Unity 使用UnityWebRequest 读取存档 （IOS只能这样做）

打IOS包的时候发现的，不能使用正常的IO流读取，不然会读取不到数据，只能使用UnityWebRequest 读取

代码如下

  public IEnumerator ReadArchive(Action<bool, string> ac, string filepath = ""){UnityWebRequest request = UnityWebRequest.Get(PathManger.PlatformSwitchingUrl(filepath));yield return request.SendWebRequest();var text = "";if (request.result == UnityWebRequest.Result.ConnectionError){DebugEX.Log("资源读取失败", request.error);}else{text = request.downloadHandler.text;DebugEX.Log("读取到的本地资源是", filepath, request.downloadHandler.text);}if (text == ""){m_CurrentArchiveVersion = NewestArchiveVersion;ac?.Invoke(false, null, fileType);}ac?.Invoke(true, payload, fileType);}}

使用协程读取 返回的数据就是string 读档内容
