I am working on project. i have added a simple alertController on clicking signup button. when i click on the button my viewcontroller reloads and then it shows that alertController. It is happening on iOS 13 and swift 5 or above
let alert = UIAlertController(title: "Your title", message: "Your message", preferredStyle: .alert)
let ok = UIAlertAction(title: "OK", style: .default, handler: { action in
})
alert.addAction(ok)
let cancel = UIAlertAction(title: "Cancel", style: .default, handler: { action in
})
alert.addAction(cancel)
DispatchQueue.main.async(execute: {
self.present(alert, animated: true)
})
i resolved my problem by these lines of code
func alert(message: String, title: String = "") {
let alertController = UIAlertController(title: title, message: message, preferredStyle: .alert)
let alertAction = UIAlertAction(title: "OK", style: .default) { (action) in
print("Action")
}
alertController.addAction(alertAction)
(UIApplication.shared.delegate as! AppDelegate).alertWindow.isHidden = true
self.presentViewController(alertController: alertController)
// self.present(alertController, animated: true, completion: nil)
}
func presentViewController(alertController: UIAlertController, completion: (() -> Void)? = nil) {
if var topController = UIApplication.shared.keyWindow?.rootViewController {
while let presentedViewController = topController.presentedViewController {
topController = presentedViewController
}
DispatchQueue.main.async {
topController.present(alertController, animated: true, completion: completion)
}
}
}
I have see more so answers , but nothing helped.Here is my older alert and action for that
override func viewWillAppear(animated: Bool) {
if Reachability.isConnectedToNetwork() == true {
print("internet connection ok")
} else
{
print("internet not ok")
let alertView: UIAlertView = UIAlertView(title: "Alert ", message: "connect to internet", delegate: self, cancelButtonTitle: "settings", otherButtonTitles: "cancel")
alertView.show()
return
}
}
func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int)
{
if buttonIndex == 0 {
//This will open ios devices wifi settings
UIApplication.sharedApplication().openURL(NSURL(string: "prefs:root")!)
}
else if buttonIndex == 1
{
//TODO for cancel
exit(0)
}
}
In that i am getting warning :
'UIAlertView' was deprecated in iOS 9.0. Use UIAlertController with a
preferredStyle of UIAlertControllerStyleAlert instead
I tried :
let alert = UIAlertController(title: "Alert", message: "My Alert for test", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil))
alert.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Default, handler: { (action:UIAlertAction!) in
print("you have pressed the Cancel button")
}))
self.presentViewController(alert, animated: true, completion: nil)
But to add two button and add the index path of button press method link my older code,I am not able to do that. Nothing action happening fro my uialert button,
Please help me out,How can i remove that warnings and recode my Uialert with my two button action.
I am new to swift.Your help will be useful.Thanks!
See this Code Destructive and OK buttons in UIAlertController:
let alertController = UIAlertController(title: "Destructive", message: "Simple alertView demo with Destructive and Ok.", preferredStyle: UIAlertControllerStyle.alert) //Replace UIAlertControllerStyle.Alert by UIAlertControllerStyle.alert
let DestructiveAction = UIAlertAction(title: "Destructive", style: UIAlertActionStyle.Destructive) {
(result : UIAlertAction) -> Void in
print("Destructive")
}
// Replace UIAlertActionStyle.Default by UIAlertActionStyle.default
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
(result : UIAlertAction) -> Void in
print("OK")
}
alertController.addAction(DestructiveAction)
alertController.addAction(okAction)
self.presentViewController(alertController, animated: true, completion: nil)
Swift 3:
let alertController = UIAlertController(title: "Destructive", message: "Simple alertView demo with Destructive and Ok.", preferredStyle: UIAlertControllerStyle.alert) //Replace UIAlertControllerStyle.Alert by UIAlertControllerStyle.alert
let DestructiveAction = UIAlertAction(title: "Destructive", style: UIAlertActionStyle.destructive) {
(result : UIAlertAction) -> Void in
print("Destructive")
}
// Replace UIAlertActionStyle.Default by UIAlertActionStyle.default
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
(result : UIAlertAction) -> Void in
print("OK")
}
alertController.addAction(DestructiveAction)
alertController.addAction(okAction)
self.present(alertController, animated: true, completion: nil)
See Alert With Destructive and OK Button:
In Swift 3, you can write this:
let alertController = UIAlertController(title: "Title", message: "This is my text", preferredStyle: UIAlertControllerStyle.alert)
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default)
{
(result : UIAlertAction) -> Void in
print("You pressed OK")
}
alertController.addAction(okAction)
self.present(alertController, animated: true, completion: nil)
For a basic alert message I like using an extension on UIViewController:
extension UIViewController {
func alertMessageOk(title: String, message: String) {
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.alert)
let action = UIAlertAction(title: "Ok", style: .default, handler: nil)
alert.addAction(action)
present(alert, animated: true, completion: nil)
}
}
Usage:
self.alertMessageOk(title: "Test Title", message: "Test message")
Swift 3
// Create message
let alertController = UIAlertController(title: "Title",
message: "Message",
preferredStyle: .actionSheet)
// Clear Action
let clearAction = UIAlertAction(title: "Clear",
style: .destructive,
handler: { (action:UIAlertAction!) in
print ("clear")
})
alertController.addAction(clearAction)
// Cancel
let cancelAction = UIAlertAction(title: "Cancel",
style: .cancel,
handler: { (action:UIAlertAction!) in
print ("Cancel")
})
alertController.addAction(cancelAction)
// Present Alert
self.present(alertController,
animated: true,
completion:nil)
UIAlertController *AC = UIAlertController.alertControllerWithTitle("Title",message:"Message",preferredStyle:UIAlertControllerStyleAlert)
UIAlertAction *ActionOne = [UIAlertAction actionWithTitle:"ActionOne" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) { NSLog("ActionOne")
} ]
UIAlertAction *ActionTwo = [UIAlertAction actionWithTitle:"ActionTwo" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) { NSLog("ActionTwo")
} ]
AC.addAction(ActionOne)
AC.addAction(ActionTwo)
self.presentViewController(AC,animated:true,completion:nil)
Try this code.
Ex
let actionSheetController: UIAlertController = UIAlertController(title: "Are you sure?", message: "", preferredStyle: .Alert)
let cancelAction: UIAlertAction = UIAlertAction(title: "NO", style: .Cancel) { action -> Void in
//Do your task
}
actionSheetController.addAction(cancelAction)
let nextAction: UIAlertAction = UIAlertAction(title: "YES", style: .Default) { action -> Void in
//Do your task //NSUserDefaults.standardUserDefaults().removePersistentDomainForName(NSBundle.mainBundle().bundleIdentifier!)
// NSUserDefaults.standardUserDefaults().synchronize()
}
actionSheetController.addAction(nextAction)
self.presentViewController(actionSheetController, animated: true, completion: nil)

How to add an action to a UIAlertView button using Swift iOS
var alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .Alert)
// Create the actions
var okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default) {
UIAlertAction in
NSLog("OK Pressed")
}
var cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {
UIAlertAction in
NSLog("Cancel Pressed")
}
// Add the actions
alertController.addAction(okAction)
alertController.addAction(cancelAction)
// Present the controller
self.presentViewController(alertController, animated: true, completion: nil)
This code will help
let alertController = UIAlertController(title: "Default AlertController", message: "A standard alert", preferredStyle: .Alert)
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel)
{
(action:UIAlertAction!) in
print("you have pressed the Cancel button");
}
alertController.addAction(cancelAction)
let OKAction = UIAlertAction(title: "OK", style: .Default)
{
(action:UIAlertAction!) in
print("you have pressed OK button");
}
alertController.addAction(OKAction)
self.presentViewController(alertController, animated: true, completion:nil)
I want to display a viewcontroller called InViewController, when the "OK" from the add.alertAction is pressed.
if ((user) != nil) {
let alert = UIAlertController(title: "Success", message: "Logged In", preferredStyle: .Alert)
alert.addAction(UIAlertAction(title: "OK", style: .Default) { _ in })
self.presentViewController(alert, animated: true){}
}
let alert = UIAlertController(title: "Success", message: "Logged In", preferredStyle: .Alert)
let action = UIAlertAction(title: "OK", style: .Default) { (action) -> Void in
let viewControllerYouWantToPresent = self.storyboard?.instantiateViewControllerWithIdentifier("SomeViewControllerIdentifier")
self.presentViewController(viewControllerYouWantToPresent!, animated: true, completion: nil)
}
alert.addAction(action)
self.presentViewController(alert, animated: true, completion: nil)
You can add a completionHandler to the UIAlertAction when you add it to do it what you want, like in the following way:
if ((user) != nil) {
let alert = UIAlertController(title: "Success", message: "Logged In", preferredStyle: .Alert)
let OKAction = UIAlertAction(title: "OK", style: .Default, handler: { _ -> Void in
let storyBoard = UIStoryboard(name: "Main", bundle: nil)
let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("ViewControllerA") as! ViewControllerA
self.presentViewController(nextViewController, animated: true, completion: nil)
})
alert.addAction(OKAction)
self.presentViewController(alert, animated: true){}
}
To set the StoryboardID you can use Interface Builder in the Identity Inspector, see the following picture:
I put everything in the above code referencing ViewControllerA, you have to set the name of your UIViewController according what you want.
EDIT:
You are pointing to a UIView or some other object on the StoryBoard. Press the yellow indicator on top of the other objects which is your UIViewController, like in the following picture:
I hope this help you.
Here's how you can do that ,
I'm just updating the good work of Victor Sigler
you follow his answer with this little update ..
private func alertUser( alertTitle title: String, alertMessage message: String )
{
let alert = UIAlertController(title: title, message: message, preferredStyle: .alert)
let actionTaken = UIAlertAction(title: "Success", style: .default) { (hand) in
let storyBoard = UIStoryboard(name: "Main", bundle: nil)
let destinationVC = storyBoard.instantiateViewController(withIdentifier: "IntroPage") as? StarterViewController
self.present(destinationVC!, animated: true, completion: nil)
}
alert.addAction(actionTaken)
self.present(alert, animated: true) {}
}
I have the following button action in a toolbar:
#IBAction func share(sender: AnyObject) {
let modifiedURL1 = "http://www.declassifiedandratified.com/search.html?q=\(self.searchBar.text)"
let modifiedURL = modifiedURL1.stringByReplacingOccurrencesOfString(" ", withString: "%20", options: NSStringCompareOptions.LiteralSearch, range: nil)
let alert = UIAlertController(title: "Share", message: "Share your findings", preferredStyle: UIAlertControllerStyle.ActionSheet)
let twBtn = UIAlertAction(title: "Twitter", style: UIAlertActionStyle.Default) { (alert) -> Void in
if SLComposeViewController.isAvailableForServiceType(SLServiceTypeTwitter){
var twitterSheet:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeTwitter)
twitterSheet.setInitialText("Look what I found on Declassified and Ratified: \(modifiedURL)")
self.presentViewController(twitterSheet, animated: true, completion: nil)
} else {
var alert = UIAlertController(title: "Accounts", message: "Please login to a Twitter account to share.", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
}
}
let fbBtn = UIAlertAction(title: "Facebook", style: UIAlertActionStyle.Default) { (alert) -> Void in
if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook){
var facebookSheet:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
facebookSheet.setInitialText("Look what I found on Declassified and Ratified: \(modifiedURL)")
self.presentViewController(facebookSheet, animated: true, completion: nil)
} else {
var alert = UIAlertController(title: "Accounts", message: "Please login to a Facebook account to share.", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction(UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil))
self.presentViewController(alert, animated: true, completion: nil)
}
}
let safariBtn = UIAlertAction(title: "Open in Safari", style: UIAlertActionStyle.Default) { (alert) -> Void in
let URL = NSURL(string: modifiedURL)
UIApplication.sharedApplication().openURL(URL!)
}
let cancelButton = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) { (alert) -> Void in
println("Cancel Pressed")
}
let textBtn = UIAlertAction(title: "Message", style: UIAlertActionStyle.Default) { (alert) -> Void in
if (MFMessageComposeViewController.canSendText()) {
let controller = MFMessageComposeViewController()
controller.body = "Look what I found on Declassified and Ratified: \(modifiedURL)"
controller.messageComposeDelegate = self
self.presentViewController(controller, animated: true, completion: nil)
}
}
alert.addAction(twBtn)
alert.addAction(fbBtn)
alert.addAction(safariBtn)
alert.addAction(textBtn)
alert.addAction(cancelButton)
self.presentViewController(alert, animated: true, completion: nil)
}
However, this code crashes when called on an iPad with a sigbart crash (that is all I can see in the console). I see this is a common problem but the other solutions have not worked for me. I even set the version to the latest iOS and that didn't fix it. Can someone explain?
On an iPad, an action sheet is a popover. Therefore you must give its UIPopoverPresentationController a sourceView and sourceRect, or barButtonItem, so that it has something to attach its arrow to.
I want to add another button other than the "OK" button which should just dismiss the alert.
I want the other button to call a certain function.
var logInErrorAlert: UIAlertView = UIAlertView()
logInErrorAlert.title = "Ooops"
logInErrorAlert.message = "Unable to log in."
logInErrorAlert.addButtonWithTitle("Ok")
How do I add another button to this alert, and then allow it to call a function once clicks so lets say we want the new button to call:
retry()
The Swifty way is to use the new UIAlertController and closures:
// Create the alert controller
let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .Alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default) {
UIAlertAction in
NSLog("OK Pressed")
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {
UIAlertAction in
NSLog("Cancel Pressed")
}
// Add the actions
alertController.addAction(okAction)
alertController.addAction(cancelAction)
// Present the controller
self.presentViewController(alertController, animated: true, completion: nil)
Swift 3:
// Create the alert controller
let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel) {
UIAlertAction in
NSLog("Cancel Pressed")
}
// Add the actions
alertController.addAction(okAction)
alertController.addAction(cancelAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
func showAlertAction(title: String, message: String){
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertController.Style.alert)
alert.addAction(UIAlertAction(title: "Ok", style: UIAlertAction.Style.default, handler: {(action:UIAlertAction!) in
print("Action")
}))
alert.addAction(UIAlertAction(title: "Cancel", style: UIAlertAction.Style.default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
UIAlertViews use a delegate to communicate with you, the client.
You add a second button, and you create an object to receive the delegate messages from the view:
class LogInErrorDelegate : UIAlertViewDelegate {
init {}
// not sure of the prototype of this, you should look it up
func alertView(view :UIAlertView, clickedButtonAtIndex :Integer) -> Void {
switch clickedButtonAtIndex {
case 0:
userClickedOK() // er something
case 1:
userClickedRetry()
/* Don't use "retry" as a function name, it's a reserved word */
default:
userClickedRetry()
}
}
/* implement rest of the delegate */
}
logInErrorAlert.addButtonWithTitle("Retry")
var myErrorDelegate = LogInErrorDelegate()
logInErrorAlert.delegate = myErrorDelegate
Swift 5+
let alert = UIAlertController(title: "Cart!", message: "Are you sure want to remove order details?", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "YES", style:
UIAlertAction.Style.default) {
UIAlertAction in
print("Yes Pressed")
}
let cancelAction = UIAlertAction(title: "CANCEL", style:
UIAlertAction.Style.cancel) {
UIAlertAction in
print("Cancel Pressed")
}
// Add the actions
alert.addAction(okAction)
alert.addAction(cancelAction)
self.present(alert, animated: true, completion: nil)
OR
let alert = UIAlertController(title: "Alert!", message: "Are you sure want to remove your request?", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "YES", style: .destructive) {
_ in
print("Yes Pressed")
self.funRemoveRequest(requestID: (self.requestStatusModel?.data?[sender.tag].id)!)
}
let cancelAction = UIAlertAction(title: "CANCEL", style: .cancel) {
_ in
print("Cancel Pressed")
}
// Add the actions
alert.addAction(okAction)
alert.addAction(cancelAction)
self.present(alert, animated: true, completion: nil)
Swift 4 Update
// Create the alert controller
let alertController = UIAlertController(title: "Title", message: "Message", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel) {
UIAlertAction in
NSLog("Cancel Pressed")
}
// Add the actions
alertController.addAction(okAction)
alertController.addAction(cancelAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
based on swift:
let alertCtr = UIAlertController(title:"Title", message:"Message", preferredStyle: .Alert)
let Cancel = AlertAction(title:"remove", style: .Default, handler: {(UIAlertAction) -> Void in })
let Remove = UIAlertAction(title:"remove", style: .Destructive, handler:{(UIAlertAction)-> Void
inself.colorLabel.hidden = true
})
alertCtr.addAction(Cancel)
alertCtr.addAction(Remove)
self.presentViewController(alertCtr, animated:true, completion:nil)}
Swift 3.0 Version of Jake's Answer
// Create the alert controller
let alertController = UIAlertController(title: "Alert!", message: "There is no items for the current user", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
}
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel) {
UIAlertAction in
NSLog("Cancel Pressed")
}
// Add the actions
alertController.addAction(okAction)
alertController.addAction(cancelAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
See my code:
#IBAction func foundclicked(sender: AnyObject) {
if (amountTF.text.isEmpty)
{
let alert = UIAlertView(title: "Oops! Empty Field", message: "Please enter the amount", delegate: nil, cancelButtonTitle: "OK")
alert.show()
}
else {
var alertController = UIAlertController(title: "Confirm Bid Amount", message: "Final Bid Amount : "+amountTF.text , preferredStyle: .Alert)
var okAction = UIAlertAction(title: "Confirm", style: UIAlertActionStyle.Default) {
UIAlertAction in
JHProgressHUD.sharedHUD.loaderColor = UIColor.redColor()
JHProgressHUD.sharedHUD.showInView(self.view, withHeader: "Amount registering" , andFooter: "Loading")
}
var cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel) {
UIAlertAction in
alertController .removeFromParentViewController()
}
alertController.addAction(okAction)
alertController.addAction(cancelAction)
self.presentViewController(alertController, animated: true, completion: nil)
}
}
this is for swift 4.2, 5 and 5+
let alert = UIAlertController(title: "ooops!", message: "Unable to login", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Ok", style: .default, handler: nil))
self.present(alert, animated: true)
