WebView postMessage do not work on iOS

[magicismight]

postMessage to WebView can not work on iOS.

First, postMessage on react-native

this.refs.webview.postMessage("any thing");

Then receive the message on WebView side, the event is always {"isTrusted": false}

  document.addEventListener('message', function (e) {
   // e.data !== 'any thing'
   // e == {isTrusted: false}
  })

Additional Information

• React Native version: 0.41.0
• Platform: iOS
• Operating System: MacOS

@magicismight - How did you resolve this? I'm seeing the same thing {"isTrusted":false}

@rgoldiez Everything goes fine.
You can not print the event object directly.

  document.addEventListener('message', function (e) {
    console.log(e); // This will print {isTrusted: false}
    console.log(e.data); // This will work.
  })
