In this short Swift code example we will create an Alert dialog message with only one “OK” button.
- Create UIAlertController with Title and Message to display
- Add UIAlertAction or OK button to UIAlertController
- Handle UIAlertAction to know when user taps on OK button
let alertController = UIAlertController(title: "Alert title", message: "Message to display", preferredStyle: .alert) let OKAction = UIAlertAction(title: "OK", style: .default) { (action:UIAlertAction!) in // Code in this block will trigger when OK button tapped. print("Ok button tapped"); } alertController.addAction(OKAction) self.present(alertController, animated: true, completion:nil)
