Save data through xml Serialization on iOS

Questions & Answers

Hey

I ran into a problem today testing my project on my iPhone the first time which seems to be connected to the xml Serialization (i think), as xCode tells me:

  • Completed reload, in 0.183 seconds
    → applicationDidBecomeActive()
    IsolatedStorageException: Could not find a part of the path “/var/mobile/Applications/FFC4693A-C632-4DE3-8324-4451DD39C1BC/FahrSimulator.app/Data/Resources/data.xml”.
    at System.IO.FileStream…ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options) [0x00000] in :0
    at System.IO.FileStream…ctor (System.String path, FileMode mode, FileAccess access, FileShare share) [0x00000] in :0
    at System.IO.StreamWriter…ctor (System.String path, Boolean append, System.Text.Encoding encoding, Int32 bufferSize) [0x00000] in :0
    at System.IO.StreamWriter…ctor (System.String path) [0x00000] in :0
    at MainMenuScript.Save () [0x00000] in :0
    at MainMenuScript.Start () [0x00000] in :0

So I already set my project to .net 2.0 subset. So I read smth about using the resources folder to get the data from there but I ran into a problem.

My code so fare is:

function Save()
{
var serializer : XmlSerializer = new XmlSerializer(typeof(PlayerScores));
var writer : System.IO.StreamWriter = new System.IO.StreamWriter(Application.dataPath + “/Resources/data.xml”);
serializer.Serialize(writer, player);
writer.Close();
}

function Load()
{
var serializer : XmlSerializer = new XmlSerializer(typeof(PlayerScores));
var reader : System.IO.StreamReader = new System.IO.StreamReader(Application.dataPath + “/Resources/data.xml”);
player = serializer.Deserialize(reader) as PlayerScores;
reader.Close();
}

I read smth about making the file a text file and calling it like this:

var textAsset : TextAsset = Resources.Load("/data", typeof(TextAsset));

But I’m not sure how to continue with that variable.

Could anybody fill in this variable in the script I posted a both? Or is there another problem/solution I have to face?

Best regards,

Fred

var textAsset : TextAsset = Resources.Load(“/data”, typeof(TextAsset));
var serializer : XmlSerializer = new XmlSerializer(typeof(PlayerScores));
var writer : System.IO.TextWriter = new System.IO.StreamWriter(textAsset.text); <— NullReferenceException
serializer.Serialize(writer, player);
writer.Close();

I tried to implement the textAsset like this but then I get a NullReferenceException. :frowning:
