我有一个视图容器包含UIPageViewController。对他来说，它们与UIImageView的2 viewController相关联。它几乎适用于所有方面我无法更改动画来滚动图像。动画总是那个页面卷曲，而我想要一个简单的卷轴。怎么做？转换页面与uipageviewcontroller
class MyPageViewController: UIPageViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate {
var pages = [UIViewController]()
override func viewDidLoad() {
super.viewDidLoad()
self.delegate = self
self.dataSource = self
let page1: UIViewController! = storyboard?.instantiateViewController(withIdentifier: "page1")
let page2: UIViewController! = storyboard?.instantiateViewController(withIdentifier: "page2")
pages.append(page1)
pages.append(page2)
setViewControllers([page1], direction: UIPageViewControllerNavigationDirection.forward, animated: false, completion: nil)
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
let currentIndex = pages.index(of: viewController)!
let previousIndex = abs((currentIndex - 1) % pages.count)
return pages[previousIndex]
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
let currentIndex = pages.index(of: viewController)!
let nextIndex = abs((currentIndex + 1) % pages.count)
return pages[nextIndex]
}
private func presentationCountForPageViewController(pageViewController: UIPageViewController) -> Int {
return pages.count
}
private func presentationIndexForPageViewController(pageViewController: UIPageViewController) -> Int {
return 0
}
}
