UIAlertController addActionが動作しない

Question

UIAlertControllerが警告を画面に正しく表示していますが、xCodeシミュレータでokを押すとアラートを残さないようにします。 UIAlertActionStyle.Cancel

func displayAlertMessage(userMessage:String) { 

let myAlert = UIAlertController(title: "Alert", message: userMessage, preferredStyle: UIAlertControllerStyle.Alert); 

let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Cancel, handler: nil); 

myAlert.addAction(okAction); 

self.presentViewController(myAlert, animated: true, completion: nil); 

} 

からalert view image

func displayAlertMessage(userMessage:String) { 

    let myAlert = UIAlertController(title: "Alert", message: userMessage, preferredStyle: UIAlertControllerStyle.Alert); 

    let okAction = UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler: nil); 

    myAlert.addAction(okAction); 

    self.presentViewController(myAlert, animated: true, completion: nil); 

}

変更UIAlertActionStyle.Default、あなたは

OK

let okAction = UIAlertAction(title: "OK", style: .Default) { (action) in 
     //do whatever you want to do here 
    // for e.g dismiss view controller or segue your view controller etc. 
    }
