From the unity iphone manual:
You can save required files to a Documents folder next to your game's Data folder.
public static string GetiPhoneDocumentsPath ()
// Your game has read+write access to /var/mobile/Applications/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/Documents
// Application.dataPath returns
// Strip "/Data" from path
string path = Application.dataPath.Substring (0, Application.dataPath.Length - 5);
// Strip application name
path = path.Substring(0, path.LastIndexOf('/'));
return path + "/Documents";
You can Cache downloaded asset bundle using .NET file API and for reuse it in the future by loading it via WWW class
// Code designed for caching on iPhone, cachedAssetBundle path must be different when running in Editor
// See code snippet above for getting the path to your Documents folder
private var cachedAssetBundle : "path to your Documents folder" + "/savedassetbundle.assetbundle";
var cache = new System.IO.FileStream(cachedAssetBundle, System.IO.FileMode.Create);
cache.Write(download.bytes, 0, download.bytes.Length);
Debug.Log("Cache saved: " + cachedAssetBundle);
In short, yes you can save files on the iphone with the System.IO.FileStream
Great info, just saved ma few hours work :)
Since Unity3.3, Application.persistentDatapath can be used, removing the need to edit the Application.dataPath string. More can be read here.

If you place a "Using" statement in the beginning/top of your .net/mono files you can remove the long paths eg. System.IO.FileStream can be shortned to FileStream

The API you want to use to get path to Documents folder of an App (where things can be persistently stored) is Application.persistentDataPath.

how can i delete saved data which i stored at persistent data path from the application ? can anyone suggest ?
Do you know the file's location? If you placed a file at a path like Path.Combine(Application.persistentDataPath, "myFile"), you could also check File.Exists() with that path, or call File.Delete() with that path to remove the file.
thank you rutter. works fine !
