ios - 自动水平滚动

Question

我应该怎么做才能像应用商店一样自动水平滚动？

会有一堆图像。这些图像有一些延迟出现在屏幕上并移出屏幕，这会无限重复，就像应用程序商店一样。

Answer 1

你可以用这个

将此添加到您的 pod 文件中

   pod 'Auk', '~> 7.0'

运行 pod 安装

  import UIKit
  struct DemoConstants {



 static let button = DemoConstantsButton()
 static let initialImage = (
    fileName: "slider1.jpg",
    description: " demo"
)
static let localImages = [
    (
        fileName: "image1.jpg",
        description: "Hotel Nirvana"
    ),
    (
        fileName: "image2.jpg",
        description: "Hotel Nirvana"
    ),
    (
        fileName: "image3.jpg",
        description: "demo2"
    ),
    (
        fileName: "image4.jpg",
        description: "demo3"
    ),

    (
        fileName: "image5.jpg",
        description: "demo4"
    ),
    (
        fileName: "image6.jpg",
        description: "demo5"
    )]
    }


    struct DemoConstantsButton {
    let borderWidth: CGFloat = 2
    let cornerRadius: CGFloat = 20
    let borderColor = UIColor.white
    }

在你的 View Controller 中

   import Auk

添加委托(delegate) UIScrollViewDelegate

    class yourViewController: UIViewController ,UIScrollViewDelegate 

拿一个 UIScrollView 做一个 outlet

           @IBOutlet weak var scrollView: UIScrollView!

在viewDidLoad中

      scrollView.delegate = self
        for localImage in DemoConstants.localImages {


        if let image = UIImage(named: localImage.fileName) {
            scrollView.auk.show(image: image)
      }}





    let pageIndex = scrollView.auk.currentPageIndex
    print(pageIndex!)



    scrollView.auk.settings.contentMode = UIViewContentMode.scaleAspectFill
    scrollView.auk.settings.pagingEnabled = true
    self.scrollView.auk.settings.pageControl.backgroundColor = UIColor.black
    scrollView.auk.startAutoScroll(delaySeconds: 3)
    scrollView.auk.scrollToPage(atIndex: 2, animated: true)
