You will have to add maximum scale in script.

The following code should help you:

<pre><code>let source: String = "var meta = document.createElement('meta');" +
 "meta.name = 'viewport';" +
 "meta.content = 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no';" +
 "var head = document.getElementsByTagName('head')[0];" +
 "head.appendChild(meta);"

let script: WKUserScript = WKUserScript(source: source, injectionTime: .atDocumentEnd, forMainFrameOnly: true)
let userContentController: WKUserContentController = WKUserContentController()
let conf = WKWebViewConfiguration()
conf.userContentController = userContentController
userContentController.addUserScript(script)
let webView = WKWebView(frame: CGRect.zero, configuration: conf)
</code></pre>

OK this is how I solved this:

<pre><code>wkWebView.configuration.userContentController.addUserScript(self.getZoomDisableScript()) 

private func getZoomDisableScript() -&gt; WKUserScript {
 let source: String = "var meta = document.createElement('meta');" +
 "meta.name = 'viewport';" +
 "meta.content = 'width=device-width, initial-scale=1.0, maximum- scale=1.0, user-scalable=no';" +
 "var head = document.getElementsByTagName('head')[0];" + "head.appendChild(meta);"
 return WKUserScript(source: source, injectionTime: .atDocumentEnd, forMainFrameOnly: true)
} 
</code></pre>

it's works on iOS 13

<pre><code>NSString *javascript = @"var meta = document.createElement('meta');meta.setAttribute('name', 'viewport');meta.setAttribute('content', 'width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no');document.getElementsByTagName('head')[0].appendChild(meta);";
// you should use WKUserScript, `evaluateJavaScript` is not working
WKUserScript *us = [[WKUserScript alloc] initWithSource:javascript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES];[wkWebView.configuration.userContentController addUserScript:us];
</code></pre>

not working

<pre><code>- (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {
 return nil;
}

- (void)scrollViewWillBeginZooming:(UIScrollView *)scrollView withView:(UIView *)view {
 scrollView.pinchGestureRecognizer.enabled = NO;
}

</code></pre>

blocks|key|4846375|text|无法找到一种通过双击完全禁用缩放的适当方法，但这里有一个解决方案，对于我的用例来说已经足够了：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4846376|private+var+zoomScale:+CGFloat?+=+nil

Couldn't find a proper way to completely disable zooming by double tap, but here's a workaround that's sufficient for my use case:
<pre><code>private var zoomScale: CGFloat? = nil

func scrollViewWillBeginZooming(_ scrollView: UIScrollView, with view: UIView?) {
 zoomScale = scrollView.zoomScale

 // And use the same solution to prevent pinch to zoom as in other answers
 scrollView.pinchGestureRecognizer?.isEnabled = false
}
 
func scrollViewDidZoom(_ scrollView: UIScrollView) {
 if let originalScale = zoomScale {
 scrollView.zoomScale = originalScale
 }
}
</code></pre>
It simply stores the zoomScale before the zooming begins, and then resets it immediately after it finishes, resulting in just a little movement.

Does anyone know a nice simple way to disable double-click and pinch zooming in a WKWebView? Nothing I've tried works:

<pre><code>Webview.scrollView.allowsMagnification = false; // Error: value of type WKWebView has no member allowsMagnification

Webview.scrollView.isMultipleTouchEnabled = false; // doesn't do anything
</code></pre>

In the html:

<pre><code>&lt;meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" /&gt; // pile of crap, does nothing
</code></pre>

Disable zoom in WKWebView?
