借助计时器，Swift 4自动在页面视图控制器中滑动

Question

我正在尝试使用100010000001000000000101000000011 在auto sliding中创建page view controller。在这里，我尝试使用下面的代码，但得到结果，它正在重复图像的第一个swift 4。我需要知道，如何实现下一个索引的移动？

index

Answer 1

    // Image array
    var name = ["one.png","two.png","three.png","four.png"]
    var currentIndex = -1

    // Timer in viewdidload()
    tTime = Timer.scheduledTimer(timeInterval: 4, target: self, selector: #selector(changeSlide), userInfo: nil, repeats: true)


    // Timer function call
    @objc func changeSlide() 
   {
    currentIndex = (currentIndex == name.count - 1) ? 0 : currentIndex + 1

    let pageContentViewController = self.viewControllerAtIndex(index: currentIndex)
    self.pageViewController.setViewControllers([pageContentViewController!], direction: UIPageViewControllerNavigationDirection.forward, animated: true, completion: nil)
}
