Unity中内嵌网页插件UniWebView

一、常见Unity中内嵌网页实现方式：

1、UnityWebCore只支持windows

2、Unity-Webview支持Android，IOS

3、UniWebView支持mac os，Android，IOS，WP8（2.0以后）

二、UniWebView 根据手机平台调用相应的WebView组件来显示网页，支持和javascript的交互，不支持windows和editor上显示。

1、下载并导入unitypackage

http://uniwebview.onevcat.com/

2、设置Webview，加载并显示网页

// Find the UniWebView component on the gameObject.
// It is supposed you have already dragged this script to the same gameObject which UniWebView on.
// Or you will get a null exception :(
_webView = GetComponent<UniWebView>();
 
// Listen to some event of UniWebView
_webView.OnLoadComplete += OnLoadComplete;
_webView.OnReceivedMessage += OnReceivedMessage;
_webView.OnEvalJavaScriptFinished += OnEvalJavaScriptFinished;

// Almost full screen but 5 points gap in each edge.
_webView.insets = new UniWebViewEdgeInsets(5,5,5,5);
// Set a url string to load
_webView.url = "http://uniwebview.onevcat.com/demo/index.html";

// Tell the web view begin to load the url just set.
_webView.Load();
 
// Then wait for the OnLoadComplete event
 
//...
 
// The listening method of OnLoadComplete method.
void OnLoadComplete(UniWebView webView, bool success, string errorMessage) {
  if (success) {
    // Great, everything goes well. Show the web view now.
    webView.Show();
  } else {
    // Oops, something wrong.
    Debug.LogError("Something wrong in web view loading: " + errorMessage);
  }
}

3、网址解析

uniwebview://move?direction=up&distance=1会解析成

path = "move"
args = {
    direction = "up",
    distance = "1"
}

4、监听消息

void OnReceivedMessage(UniWebView webView, UniWebViewMessage message) {
   Debug.Log(message.rawMessage);
   if (string.Equals(message.path, "move")) {
      // It is time to move!
 
      // In this example:
      // message.args["direction"] = "up"
      // message.args["distance"] = "1"
   }
}
