InkPageIndicator是一个美丽的UIPageControl

特性

• 支持RxSwift
• 快速滚动时的时序问题

安装

CocoaPods

InkPageIndicator通过CocoaPods提供。要安装它，只需将以下行添加到Podfile

pod 'InkPageIndicator'

Carthage

Carthage是一个支持多种平台的依赖项管理器。它用于构建依赖项并提供二进制框架。

要通过Carthage将InkPageIndicator集成到您的Xcode项目中，请在您的Cartfile中指定它

github "InkPageIndicator/InkPageIndicator"

运行carthage update以构建框架，然后将构建的InkPageIndicator.framework拖入您的Xcode项目

在应用程序目标的“编译阶段”设置标签页上，单击“+”图标，选择“新运行脚本阶段”，并添加如Carthage入门步骤4、5和6中所述的框架路径

手动

• 打开终端，进入您的顶级项目目录，并运行以下命令

pod install --repo-update
open InkPageIndicator.xcworkspace

用法

AssinPageControl

pageControl.pageIndicatorTintColor = UIColor.lightGray
pageControl.numberOfPages = pages.count
pageControl.currentPage = 1
pageControl.currentPageIndicatorTintColor = UIColor.black
pageControl.dotSize = CGSize(width: 10, height: 10)
pageControl.spacing = 20

适用于 UIPageViewController

YourUIViewController

实现 WrapInkPageControlAdapter 协议

class YourUIViewController: UIViewController, WrapInkPageControlAdapter {
private lazy var pageContoller: AssinPageController = {
   return pageControl
}()

并将适配器设置为 YourUIPageViewController

page.adapter = self

YourUIPageViewController

启用滑动手势并注册滚动视图的代理，要启用滑动手势，YourUIPageViewController 需要遵循 UIPageViewPageable

class YourUIPageViewController: UIPageViewController, UIPageViewPageable

override func viewDidLoad() {
   super.viewDidLoad()
   self.enableSwipeGesture(self)
   self.scrollView?.delegate = self
}

实现 InkPagePageViewBridge 协议

extension YourUIPageViewController: InkPagePageViewBridge {
   func pageFirstIndex(viewControllers:) -> Int? {
    }
    
    var itemCount: Int {
    }
}

实现 UIPageViewControllerDelegate 协议，并调用以下函数

extension YourUIPageViewController: UIPageViewControllerDelegate {
    func pageViewController(_:willTransitionTo:) {
        self.behavior.pageViewController(pageViewController, willTransitionTo: pendingViewControllers)
    }
    func pageViewController(_: didFinishAnimating:previousViewControllers:transitionCompleted:) {
        self.behavior.pageViewController(
            pageViewController,
            didFinishAnimating: finished,
            previousViewControllers: previousViewControllers,
            transitionCompleted: completed
        )
    }
}

在您的 YourUIPageViewController 中声明一个变量

private lazy var behavior = InkPageViewScrollingBehavior(self, adapter: self)

实现 UIScrollViewDelegate 协议

extension YourUIViewController: UIScrollViewDelegate {
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        self.behavior.scrollViewDidScroll(scrollView)
    }
}

针对 UICollectionView

实现 WrapInkPageControlAdapter 协议

class YourUIViewController: UIViewController, WrapInkPageControlAdapter {
private lazy var pageContoller: AssinPageController = {
   return pageControl
}()

在 'UIViewController' 中声明一个变量

private lazy var behavior = InkCollectionViewScrollingBehavior(self, adapter: self)

实现 InkPageCollectionViewBridge 协议

extension YourUIViewController: InkPageCollectionViewBridge {
    var itemCount: Int {
    }

    var itemWidth: CGFloat {
    }

    var contentOffset: CGPoint {
    }

    func scrollToItem(page: Int) {
    }
}

实现 UICollectionViewDelegateFlowLayout 协议，并调用以下代码的函数

extension UICollectionViewControllerExample: UICollectionViewDataSource {
    func scrollViewWillBeginDragging(_ scrollView: UIScrollView) {
        self.behavior.scrollViewWillBeginDragging(scrollView)
    }
    func scrollViewDidEndDragging(_ scrollView: UIScrollView, willDecelerate decelerate: Bool) {
        self.behavior.scrollViewDidEndDragging(scrollView, willDecelerate: decelerate)

    }
    func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
        self.behavior.scrollViewWillEndDragging(scrollView, withVelocity: velocity, targetContentOffset: targetContentOffset)
    }
    func scrollViewDidScroll(_ scrollView: UIScrollView) {
        self.behavior.scrollViewDidScroll(scrollView)
    }
}
