iOS 8 - Display an alert

The UIAlertView class is deprecated in iOS8. In place of it is the more adaptive UIAlertController class. Here is a quick example of how to display an alert in iOS 8:

    func displayAlert(title:String, content:String) {

        var alertController = UIAlertController(

            title: title,

            message: content,

            preferredStyle: UIAlertControllerStyle.Alert)

        

        var okAction = UIAlertAction(

            title: "OK", style: UIAlertActionStyle.Default) {

                (action) -> Void in

                println("Tapped on OK")

        }

        

        alertController.addAction(okAction)

        self.presentViewController(alertController, animated: true, completion: nil)

    }

To display an alert, you can call the displayAlert() function like this:

self.displayAlert("Hello", content: "Hello, iOS 8")

The above will display an alert like the following:
