Turns a UISegmentedControl into a vertical layout.

UISegmentedControl+VerticalLayout.swift

import UIKit

extension UISegmentedControl {
    func goVertical() {
        self.transform = CGAffineTransformMakeRotation(CGFloat(M_PI_2))
        for segment in self.subviews {
            for segmentSubview in segment.subviews {
                if segmentSubview is UILabel {
                    (segmentSubview as UILabel).transform = CGAffineTransformMakeRotation(CGFloat(-M_PI_2))
                }
            }
        }
    }
    func restoreHorizontal() {
        self.transform = CGAffineTransformIdentity
        for segment in self.subviews {
