swift - 如何在 UIPageViewController SWIFT 的最后一个 View 上隐藏点

Question

我希望能够隐藏 UIPageViewController 的最后一个 View 上的分页点。有这个question已经问过了，但从未得到回答。

如果有人可以给我概述一下这是如何实现的。

谢谢

编辑:

func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {
        pageControl.hidden = true
        print(pageControl.hidden)//Always is false
    }

使用 UIPageViewControllerDelegate 方法:

let pageControl = UIPageControl()

override func viewDidLoad(){
    super.viewDidLoad()
    pageControl.numberOfPages = numberOfPages()
    pageControl.currentPage = 0
    view.addSubview(pageControl)
    pageControl.currentPageIndicatorTintColor = UIColor.whiteColor()
    pageControl.pageIndicatorTintColor = UIColor.whiteColor().colorWithAlphaComponent(0.4)
}

func numberOfPages() -> Int {
    return 4 //your number of pages
}

func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool) {
    if (index == numberOfPages()-1){
          pageControl.hidden = true
    }else{
          pageControl.hidden = false
    }
}

您也可以迁移到 icarousel，它非常强大且易于实现 https://www.youtube.com/watch?v=OLvZbXOAZQY
