My app is working perfectly in android but in ios devices, app is unable to retrieve data from the file.
What could be the reasons for the following problem?
The android operating system knows what to do with the path you provide. iOS is far more picky.
Try escapeuristring.
WWW www = new WWW(System.Uri.EscapeUriString(“file://” + System.IO.Path.Combine(Application.persistantDataPath, fileName)));
