React Native WebView injectedJavaScript 报错window.postMessage

解决方案：

定义injectedJavaScript

(function() {

  var originalPostMessage = window.postMessage;

  var patchedPostMessage = function(message, targetOrigin, transfer) {

    originalPostMessage(message, targetOrigin, transfer);

  };

  patchedPostMessage.toString = function() {

    return String(Object.hasOwnProperty).replace('hasOwnProperty', 'postMessage');

  }; 

window.postMessage = patchedPostMessage;

})();

<WebView injectedJavaScript={patchPostMessageJsCode} /> 

这样就可以解决window.postMessage的问题了
