转到下一页按钮单击PageViewController

Question

我已经创建了PageViewController，我正在尝试进行测验，当您按下按钮时，它将滑动到下一个视图。我似乎无法让这个工作。到目前为止，我添加了一个包含按钮的tableView，我想用这个手势。除此之外我想禁用滚动手势，因此用户无法手动滚动。这是可能的还是使用scrollView更有意义呢？

viewDidLoad中

    self.pageViewController = self.storyboard?.instantiateViewControllerWithIdentifier("QuizPageViewController") as! UIPageViewController
    self.pageViewController.dataSource = self

    let startVC = self.viewControllerAtIndex(0) as QuestionViewController
    let viewControllers = NSArray(object: startVC)

    self.pageViewController.setViewControllers(viewControllers as? [UIViewController], direction: .Forward, animated: true, completion: nil)
    self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.width, self.view.frame.size.height)

    self.addChildViewController(self.pageViewController)
    self.view.addSubview(self.pageViewController.view)
    self.pageViewController.didMoveToParentViewController(self)

PageViewController委托

func viewControllerAtIndex(index: Int) -> QuestionViewController
{
    if ((self.pageTitles.count == 0) || (index >= self.pageTitles.count)) {
        return QuestionViewController()
    }

    let vc: QuestionViewController = self.storyboard?.instantiateViewControllerWithIdentifier("QuestionViewController") as! QuestionViewController
    vc.questionText = self.pageTitles[index] as! String
    vc.pageIndex = index
    vc.pageCount = self.pageTitles.count
    return vc
}

func pageViewController(pageViewController: UIPageViewController, viewControllerBeforeViewController viewController: UIViewController) -> UIViewController?
{
    let vc = viewController as! QuestionViewController
    var index = vc.pageIndex as Int
    if (index == 0 || index == NSNotFound)
    {
        return nil   
    }
    index--
    return self.viewControllerAtIndex(index)   
}

func pageViewController(pageViewController: UIPageViewController, viewControllerAfterViewController viewController: UIViewController) -> UIViewController? {

    let vc = viewController as! QuestionViewController
    var index = vc.pageIndex as Int
    print(index)
    if (index == NSNotFound)
    {
        return nil
    }
    index++
    if (index == self.pageTitles.count)
    {
        return nil
    }
    return self.viewControllerAtIndex(index)
}

func presentationIndexForPageViewController(pageViewController: UIPageViewController) -> Int
{
    return 0
}
