Application.persistentDataPath issues on iOS Device

Hello everyone,

I have been wrestling with a file access problem when writing to Application.persistentDataPath when running on an iOS device. I've tried to search feverishly both here and on Google and I have tried many solutions / suggestions but still get the same error. Here's the bit of code that I'm using to serialize and write an xml file:

Code (csharp):

1. public static bool SerializeObject<T>(string filename, T data)
2.     {
3.         string text="";
4.  
5.         try
6.         {
7.             XmlSerializer serializer = new XmlSerializer(typeof(T));
8.            
9.             using(var stream = new FileStream(Path.Combine(Application.persistentDataPath, filename), FileMode.Create, FileAccess.Write))
10.             {
11.                 serializer.Serialize(stream, data);
12.                 stream.Close();
13.             }
14.         }
15.         catch (System.Exception err)
16.         {
17.             text = err.ToString();
18.             inst.ShowErrorMsg(text);
19.             return false;
20.         }
21.  
22.         return true;
23.     }

And this is how I call it:

Code (csharp):

1. SerializeObject<SaveData>(Application.persistentDataPath + "\\" + saveFileName, tempData)

I get the unauthorizedexception:access .... is denied at System.IO.FileStream error. Any help would be tremendously appreciated!

Thanks!

 

Hrm...nevermind. I think I may have found my problem! Testing out the fix right now.

EDIT: Okay, confirmed fixed! The problem was, I was how I was passing in the "filename" parameter into SerializedObject. Simplifying my call to:

Code (csharp):

1. SerializeObject<SaveData>(saveFileName, tempData)
