This is good appraoch ...

func popUpController()
{

    let alertController = UIAlertController(title: "\n\n\n\n\n\n", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)

    let margin:CGFloat = 8.0
    let rect = CGRectMake(margin, margin, alertController.view.bounds.size.width - margin * 4.0, 100.0)
    let customView = UITextView(frame: rect)

    customView.backgroundColor = UIColor.clearColor()
    customView.font = UIFont(name: "Helvetica", size: 15)



  //  customView.backgroundColor = UIColor.greenColor()
    alertController.view.addSubview(customView)

    let somethingAction = UIAlertAction(title: "Something", style: UIAlertActionStyle.Default, handler: {(alert: UIAlertAction!) in print("something")

        print(customView.text)

    })

    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: {(alert: UIAlertAction!) in print("cancel")})

    alertController.addAction(somethingAction)
    alertController.addAction(cancelAction)

    self.presentViewController(alertController, animated: true, completion:{})
