Swift alert view with OK and Cancel: which button tapped?

Question

I have an alert view in Xcode written in Swift and I\'d like to determine which button the user selected (it is a confirmation dialog) to do nothing or to execute something.

Answer 1

var refreshAlert = UIAlertController(title: "Log Out", message: "Are You Sure to Log Out ? ", preferredStyle: UIAlertControllerStyle.Alert)

refreshAlert.addAction(UIAlertAction(title: "Confirm", style: .Default, handler: { (action: UIAlertAction!) in
    self.navigationController?.popToRootViewControllerAnimated(true)
}))

refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .Default, handler: { (action: UIAlertAction!) in

    refreshAlert .dismissViewControllerAnimated(true, completion: nil)


}))

presentViewController(refreshAlert, animated: true, completion: nil)
