Writing handler for UIAlertAction

Question

I\'m presenting a UIAlertView to the user and I can\'t figure out how to write the handler. This is my attempt:

let alert = UIAlertController(ti         


        

Answer 1

In Swift 4 :

let alert=UIAlertController(title:"someAlert", message: "someMessage", preferredStyle:UIAlertControllerStyle.alert )

alert.addAction(UIAlertAction(title: "ok", style: UIAlertActionStyle.default, handler: {
        _ in print("FOO ")
}))

present(alert, animated: true, completion: nil)
