Nativescript + iOS webview +本地文件

Question

I'm currently working in a simple app, which has a HTML section which uses a webview.

The contents are in an app/www folder, and I access them from a "home.ts" component with something like this in the HTML

<GridLayout
    class="main-layout"
    columns="*"
    rows="*"
>
    <WebView
        src="~/www/index.html"
        class="web-view"
        col="0"
        id="wv"
        row="0"
    ></WebView>
</GridLayout>

This file uses a few images, some JS and some CSS.

It works fine on Android, but I can't make it work on iOS. Oh, and it works fine on the iOS emulator, but not in an actual device (I currently have a iOS 9 iPod touch for testing these things).

I have the correct keys configured on Info.plist (it works with URLs as https://www.google.com ), and I think I'm not doing anything weird.

This is my package.json

It's a known bug for local pages, it's not able to determine what ~ means in terms of filesystem you need to change the src in your code and figure out what ~refers to.

using :

import * as fs from "tns-core-modules/file-system";
public webViewSRC: string = encodeURI(`${fs.knownFolders.currentApp().path}/www/index.html`);
