Get HTML native, the display is being proven in webView. Each time the slider worth adjustments, I need to change the font measurement of webView via webview.valueJavaScript, however there are adjustments, which isn’t what I would like. Are you aware tips on how to clear up this downside?
func makeUIView(context: Context) -> WKWebView {
...
let script = WKUserScript(supply: "doc.physique.type.fontSize = "(Int(worth))px";", injectionTime: .atDocumentEnd, forMainFrameOnly: true)
contentController.addUserScript(script)
...
}
I attempted to alter the script by registering it, however the font measurement solely modified at first, but it surely did not change afterwards.
