问题描述

我想获取 pageViewController 的当前索引,我不知道如何获取可见页面索引.

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

您可以使用 didFinishAnimating,并为 viewcontrollers 设置标签.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
}
