ScrollView不能全屏的问题（问题已自己解决，进来的第一个送分了）_uiscrollview pagingenabled 之后不是全屏-优快云博客

本文介绍如何在SwiftUI应用中实现ScrollView的嵌套使用，并通过代码示例展示了如何设置背景颜色、禁用滚动指示器等特性，以及如何在每个页面中添加可缩放的子ScrollView。



@IBOutlet weak var E_ManualScrollView: UIScrollView!

func setScrollView(){

        E_ManualScrollView.backgroundColor = UIColor.redColor()

        E_ManualScrollView.pagingEnabled = true

        E_ManualScrollView.showsHorizontalScrollIndicator = false

        E_ManualScrollView.showsVerticalScrollIndicator = false

        E_ManualScrollView.scrollsToTop = false

        E_ManualScrollView.bounces = false

        E_ManualScrollView.contentOffset = CGPointZero

        // 将 scrollView 的 contentSize 设为屏幕宽度的8倍(根据实际情况改变)

        E_ManualScrollView.contentSize = CGSize(width: self.view.bounds.size.width * CGFloat(numOfPages), height: E_ManualScrollView.bounds.height)

        

        E_ManualScrollView.delegate = self

        for index  in 0..<numOfPages {

            

            let doubleTap = UITapGestureRecognizer(target: self, action: "handleDoubleTap:")

            doubleTap.numberOfTapsRequired = 2

            

            let zoomScrollView = UIScrollView(frame: CGRectMake(self.view.bounds.size.width * CGFloat(index), 0, self.view.bounds.size.width, E_ManualScrollView.bounds.height))

//            zoomScrollView.backgroundColor = self.E_ManualScrollView.backgroundColor

            zoomScrollView.backgroundColor = UIColor.yellowColor()

            zoomScrollView.contentOffset = self.E_ManualScrollView.contentOffset

            zoomScrollView.showsHorizontalScrollIndicator = false

            zoomScrollView.showsVerticalScrollIndicator = false

            zoomScrollView.contentSize = CGSize(width: self.view.bounds.size.width, height: E_ManualScrollView.bounds.height);

            zoomScrollView.delegate = self;

            zoomScrollView.minimumZoomScale = 1.0;

            zoomScrollView.maximumZoomScale = 3.0;

            //        zoomScrollCiew.tag = i+1;

            zoomScrollView.setZoomScale(1.0, animated: true)

            

            let imageView = UIImageView(image: UIImage(named: "cleaner_e_manual_0\(index + 1)"))

            imageView.contentMode = UIViewContentMode.ScaleAspectFit

            //超过frame的区域不显示在屏幕上

            imageView.clipsToBounds  = true;

            //自动调整view的高度，以保证上边距和下边距不变

            imageView.autoresizingMask = UIViewAutoresizing.FlexibleHeight

            imageView.frame = CGRect(x: 0, y: 0, width: self.view.bounds.size.width, height: E_ManualScrollView.bounds.height)

            imageView.userInteractionEnabled = true;

            imageView.addGestureRecognizer(doubleTap)

            

            zoomScrollCiew.addSubview(imageView)

            self.E_ManualScrollView.addSubview(zoomScrollView)

        }

        

        self.view.insertSubview(E_ManualScrollView, atIndex: 0)

    }
