Load and save file. IOS problem
Hey,
I want to migrate my Unity game into IOS system, but I have a problem with load and save file.This is simple file with player high score. It work fine for the android but crash on the IOS. This is my code:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
public class GameMaster : MonoBehaviour {
PlayerData playerData = new PlayerData();
void Start () {
LoadPlayerData ();
}
public void SavePlayerData()
{
if ( score > playerData.highScore)
{
BinaryFormatter bf = new BinaryFormatter ();
FileStream file = File.Create (Application.persistentDataPath
+ "/playerInfo.dat");
playerData.highScore = score;
isHighScore = true;
bf.Serialize( file, playerData);
file.Close();
}
}
public void LoadPlayerData()
{
//Debug.Log ("Application.persistentDataPath: " + Application.persistentDataPath);
if (File.Exists (Application.persistentDataPath + "/playerInfo.dat"))
{
BinaryFormatter bf = new BinaryFormatter ();
FileStream file = File.Open( Application.persistentDataPath + "/playerInfo.dat", FileMode.Open);
playerData = (PlayerData)bf.Deserialize( file);
highScoreText.text = "High Score: " + playerData.highScore;
file.Close();
}
}
}
[System.Serializable]
class PlayerData
{
public int highScore = 0;
}
When I comment invoke of LoadPlayerData function in start() and SavePlayerData I don't have any bugs or crash on my iPhone but ofc. I can't load and save best score either. Do you know where is the problerm?
Thanks.
EDIT:
I put some Debug.log() into my Unity code in save and load function. And this is my xCode debug log:

I found similar problem with 'SerializationException: Unexpected binary element: 255' http://answers.unity3d.com/question...aryformatter-stopped-working.html?sort=oldest
I added:
void Awake()
{
// Forces a different code path in the BinaryFormatter that doesn't rely on run-time code generation (which would break on iOS).
Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER", "yes");
}
into file when I have LoadPlayerData() and SavePlayerData() Plus I deleted old version of my app form the iPhone before I compile new one in xCode. I thought it helped, but when I restart my app few time problem comes back.
