我想获取 pageViewController 的当前索引，我不知道如何获取可见页面索引。
func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool,previousViewControllers: [UIViewController],transitionCompleted completed: Bool)
{
// How to get it?
}
最佳答案
您可以使用 didFinishAnimating，并将标签设置到 View Controller 。试试这个
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
}
关于ios - UIPageViewController Swift 中的当前页面索引，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32822794/
