I want after signup the alert controller should pop up and then go the loginFirstViewController but this is not going to happen why?? it only goes to loginfirstviewcontroller instead of poping up alert controller
if error == nil {
FIRAuth.auth()?.currentUser!.sendEmailVerification(completion: { (error) in
})
print("You have successfully signed up")
//Goes to the Setup page which lets the user take a photo for their profile picture and also chose a username
let alertController = UIAlertController(title: "Successful!", message: "Email Verification link sent", preferredStyle: .alert)
let alertActionOkay = UIAlertAction(title: "Okay", style: .default)
let vc = self.storyboard?.instantiateViewController(withIdentifier: "LoginFirstViewController")
self.present(vc!, animated: true, completion: nil)
alertController.addAction(alertActionOkay)
self.present(alertController, animated: true, completion: nil)
}
You directly opened new viewcontroller to prevent this you should add completion handler for uialertaction. When the user press ok button you can open other viewcontroller
let alertController = UIAlertController(title: "Successful!", message: "Email Verification link sent", preferredStyle: .alert)
let alertActionOkay = UIAlertAction(title: "Okay", style: .default) { (action) in
let vc = self.storyboard?.instantiateViewController(withIdentifier: "LoginFirstViewController")
self.present(vc!, animated: true, completion: nil)
}
alertController.addAction(alertActionOkay)
self.present(alertController, animated: true, completion: nil)

Navigation bar does not appear after login button pressed when it moves to Home view controller and I have setup my storyboard and put all thing well but I think i am stuck at this point in code.
Actually there is no segue but coding instead so How I do navigation working?
Code I used to perform Navigation
let vc = self.storyboard?.instantiateViewController(withIdentifier: "Home")
self.present(vc!, animated: true, completion: nil)
#IBAction func loginAction(_ sender: Any) {
if self.emailTextField.text == "" || self.passwordTextField.text == "" {
//Alert to tell the user that there was an error because they didn't fill anything in the textfields because they didn't fill anything in
let alertController = UIAlertController(title: "Error", message: "Please enter an email and password.", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
} else {
FIRAuth.auth()?.signIn(withEmail: self.emailTextField.text!, password: self.passwordTextField.text!) { (user, error) in
if error == nil {
//Print into the console if successfully logged in
print("You have successfully logged in")
//Go to the HomeViewController if the login is sucessful
let vc = self.storyboard?.instantiateViewController(withIdentifier: "Home")
self.present(vc!, animated: true, completion: nil)
} else {
//Tells the user that there is an error and then gets firebase to tell them the error
let alertController = UIAlertController(title: "Error", message: error?.localizedDescription, preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "OK", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}
}
Replace your code:
let vc = self.storyboard?.instantiateViewController(withIdentifier: "Home")
self.present(vc!, animated: true, completion: nil)
With this Code:
let vc : YourViewController = self.storyboard?.instantiateViewController(withIdentifier: "Home")as! YorViewController
let navController = UINavigationController(rootViewController: vc)
self.present(navController, animated: true, completion: nil)
You are just trying to present the view controller with out Navigation. Give it Navigation programmatically then it will show Navigation bar.
Are you really using navigationController? If so, should it be pushViewController rather than present?
navigationController?.pushViewController(vc, animated: true)
How to show or link to new ViewController when push button on alert?
This is my code
let alert = UIAlertController(title: validateQRObj.responseDescription, message: validateQRObj.productName, preferredStyle: .alert)
let action = UIAlertAction(title: "OK", style: .default) { (action) -> Void in
let viewController = self.storyboard?.instantiateViewController(withIdentifier: "ProductDetialViewController")
self.present(viewController!, animated: true, completion: nil)
}
alert.addAction(action)
self.present(alert, animated: true, completion: nil)
Control drag from View Controller 1 (The yellow dot) to any where on View Controller 2 and then click on the Segue. Show the Attributes inspector and Under Storyboard Segue identifier name the identifier VC2
If this is the answer you were looking for don't forget to except the answer.
func alert(){
let alertController = UIAlertController(title: "Open View Controller. ", message: "Press Ok to open View Controller number 2.", preferredStyle: UIAlertControllerStyle.alert)
let ok = UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler: {(action) -> Void in
//The (withIdentifier: "VC2") is the Storyboard Segue identifier.
self.performSegue(withIdentifier: "VC2", sender: self)
})
alertController.addAction(ok)
self.present(alertController, animated: true, completion: nil)
}
For me it doesn't work. I made :
func alert(){
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let twop = storyboard.instantiateViewController(withIdentifier: "Accueil") as! Accueil
let alertController = UIAlertController(title: "Open new View !", message: "Clic to ok", preferredStyle: UIAlertControllerStyle.alert)
let ok = UIAlertAction(title: "Ok", style: UIAlertActionStyle.default, handler: {(action) -> Void in
self.navigationController?.show(twop, sender: self)
})
alertController.addAction(ok)
self.present(alertController, animated: true, completion: nil)
}
and now it's working !!
I have got the below piece of code :
let title = "You are not connected to DropBox"
let message = "Please go back to the main page and try to log in again"
let okText = "OK"
let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert)
let okayButton = UIAlertAction(title: okText, style: UIAlertActionStyle.Cancel, handler: nil)
alert.addAction(okayButton)
if dbRestClient == nil{
print("please refresh me")
presentViewController(alert, animated: true, completion: nil)
}`
However my alert doesn't show up. I am calling this alert from a View Controller that actually shows on the page so its not the case where my VC is working behind the scene. Please let me know what I am doing wrong here.
Use self.presentViewController(alert, animated: true, completion: nil) instead.
Should work after adding self.
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) {}
}
The UIAlertViewController shows all my text but on clicking doesn't switch to the other View. Here's the code:
let alertController = UIAlertController(title: "Risposta Esatta", message:"", preferredStyle: UIAlertControllerStyle.Alert)
alertController.addAction(UIAlertAction(title: "Avanti", style:UIAlertActionStyle.Default,handler: {(UIAlertAction) in
let secondViewController:SecondViewController = SecondViewController()
self.presentViewController(secondViewController, animated: true, completion: nil)
}))
This just worked for me:
#IBAction func choiceBtn(sender: UIButton) {
let alertController = UIAlertController(title: "Hello!", message: "This is Alert sample.", preferredStyle: .Alert)
let otherAction = UIAlertAction(title: "OK", style: .Default) {
action in println("pushed OK!")
}
let cancelAction = UIAlertAction(title: "CANCEL", style: .Cancel) {
action in self.performSegueWithIdentifier("VC2", sender: self)
}
alertController.addAction(otherAction)
alertController.addAction(cancelAction)
presentViewController(alertController, animated: true, completion: nil)
}
I created a modal presented segue from VC1 to VC2 and also named the identifier VC2. This code I adapted from the GitHub UIAlertController example here:
https://github.com/eversense/Swift-UIAlertController-Example
There was no segue to another ViewController, so I added that to show you.
