UIPageViewControler是否从didFinishAnimating方法获取当前数字页?

这是我的作品,感谢克鲁梅尔!

- (void)pageViewController:(UIPageViewController *)pageViewController didFinishAnimating:(BOOL)finished previousViewControllers:(NSArray *)previousViewControllers transitionCompleted:(BOOL)completed 
{
   if (completed) {
    int currentIndex = ((UIViewController *)[self.pageViewController.viewControllers objectAtIndex:0]).view.tag;
    self.pageControl.currentPage = currentIndex;
     }
  }
