I am creating an app where when the user enters the page, an alert view pops up saying "Click on the button to proceed". How can I make the alert view show once in the view controller? Thanks for any help.

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    let alertController = UIAlertController(title: "Info", message: "Click on the button to proceed", preferredStyle: UIAlertControllerStyle.alert)
    let myBackSign = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil)
    alertController.addAction(myBackSign )
    self.present(alertController, animated: true, completion: nil)
}

What do you by once? Is it in the entire app lifecycle? – Aditya Srivastava Aug 18 '17 at 06:16
@Lamar if I move the code to `viewWillAppear` will that show only once on the view controller? – Aug 18 '17 at 06:18
@rmaddy - but questioner need only one time – Anbu.Karthik Aug 18 '17 at 06:18

@Anbu.Karthik But that doesn't change the fact that `viewDidLoad` is the wrong place to present another view controller. – rmaddy Aug 18 '17 at 06:19
@rmaddy - else alternate we need to create one bool value and need to check based on condition – Anbu.Karthik Aug 18 '17 at 06:20
@rmaddy do you know how to show the alert view once in the view controller? – Aug 18 '17 at 06:21
