禁用 webview 缩放 [英] Disabling zooming on webview

问题描述

我四处搜索，但找不到如何在 iOS 中禁用缩放功能.

I've searched around, but I couldn't find how to disable zooming in iOS.

我的 viewDidLoad() 中有这个，但它没有做任何事情.

I have this in my viewDidLoad() but it doesn't do anything.

webView.scrollView.isMultipleTouchEnabled = false;

有什么想法吗?

推荐答案

您可以在委托方法 didFinish navigation 中从 scrollView 中移除 pinchGestureRecognizer通过使您的 ViewController 符合 WKNavigationDelegate 如下，

You can remove the pinchGestureRecognizer from scrollView in delegate method didFinish navigation by conforming your ViewController to WKNavigationDelegate as below,

class ViewController: UIViewController, WKNavigationDelegate {

    var webView: WKWebView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // TODO: Initialize webView before setting the delegate
        webView.navigationDelegate = self
    }

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        if let pinchGesture = webView.scrollView.pinchGestureRecognizer {
            webView.scrollView.removeGestureRecognizer(pinchGesture)
        }
    }
}
