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.

(apparently html-style hyperlinks don't work in the comments 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

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 !

The API you want to use to get path to Documents folder of an App (where things can be persistently stored) is Application.persistentDataPath.
Up to 2 attachments (including images) can be used with a maximum of 524.3 kB each and 1.0 MB total.
