问题描述

我想获取pageViewController的当前索引，我不知道如何获得可见页面索引。

I want to get current index of a pageViewController, I don't know how I get the visible pages index.

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

}

推荐答案

你可以使用didFinishAnimating，并将标签设置为viewcontrollers。试试这个

You can use didFinishAnimating, and set tags to viewcontrollers. try this

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