How to disable scrolling entirely in a WKWebView?

Question

I know this looks like a simple question one can simply say:

webview.scrollView.scrollEnabled = NO;
webview.scrollView.panGestureRecognizer.enabled = NO;
web         


        

Answer 1

I found that I had to make my view controller a UIScrollViewDelegate then add this function to prevent scrolling.

func scrollViewDidScroll(_ scrollView: UIScrollView) {
   scrollView.setContentOffset(CGPoint(x: 0, y: 0), animated: false)
}

Answer 2

Before Swift 3

You can simply disable scroll on its implicit scrollView

webView.scrollView.scrollEnabled = false

Swift 3

webView.scrollView.isScrollEnabled = false

Answer 3

Try to disable scrollView zoom in this way:

CGFloat zoomScale = webview.scrollView.zoomScale;
webview.scrollView.maximumZoomScale = zoomScale;
webview.scrollView.minimumZoomScale = zoomScale;

Credit and many thanks to apouche for the Obj-C code. In case anybody else has the same problem, here is the working solution adapted for Swift 2

extension WKWebView {

  func setScrollEnabled(enabled: Bool) {
    self.scrollView.scrollEnabled = enabled
    self.scrollView.panGestureRecognizer.enabled = enabled
    self.scrollView.bounces = enabled

    for subview in self.subviews {
        if let subview = subview as? UIScrollView {
            subview.scrollEnabled = enabled
            subview.bounces = enabled
            subview.panGestureRecognizer.enabled = enabled
        }

        for subScrollView in subview.subviews {
            if subScrollView.dynamicType == NSClassFromString("WKContentView")! {
                for gesture in subScrollView.gestureRecognizers! {
                    subScrollView.removeGestureRecognizer(gesture)
                }
            }
        }
    }
  }
}

Here is a Swift 3 version:

extension WKWebView {

    func setScrollEnabled(enabled: Bool) {
        self.scrollView.isScrollEnabled = enabled
        self.scrollView.panGestureRecognizer.isEnabled = enabled
        self.scrollView.bounces = enabled

        for subview in self.subviews {
            if let subview = subview as? UIScrollView {
                subview.isScrollEnabled = enabled
                subview.bounces = enabled
                subview.panGestureRecognizer.isEnabled = enabled
            }

            for subScrollView in subview.subviews {
                if type(of: subScrollView) == NSClassFromString("WKContentView")! {
                    for gesture in subScrollView.gestureRecognizers! {
                        subScrollView.removeGestureRecognizer(gesture)
                    }
                }
            }
        }
    }
}
