I created a alerMessage class .I can call any where in my application

//Common Alert Message Class 

class AlertMessage {

internal static var alertMessageController:UIAlertController!

internal static func disPlayAlertMessage(titleMessage:String, alertMsg:String){


    AlertMessage.alertMessageController = UIAlertController(title: titleMessage, message:
        alertMsg, preferredStyle: UIAlertControllerStyle.Alert)

    AlertMessage.alertMessageController.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default,handler: nil))
    if let controller = UIApplication.sharedApplication().keyWindow?.rootViewController?.presentedViewController {
        controller.presentViewController(AlertMessage.alertMessageController, animated: true, completion: nil)
    }
    else{
        UIApplication.sharedApplication().delegate?.window!!.rootViewController?.presentViewController(AlertMessage.alertMessageController, animated: true, completion: nil)
    }

    return

 }
