我有一个非常标准的 UIPageViewController，它加载了 3 个单独的 UIViewController 来滑动浏览。
其中一个 UIViewController 需要一个 UIScrollView，它仍然可以在不触发 UIPageViewController 的手势识别器的情况下运行。
如果触摸是从那里开始的，我如何才能将手势限制在 UIScrollView 上，这样它就不会触发转换？
这是设置图:
UIPageViewController 来源:
class MyPageViewController: UIPageViewController
{
fileprivate lazy var pages: [UIViewController] = {
return [
self.getViewController(withIdentifier: "MyPage1"),
self.getViewController(withIdentifier: "MyPage2"),
self.getViewController(withIdentifier: "MyPage3"),
]
}()
fileprivate func getViewController(withIdentifier identifier: String) -> UIViewController
{
return UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: identifier)
}
var imageView: UIImageView?
var backgroundVideo : VideoBackground!
override func viewDidLoad()
{
super.viewDidLoad()
self.dataSource = self
self.delegate = self as? UIPageViewControllerDelegate
if let firstVC = pages.first
{
setViewControllers([firstVC], direction: .forward, animated: true, completion: nil)
}
}
}
extension MyPageViewController: UIPageViewControllerDataSource
{
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
guard let viewControllerIndex = pages.index(of: viewController) else { return nil }
let previousIndex = viewControllerIndex - 1
guard previousIndex >= 0 else { return nil }
guard pages.count > previousIndex else { return nil }
return pages[previousIndex]
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController?
{
guard let viewControllerIndex = pages.index(of: viewController) else { return nil }
let nextIndex = viewControllerIndex + 1
guard nextIndex < pages.count else { return nil }
guard pages.count > nextIndex else { return nil }
return pages[nextIndex]
}
private func setupPageControl() {
let appearance = UIPageControl.appearance()
appearance.pageIndicatorTintColor = UIColor.black
appearance.currentPageIndicatorTintColor = UIColor.white
appearance.backgroundColor = UIColor.clear
appearance.isOpaque = false
}
func presentationCount(for pageViewController: UIPageViewController) -> Int {
setupPageControl()
return self.pages.count
}
func presentationIndex(for pageViewController: UIPageViewController) -> Int {
return 0
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
for view in self.view.subviews {
if view is UIScrollView {
view.frame = UIScreen.main.bounds
} else if view is UIPageControl {
view.backgroundColor = UIColor.clear
}
}
}
}
extension MyPageViewController: UIPageViewControllerDelegate {}
最佳答案
这是一个 Storyboard示例，无需对您发布的代码进行任何编辑即可运行(将 Main.storyboard 的源代码替换为以下内容)。
第一个 VC 有一个 ScrollView ，其中包含一个带有 6 个标签的堆栈 View 。堆栈 View 具有垂直 Spacing = 160，因此您应该获得大量垂直滚动，并且其宽度设置为 ScrollView 的宽度 + 120，因此您也将获得水平滚动。
