButton)
letterButtons.append(letterButton)
}
}
Afterwards, I assign a letter to each button using the letterButtons array.
var index = 0
for letter in "ABCDEFGHIJKLMNOPQRSTUVWXYZ" {
letterButtons[index].setTitle("\(letter)", for: .normal)
index += 1
}
I then manually add layout constraints.
Here is the functionality for each button:
#objc func letterTapped(_ sender: UIButton) {
// check the letter and react
sender.isHidden = true
guard let word = currentWord else { return }
guard var charactersArray = currentWordField.text?.components(separatedBy: "") else { return }
guard let originalCurrentWordField = currentWordField.text else { return }
for (index, letter) in word.enumerated() {
let strLetter = String(letter)
if strLetter == sender.titleLabel?.text {
charactersArray[index] = strLetter
}
}
currentWordField.text = charactersArray.joined()
if currentWordField.text == originalCurrentWordField {
livesLeft -= 1
}
if wordBank.contains(word) {
// you got it! reset letters
level += 1
let ac = UIAlertController(title: "Good job!", message: nil, preferredStyle: .alert)
let action = UIAlertAction(title: "Continue", style: .default, handler: resetForNextLevel)
ac.addAction(action)
present(ac, animated: true)
}
if livesLeft == 0 {
let ac = UIAlertController(title: "Game Over", message: nil, preferredStyle: .alert)
let action = UIAlertAction(title: "Restart", style: .default, handler: resetForNextLevel)
ac.addAction(action)
present(ac, animated: true)
}
}
(adding all just in case)
My button doesn't highlight or click. Is there anything here that might explain the problem? I'm curious about common mistakes.
UILabel has by default userInteractionEnabled = false.
Setting this to true should fix your problem
I have a UIAlertController with two textFields :
class ModifiedSearchViewController: UISearchController, UISearchBarDelegate {
var nameOfOwnPlace = ""
var adressOfOwnPlace = ""
func insertYourPLace() {
let alertController = UIAlertController(title: "Insert New Place", message: "", preferredStyle: UIAlertControllerStyle.Alert)
let saveAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: {
alert -> Void in
let nameTextField = alertController.textFields![0] as UITextField
let adressTextField = alertController.textFields![1] as UITextField
self.nameOfOwnPlace = nameTextField.text!
self.adressOfOwnPlace = adressTextField.text!
print(self.nameOfOwnPlace)
})
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Default, handler: {
(action : UIAlertAction!) -> Void in
})
alertController.addTextFieldWithConfigurationHandler { (textField : UITextField!) -> Void in
textField.placeholder = "Enter Place's Name..."
}
alertController.addTextFieldWithConfigurationHandler { (textField : UITextField!) -> Void in
textField.placeholder = "Enter Adress's Name..."
}
alertController.addAction(saveAction)
alertController.addAction(cancelAction)
self.presentViewController(alertController, animated: true, completion: nil)
}
...
}
I have an other view using my ModifiedSearchViewController class
but I dont succeed to send my strings (nameOfOwnPlace, adressOfOwnPlace) to the other view
searchController = ModifiedSearchViewController(searchResultsController: resultsViewController)
print(searchController.adressOfOwnPlace) // nil
Thanks for any help! :)
EDIT::
var resultsViewController = GMSAutocompleteResultsViewController()
var searchController = ModifiedSearchViewController()
func setSearchViewController() {
resultsViewController.delegate = self
searchController = ModifiedSearchViewController(searchResultsController: resultsViewController)
searchController.searchResultsUpdater = resultsViewController
print(searchController.adressOfOwnPlace) // nil
}
In my collection view cell, I have a button which successfully saves the current user (PFUser) to an array of users of each event (which are the objects at index path).
However, I would like to add an alert view, but have been unsuccessful in putting the enormous chunk of code inside the alert action block. I suppose I could create another method but I feel there's a simpler way to do it.
When I tried putting it in, A. the sheer number of brackets threw me off a bit and B. it didn't recognize "alertController" anymore at the bottom of the method.
Thanks for the help like always.
func buttonTapped(sender: AnyObject) {
let button = sender as! UIButton
let view = button.superview
let cell = view?.superview as! EventCell
let indexPath = collectionView.indexPathForCell(cell)
// print(indexPath)

if let event = events?[indexPath.row] {
//pops alert vc
var alertController : UIAlertController = UIAlertController(title: event.eventTitle, message: nil, preferredStyle: UIAlertControllerStyle.Alert)
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
alertController.addAction(cancelAction)
let saveUserToEvent = UIAlertAction(title: "Yes", style: .Default) { _ in
// WHAT TO DO HERE? I want to add the stuff below
}
alertController.addAction(saveUserToEvent)
var attendees = [String]()
if let attendeesTmp = event["attendees"] as?[String] {
attendees = attendeesTmp;
}
if let objId = PFUser.currentUser()?.objectId {
var found = false

Did you put
alertController.addAction(saveUserToEvent)
In the brackets as well? It stays outside.
This should work
func buttonTapped(sender: AnyObject) {
let button = sender as! UIButton

//pops alert vc

let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
alertController.addAction(cancelAction)
let saveUserToEvent = UIAlertAction(title: "Yes", style: .Default) { _ in
var attendees = [String]()
if let attendeesTmp = event["attendees"] as?[String] {
attendees = attendeesTmp;
}
if let objId = PFUser.currentUser()?.objectId {
var found = false
for objIdd in attendees {
if objIdd == objId {
found = true
break;
}
}
if !found {
attendees.append(objId)
event["attendees"] = attendees;
event.saveInBackground()
}
}
if let user = PFUser.currentUser() {
var eventsAttending = [String]()
if let eventsAttendingTmp = user["eventsToAttend"] as?[String] {
eventsAttending = eventsAttendingTmp;
}
if let eventId = event.objectId {
var found = false
for eventIdd in eventsAttending {
if eventIdd == eventId {
found = true
break;
}
}
if !found {
eventsAttending.append(eventId)
user["eventsToAttend"] = eventsAttending;
user.saveInBackground()
}
}
}
}
alertController.addAction(saveUserToEvent)
}
}
}
