HMSegmentedControlにてタブ部分とScrollViewを連動させる方法

Question

###前提・実現したいこと
http://dev.classmethod.jp/smartphone/ios_oss_hmsegmentedcontrol/
上記サイトを参考にHMSegmentedControlにてタブを作成中です。

そこで、タブ部分を横スライドやタップするとそれに伴いscrollviewも切り替わるんですが、
scrollview部分を横スライドしてもscrollviewの切り替えに伴ってタブが切り替わりません。

これを連動させるにはどうすればいいでしょうか。よろしくお願いします。

    override func viewDidLoad() {
        super.viewDidLoad()

        segmentedControl = HMSegmentedControl(frame: CGRectMake(0, statusbarHeight, self.view.frame.size.width, self.headerView.frame.size.height))
        segmentedControl.selectionIndicatorColor = UIColor(red: 1.18, green: 1.80, blue: 1.53, alpha: 0.8)
        
        let segmentControls = HMSegmentedControl(frame: CGRectMake(0, statusbarHeight, self.view.frame.size.width, self.headerView.frame.size.height))
        self.view.addSubview(segmentControls)
        
        segmentControls.sectionImages = [UIImage(named: "star")!, UIImage(named: "home")!, UIImage(named: "search")!]
        segmentControls.sectionSelectedImages = [UIImage(named: "starSelected")!, UIImage(named: "homeSelected")!, UIImage(named: "searchSelected")!]
        segmentControls.selectedSegmentIndex = 1

        let blockVariable :IndexChangeBlock = {(index:Int) -> Void in
            let frame = CGRectMake(self.scrollView.frame.size.width * CGFloat(index), 0, self.scrollView.frame.size.width, self.scrollView.frame.size.height)
            self.scrollView.scrollRectToVisible(frame, animated: true)
            print(index)
        }
        segmentControls.indexChangeBlock = blockVariable
        
        scrollView.pagingEnabled = true
        scrollView.showsHorizontalScrollIndicator = false
        scrollView.contentSize = CGSizeMake(self.view.frame.size.width * 3, self.scrollView.frame.size.height)
        scrollView.delegate = self.uiScrollViewDelegate
        
        let page1view = UIView(frame: CGRectMake(0, 0, self.view.frame.size.width, self.scrollView.frame.size.height))
        page1view.backgroundColor = UIColor.blueColor()
        self.scrollView.addSubview(page1view)

        let page2view = UIView(frame: CGRectMake(self.view.frame.size.width, 0, self.view.frame.size.width, self.scrollView.frame.size.height))
        page2view.backgroundColor = UIColor.redColor()
        self.scrollView.addSubview(page2view)

        let page3view = UIView(frame: CGRectMake(self.view.frame.size.width * 2, 0, self.view.frame.size.width, self.scrollView.frame.size.height))
        page3view.backgroundColor = UIColor.greenColor()
        self.scrollView.addSubview(page3view)
        
        
        // Do any additional setup after loading the view, typically from a nib.
        
    }
