    func setBackgroundColor (value : Int) {        if (value == 0) {            // Red            self.view.backgroundColor = UIColor.redColor()        }        else if (value == 1) {            //Green            self.view.backgroundColor = UIColor.greenColor()        }        else {            // BLue            self.view.backgroundColor = UIColor.blueColor()        }        segmentedController.tintColor = self.view.backgroundColor        segmentedController.backgroundColor = UIColor.whiteColor()        segmentedController.layer.borderColor = UIColor.whiteColor().CGColor        segmentedController.layer.borderWidth = 2        segmentedController.layer.cornerRadius = segmentedController.frame.size.height/2        segmentedController.clipsToBounds = true                            }    }
