【中文标题】禁用 UIPageViewController 反弹【英文标题】：Disable UIPageViewController bounce 【发布时间】：2014-02-15 13:30:36 【问题描述】：为此搜索了很多，但还没有找到合适的解决方案。
是否可以禁用UIPageViewController 的反弹效果并仍然使用UIPageViewControllerTransitionStyleScroll？
【问题讨论】：
如果你想移除弹跳，你可以使用 UIPageViewControllerTransitionStylePageCurl 样式。 @pawan 我想使用 UIPageViewControllerTransitionStyleScroll 【参考方案1】：禁用 UIPageViewController 的反弹
将 <UIScrollViewDelegate> 委托添加到 UIPageViewController 的标题
将 UIPageViewController 的底层 UIScrollView 的委托设置为 viewDidLoad 中的父代：
for (UIView *view in self.view.subviews)
if ([view isKindOfClass:[UIScrollView class]])
((UIScrollView *)view).delegate = self;
break;
scrollViewDidScroll 的实现是在用户超出范围，如下所示：
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
if (_currentPage == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width)
scrollView.contentOffset = CGPointMake(scrollView.bounds.size.width, 0);
else if (_currentPage == totalViewControllersInPageController-1 && scrollView.contentOffset.x > scrollView.bounds.size.width)
scrollView.contentOffset = CGPointMake(scrollView.bounds.size.width, 0);
最后，scrollViewWillEndDragging的实现是为了处理用户在第一页从左向右快速滑动，第一页不会向左弹跳的bug场景（由于上面的函数），但会因（可能）滑动速度而在右侧反弹。最后，当反弹回来时，UIPageViewController 会触发翻页到第二页（这当然不是预期的）。
- (void)scrollViewWillEndDragging:(UIScrollView *)scrollView withVelocity:(CGPoint)velocity targetContentOffset:(inout CGPoint *)targetContentOffset
if (_currentPage == 0 && scrollView.contentOffset.x <= scrollView.bounds.size.width)
*targetContentOffset = CGPointMake(scrollView.bounds.size.width, 0);
else if (_currentPage == totalViewControllersInPageController-1 && scrollView.contentOffset.x >= scrollView.bounds.size.width)
*targetContentOffset = CGPointMake(scrollView.bounds.size.width, 0);

要放入viewDidLoad的代码：
for subview in self.view.subviews
if let scrollView = subview as? UIScrollView
scrollView.delegate = self
break;
scrollViewDidScroll的实现：
func scrollViewDidScroll(_ scrollView: UIScrollView)
if (currentPage == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width)
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0);
else if (currentPage == totalViewControllersInPageController - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width)
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0);
scrollViewWillEndDragging的实现：
func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)
if (currentPage == 0 && scrollView.contentOffset.x <= scrollView.bounds.size.width)
targetContentOffset.pointee = CGPoint(x: scrollView.bounds.size.width, y: 0);
else if (currentPage == totalViewControllersInPageController - 1 && scrollView.contentOffset.x >= scrollView.bounds.size.width)
targetContentOffset.pointee = CGPoint(x: scrollView.bounds.size.width, y: 0);
【讨论】：
我不明白这一行 *targetContentOffset = CGPointMake(scrollView.bounds.size.width, 0);你能解释一下吗？ @Andrespch UIPageViewController 的底层滚动视图会将 visible ViewController 的视图放置在偏移量：(scrollView.bounds.size.width, 0)。即前一个ViewController的view放在位置(0,0)~(scrollView.bounds.size.width,0)，下一个ViewController的view放在位置(scrollView.bounds.size.width*2, 0)~( scrollView.bounds.size.width*3,0) 当用户滚动 UIPageViewController 以显示上一个和下一个视图时 @DongMaisPageToBounce 和 _currentPage 应该是什么类型？我无法理解代码。你能逐步解释一下吗？我认为这是互联网上解决此问题的唯一方法（一直在寻找几个小时）。
谢谢 ;) 我试图解决这个问题太久了 :)

Addition to answers
1) 将 UIScrollViewDelegate 添加到 UIPageViewController
extension PageViewController: UIScrollViewDelegate
2) 添加到 viewDidLoad
for view in self.view.subviews
if let scrollView = view as? UIScrollView
scrollView.delegate = self
3) 添加 UIScrollViewDelegate 方法
func scrollViewDidScroll(scrollView: UIScrollView)
if currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
else if currentIndex == totalViewControllers - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)
if currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
else if currentIndex == totalViewControllers - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
【讨论】：
很好用，你只需要正确设置 currentIndex ！ 一开始我不确定如何正确设置索引，最后做了我在答案中发布的内容，如果你想包含我可以删除 @BalázsPapp ，完全同意你的看法。 @BalázsPapp 你是如何正确设置 currentIndex 的？ 查看这篇文章以在UIPageViewController***.com/questions/8400870/…中找到currentIndex【参考方案3】：
唯一可行的解决方案，2020 年
以下是一个完整的解决方案，与其他答案不同，它不需要您编写/测试自己的代码来跟踪当前显示页面的索引。
假设您的页面存储在sourcePageViewControllers 不可变数组中，并且在您将UIPageViewController 创建为myPageViewController 之后：
let scrollView = myPageViewController.view.subviews.compactMap( $0 as? UIScrollView ).first!
scrollView.delegate = <instance of YourScrollViewDelegateClass>
然后：
extension YourScrollViewDelegateClass: UIScrollViewDelegate
func scrollViewDidScroll(_ scrollView: UIScrollView)
guard sourcePageViewControllers.count > 1 else
scrollView.isScrollEnabled = false
return
guard let viewControllers = myPageViewController.viewControllers, viewControllers.count != 0 else return
let baseRecord =
viewControllers
.map [superview = myPageViewController.view!] viewController -> (viewController: UIViewController, originX: CGFloat) in
let originX = superview.convert(viewController.view.bounds.origin, from: viewController.view).x
return (viewController: viewController, originX: originX)
.sorted(by: $0.originX < $1.originX )
.first!
guard let baseIndex = sourcePageViewControllers.firstIndex(of: baseRecord.viewController) else return
let baseViewControllerOffsetXRatio = -baseRecord.originX/scrollView.bounds.width
let progress = (CGFloat(baseIndex) + baseViewControllerOffsetXRatio)/CGFloat(sourcePageViewControllers.count - 1)
if !(0...1 ~= progress)
scrollView.isScrollEnabled = false
scrollView.isScrollEnabled = true
【讨论】：
【参考方案4】：如果您跟踪您的 currentIndex，那么以下内容应该就足够了，但它有点错误，因为有一个随机场景会完全停止滚动。
我认为 scrollView.bounces 有点错误，也许我遗漏了一些东西，因为大多数情况下它都可以正常工作，如果有人能够根据以下内容提供解决方案，那就太好了。
public func scrollViewDidScroll(_ scrollView: UIScrollView)
scrollView.bounces = currentIndex == 0 ||
currentIndex == controllers.count - 1
? false
: true
【讨论】：
【参考方案5】：我不确定如何正确管理currentIndex，但最终还是做了
extension Main: UIPageViewControllerDelegate
func pageViewController(pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool)
if completed
guard let viewController = pageViewController.viewControllers?.first,
index = viewControllerDatasource.indexOf(viewController) else
fatalError("Can't prevent bounce if there's not an index")
currentIndex = index
【讨论】：
当前索引？问题是关于防止反弹 @ZaporozhchenkoAleksandr 如果不使用当前索引，您将无法防止反弹【参考方案6】：另一个选项是设置 ScrollView.bounce = false。 它解决了我的 pageViewController（当然不是关于 ScrollView）滚动反弹的问题。 弹跳被禁用，所有页面都可以滚动而不会弹跳。
【讨论】：
这是错误的建议——如果 UIPageViewController 的滚动视图禁用了弹跳，它就会停止水平分页。【参考方案7】：@Dong Ma 的方法很完美，但可以稍微改进和简化。
要放入 viewDidLoad 的代码：
for subview in view.subviews
if let scrollView = subview as? UIScrollView
scrollView.delegate = self
break
scrollViewDidScroll的实现：
public func scrollViewDidScroll(_ scrollView: UIScrollView)
if (currentPage == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width) || (currentPage == totalNumberOfPages - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width)
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
scrollViewWillEndDragging的实现：
public func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)
if (currentPage == 0 && scrollView.contentOffset.x <= scrollView.bounds.size.width) || (currentPage == totalNumberOfPages - 1 && scrollView.contentOffset.x >= scrollView.bounds.size.width)
targetContentOffset.pointee = CGPoint(x: scrollView.bounds.size.width, y: 0)

【参考方案8】：东马的编辑答案，其中：
添加 - 尊重布局方向（例如希伯来语） 已修复 - 快速滑动时错误计数currentIndex
信息：
用 Swift 5.0 编写 在 Xcode 10.2.1 中构建和测试 ios 12.0如何：
-
假设我们有一个
UIViewController，其中UIPageViewController 添加为子VC。
class ViewController: UIViewController
var pageNavigationController: UIPageViewController!
private var lastPosition: CGFloat
private var nextIndex: Int
var currentIndex: Int
// rest of UI's setups
-
将
ViewController设置为UIPageViewController的代表：
extension ViewController: UIPageViewControllerDataSource
func pageViewController(_ pageViewController: UIPageViewController, willTransitionTo pendingViewControllers: [UIViewController])
guard
let currentVisibleViewController = pageViewController.viewControllers?.first,
let nextIndex = pageViewControllers.firstIndex(of: currentVisibleViewController)
else
return
self.nextIndex = nextIndex
func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool)
if completed, let currentVisibleViewController = pageViewController.viewControllers?.first, let newIndex = pageViewControllers.firstIndex(of: currentVisibleViewController)
self.currentIndex = newIndex
self.nextIndex = self.currentIndex
-
设置
ViewController为UIPageController的数据源：
extension ViewController: UIPageViewControllerDataSource
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController?
// provide next VC
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController?
// provide prev VC
// IMPORTANT: that's the key why it works, don't forget to add it
func presentationIndex(for pageViewController: UIPageViewController) -> Int
return currentIndex
-
通过将
ViewController 设置为UIPageViewController 的UIScrollView 的代表来“禁用”弹跳：
// MARK: - UIScrollViewDelegate (disable bouncing for UIPageViewController)
extension BasePaginationVC: UIScrollViewDelegate
func attachScrollViewDelegate()
for subview in pageNavigationController.view.subviews
if let scrollView = subview as? UIScrollView
scrollView.delegate = self
lastPosition = scrollView.contentOffset.x
break
func scrollViewDidScroll(_ scrollView: UIScrollView)
switch UIView.userInterfaceLayoutDirection(for: view.semanticContentAttribute)
case .leftToRight:
if nextIndex > currentIndex
if scrollView.contentOffset.x < (lastPosition - (0.9 * scrollView.bounds.size.width))
currentIndex = nextIndex
else
if scrollView.contentOffset.x > (lastPosition + (0.9 * scrollView.bounds.size.width))
currentIndex = nextIndex
if currentIndex == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)
else if currentIndex == pageViewControllers.count - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0)

【参考方案9】：我在 Swift 5 中的解决方案
在我的场景中，我首先在第二页加载UIPageViewController。我一共有三页，所以我打开中间的那一页。
这是我的UIPageViewController的代码
import UIKit
class MainPageViewController: UIPageViewController, UIPageViewControllerDataSource, UIPageViewControllerDelegate, UIScrollViewDelegate
let idList = ["OverviewController", "ImportantItemsController", "ListMenuController"] // A list of all of my viewControllers' storyboard id
var currentPage = 1 // Tracking the current page
override func viewDidLoad()
super.viewDidLoad()
setupPageController()
for subview in self.view.subviews // Getting the scrollView
if let scrollView = subview as? UIScrollView
scrollView.delegate = self
break;
// UIPageViewControllerDataSource
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController?
let index = idList.firstIndex(of: viewController.restorationIdentifier!)!
if (index > 0)
return storyboard?.instantiateViewController(withIdentifier: idList[index - 1])
return nil
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController?
let index = idList.firstIndex(of: viewController.restorationIdentifier!)!
if (index < idList.count - 1)
return storyboard?.instantiateViewController(withIdentifier: idList[index + 1])
return nil
func presentationCount(for pageViewController: UIPageViewController) -> Int
return idList.count
// UIPageViewControllerDelegate
func pageViewController(_ pageViewController: UIPageViewController, didFinishAnimating finished: Bool, previousViewControllers: [UIViewController], transitionCompleted completed: Bool)
if completed
guard let vc = pageViewController.viewControllers?.first else return
switch vc
case is ImportantItemsController:
currentPage = 1
case is OverviewController:
currentPage = 0
default:
currentPage = 2
// ScrollViewDelegate
func scrollViewDidScroll(_ scrollView: UIScrollView)
let totalViewControllersInPageController = idList.count
if (currentPage == 0 && scrollView.contentOffset.x < scrollView.bounds.size.width)
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0);
else if (currentPage == totalViewControllersInPageController - 1 && scrollView.contentOffset.x > scrollView.bounds.size.width)
scrollView.contentOffset = CGPoint(x: scrollView.bounds.size.width, y: 0);
func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)
let totalViewControllersInPageController = idList.count
if (currentPage == 0 && scrollView.contentOffset.x <= scrollView.bounds.size.width)
targetContentOffset.pointee = CGPoint(x: scrollView.bounds.size.width, y: 0);
else if (currentPage == totalViewControllersInPageController - 1 && scrollView.contentOffset.x >= scrollView.bounds.size.width)
targetContentOffset.pointee = CGPoint(x: scrollView.bounds.size.width, y: 0);
fileprivate func setupPageController()
let controller = storyboard?.instantiateViewController(withIdentifier: idList[1]) as! ImportantItemsController // Loading on the second viewController
setViewControllers([controller], direction: .forward, animated: true, completion: nil)
dataSource = self
delegate = self
【讨论】：
【参考方案10】：如果您希望完全禁用 UIPageViewController 子类上的滚动视图，您可以使用下面的 sn-p。请注意，这不仅会禁用弹跳，还会禁用页面的水平滚动。
在我的情况下，我有一个 UISegmentedControl 在 PageViewController 中的页面之间切换，因此禁用垂直滚动完全没问题，并且对我有用。希望对其他人也有帮助。
class MyPageViewController: UIPageViewController
private lazy var scrollView: UIScrollView = view.subviews.compactMap( $0 as? UIScrollView ).first! ()
override func viewDidLoad()
super.viewDidLoad()
scrollView.isScrollEnabled = false
【讨论】：
【参考方案11】：UIPageViewController 实际上并没有为您做太多事情。您可以很容易地将 UIScrollView 与视图控制器一起使用，并在其上禁用反弹。
只是做一些类似的事情
int x=0;
for (NSString *storyboardID in storyboardIDs)
UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:storyboardID];
[self addChildViewController:vc];
vc.view.frame = CGRectMake(x++*vc.view.frame.size.width, 0, vc.view.frame.size.width, vc.view.frame.size.height);
[self.scrollView addSubview:vc.view];
[vc didMoveToParentViewController:self];
self.scrollView.contentSize = CGSizeMake(storyboardIDs.count*vc.view.frame.size.width, vc.view.frame.size.height);
【讨论】：
真的！ UIPageViewController 使事情变得更加复杂，我能看到的基本用法的唯一优势是 Page Curl 效果的实现比 UIScrollView 更容易。并不是说它是大约 10 行代码，而页面控制器是 100 行：)【参考方案12】：如果您尝试禁用UIPageViewController.scrollView 的弹跳，您肯定会得到一个损坏的pageViewController：滑动不起作用。所以，不要那样做：
self.theScrollView.alwaysBounceHorizontal = NO;
self.theScrollView.bounces = NO;
使用在UIPageViewController 子视图中搜索scrollView 引用的解决方案仅用于完全禁用滚动：
@interface MyPageViewController : UIPageViewController
@property (nonatomic, assign) BOOL scrollEnabled;
@end
@interface MyPageViewController ()
@property (nonatomic, weak) UIScrollView *theScrollView;
@end
@implementation MyPageViewController
- (void)viewDidLoad
[super viewDidLoad];
for (UIView *view in self.view.subviews)
if ([view isKindOfClass:UIScrollView.class])
self.theScrollView = (UIScrollView *)view;
break;
- (void)setScrollEnabled:(BOOL)scrollEnabled
_scrollEnabled = scrollEnabled;
self.theScrollView.scrollEnabled = scrollEnabled;
@end
在 UIPageViewController 禁用弹跳的解决方案：
-
创建
UIScrollView 类别（例如CustomScrolling）。 UIScrollView 已经是他们的手势识别器的代表了。
请注意，您的目标UIViewController（又名baseVC，内部带有UIPageViewController）通过AppDelegate 共享。否则，您可以使用运行时 (#import <objc/runtime.h>) 并将引用属性（到您的控制器 baseVC）添加到类别中。
实现类别：
@interface UIScrollView (CustomScrolling) <UIGestureRecognizerDelegate>
@end
@implementation UIScrollView (CustomScrolling)
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
UIViewController * baseVC = [(AppDelegate *)[[UIApplication sharedApplication] delegate] baseVC];
if (gestureRecognizer.view == baseVC.pageViewController.theScrollView)
NSInteger page = [baseVC selectedIndex];
NSInteger total = [baseVC viewControllers].count;
UIPanGestureRecognizer *recognizer = (UIPanGestureRecognizer *)gestureRecognizer;
CGPoint velocity = [recognizer velocityInView:self];
BOOL horizontalSwipe = fabs(velocity.x) > fabs(velocity.y);
if (!horizontalSwipe)
return YES;
BOOL scrollingFromLeftToRight = velocity.x > 0;
if ((scrollingFromLeftToRight && page > 0) || (!scrollingFromLeftToRight && page < (total - 1)))
return YES;
return NO;
return YES;
@end
在您的baseVC 中导入类别文件#import "UIScrollView+CustomScrolling.h"，该文件使用UIPageViewController。
【讨论】：
你能和全班分享一个要点吗？ @el.severo 其实我已经做到了。只有一个弱点：在UIScrollView (CustomScrolling) 类别中获取指向baseVC 的指针。【参考方案13】：
这在viewDidLoad 中对我有用：
for subview in pager.view.subviews
if let scrollView = subview as? UIScrollView
scrollView.bounces = false
scrollView.alwaysBounceHorizontal = false
break
【讨论】：
【参考方案14】：编辑：不要使用此解决方案。留在这里用于参考和教育目的我后来了解到，这会引入一个错误，其中大约 5% 的时间，用户无法在同一方向上翻页。他们必须向后翻页，然后再向前继续。
如果您使用的是UIPageViewControllerDataSource，一个相对简单的解决方法（并且有点老套）是在每次调用pageViewController:viewControllerBeforeViewController: 委托方法时禁用弹跳。这是一个示例实现：
@interface YourDataSourceObject ()
@property (strong, nonatomic) UIScrollView *scrollView;
@end
@implementation
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
if (!self.scrollView)
for (UIView *view in pageViewController.view.subviews)
if ([view isKindOfClass:[UIScrollView class]])
self.scrollView = (UIScrollView *)view;
self.scrollView.bounces = NO;
// Your other logic to return the correct view controller.
@end
【讨论】：
您发布了“不要使用此解决方案”。为什么不简单地删除这个答案？你不会因此而失去任何分数。 @MichaelDautermann 我会把它留在这里。出于教育目的，看到不良模式也很好。由于 SO 就像一本巨大的去中心化手册，它很有价值 ;) 反弹 = NO 根本不起作用。它只是停止滚动。以上是关于禁用 UIPageViewController 反弹的主要内容，如果未能解决你的问题，请参考以下文章
