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
}
