WKWebView加载Html文件,如何自适应网页内容呢?就是不要让它左右滑动

WKWebView* webView = _realWebView;
        
        NSString *jScript = @"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);";
        
        if(scalesPageToFit)
        {
            WKUserScript *wkUScript = [[NSClassFromString(@"WKUserScript") alloc] initWithSource:jScript injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:NO];
            [webView.configuration.userContentController addUserScript:wkUScript];
        }
        else
        {
            NSMutableArray* array = [NSMutableArray arrayWithArray:webView.configuration.userContentController.userScripts];
            for (WKUserScript *wkUScript in array)
            {
                if([wkUScript.source isEqual:jScript])
                {
                    [array removeObject:wkUScript];
                    break;
                }
            }
            for (WKUserScript *wkUScript in array)
            {
                [webView.configuration.userContentController addUserScript:wkUScript];
            }
        }

webview.scalespagetofit只有UIWebView才有
