Question by ChuckSaldana · Feb 10, 2011 at 09:33 PM · iphonepathfile-io

iPhone System.IO.File.Exists() not working

The following instruction checks if the file at path exists:

string path = GetiPhoneDocumentsPath();
if (System.IO.File.Exists(path) == false) XmlTextWriter textWriter = new XmlTextWriter(path,null);

Then if the file does not exists it creates a new one, it all works well in unity execution, but when I execute the program in iphone, the file is never created.

Here's the function to obtain the path:

public static string GetiPhoneDocumentsPath () { 
        // Your game has read+write access to /var/mobile/Applications/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/Documents 
        // Application.dataPath returns              
        // /var/mobile/Applications/XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX/myappname.app/Data 
        // 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/myFile.xml";  
    }

I'm pretty sure you have to use 'Application.persistentDataPath' by the way...

Got it!

    FileInfo info = new FileInfo(path);
    if (info == null || info.Exists == false) { ... };
