WWW can't work on the IOS, webplayer

Hi,

Following code can work on PC, but it can not work on my ios, webplayer.
unity3d version is 4.0 f7.
Who can tell me why?

thanks in advance

Code (csharp):

1.  
2. string web_erro = "abc";
3.  
4. void OnGUI () {
5.         if(GUI.Button(new Rect(100, 100, 100, 30), "get")) {
6.             url = "www.google.com";
7.             StartCoroutine(this.read_web(url));
8.         }
9.         GUI.Label(new Rect(100, 200, 200, 200), web_erro);
10.     }
11.    
12.     IEnumerator read_web(string url) {
13.         WWW data = new WWW(url);
14.         yield return data;
15.         if(data.isDone) {
16.             web_erro = data.text;
17.         }
18.         else {
19.             web_erro = data.error;
20.         }
21.     }
22.  

 

If you want proper error checking, replace data.isDone with String.IsNullOrEmpty(data.error)
http://docs.unity3d.com/Documentation/ScriptReference/WWW-error.html

And it also helps if you specify the protocol, so use http://www.google.com instead of www.google.com

 

Thank you very much！ The problem was lack of crossdomain.xml file.
