ios – Swift中的PageViewController当前页面索引

我想获取一个pageViewController的当前索引,我不知道我如何获取可见页索引.

func pageViewController(pageViewController: UIPageViewController,didFinishAnimating finished: Bool,prevIoUsViewControllers: [UIViewController],transitionCompleted completed: Bool)
{
    // How to get it?

}

解决方法

您可以使用didFinishAnimating,并将标签设置为查看控制器.尝试这个

func pageViewController(pageViewController: UIPageViewController,transitionCompleted completed: Bool)
{
   if (!completed)
  {
    return
  }
  self.pageControl.currentPageIndex = pageViewController.viewControllers!.first!.view.tag //Page Index
}
