之前有网友询问这个问题， 当时我只是 提供了一个思路， 使用json序列化、反序列化。
下面就写出两种（都是只能变成字符串）
1、json的序列化、反序列化方式
JsonFx.Json.JsonReader.Deserialize(data);
JsonFx.Json.JsonWriter.Serialize(classObject);
使用了插件： JsonFx.dll
下面是使用的一个案例
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class DataManager : MonoBehaviour
{
//sets the different kind of data into the player prefs...
//sets the coins data(position and rotation)...
public void setCoinsData(GameObject coins)
{
int coinCounter = 0;
for (int i = 0; i < coins.transform.childCount; i++)
{
coinCounter++;
string key = coins.name + "" + coinCounter;
//Coins Tag,Position,Rotation are passed in the Constructor.
CoinsData coinData = new CoinsData(key, coins.transform.GetChild(i).position, coins.transform.GetChild(i).rotation);
//String data stores data
string data = JsonFx.Json.JsonWriter.Serialize(coinData);
// Finally storing my Data i.e parsed from jason parser in Player Prefs
PlayerPrefs.SetString(coins.tag + "" + coinCounter, data);
}
}
//gets the activated gold coins data(position and rotation)...
public GameObject getCoinsData()
{
GameObject coins = GameObject.FindGameObjectWithTag("Coin");
for (int i = 0; i < coins.transform.childCount; i++) { if (coinCounter > 0)
{
string data = PlayerPrefs.GetString(coins.tag + "" + coinCounter);
// Storing Vector3 Data in Jason.
CoinsData coinData = JsonFx.Json.JsonReader.Deserialize(data);
string key = coins.name + "" + coinCounter;
coinData.coinPositionData = coinData.data [key];
// Get Coin data.
coins.transform.GetChild(i).position = new Vector3(coinData.coinPositionData.position.x, coinData.coinPositionData.position.y, coinData.coinPositionData.position.z);
coins.transform.GetChild(i).rotation = new Quaternion(coinData.coinPositionData.rotation.x, coinData.coinPositionData.rotation.y, coinData.coinPositionData.rotation.z, coinData.coinPositionData.rotation.w);
coins.transform.GetChild(i).gameObject.SetActive(true);
coinCounter--;
} else
{
coins.transform.GetChild(i).gameObject.SetActive(false);
}
}
return coins;
}
class CoinsData
{
public PositionData coinPositionData = new PositionData();
// Storing Coin Data in Dictonary.
public Dictionary data = new Dictionary();
public CoinsData(string key, Vector3 coinPosition, Quaternion coinRotation)
{
// Get popstion of coin at run time
coinPositionData.position = new Cords(coinPosition.x, coinPosition.y, coinPosition.z);
coinPositionData.rotation = new Rotation(coinRotation.x, coinRotation.y, coinRotation.z, coinRotation.w);
// Add data to dictionary
if (key != null)
data.Add(key, coinPositionData);
}
// Default Constructer is needed when u r using Jason Parsing.
public CoinsData()
{
}
}
//Get Coins Postion
class PositionData
{
public Cords position;
public Rotation rotation;
}
// Get Coins Cords
class Cords
{
public float x, y, z;
public Cords(float x, float y, float z)
{
this.x = x;
this.y = y;
this.z = z;
}
public Cords()
{
}
}
// Get Coin Rotation
class Rotation
{
public float x, y, z, w;
public Rotation(float x, float y, float z, float w)
{
this.x = x;
this.y = y;
this.z = z;
this.w = w;
}
public Rotation()
{
}
}
}
注： 当然了可以使用 Unity5.2/3之后添加 的 JsonUtility 类， 更加方便！！！
2、自己写一个 一个形式
比如我们在存储一个数组 ，就是把每个元素 用 “|”连接成一个字符串，
读取获取的时候在 根据 “|”截取每个元素就行了 。原理就是这样。
http://wiki.unity3d.com/index.php/ArrayPrefs2
尽管这些功能使它易于保存数组，PlayerPrefs 更适合少量的数据，像本地存储少于十个列表等。 PlayerPrefsX 并不打算把 PlayerPrefs 变成一个数据库系统。如果你有大量的数据，您应改用标准磁盘 IO 功能。
PlayerPrefsX 是基于 PlayerPrefs.SetString，保存为一个数组（具体而言，一个字符数组）。所以，保存浮点数和整数的数组时，每个数字转换为 4 个字节，并存储到字节数组中。总字节数组转换成 base64，然后另存为一个字符串。当保存一个布尔值数组，每个布尔值被转换为一个字节数组，它再次转换为 base64 字符串，并保存在单个位。与字符串数组的字节数组索引是建造之初，其中的每个字节包含各自的字符串输入从字符串数组的长度。这是转换为 base64 字符串，然后在字符串数组中的所有条目都都融合成一个单一的字符串和追加到索引数组。
提供的类型都有：
比如 调用：
var coordinates = Vector2(.4,.2);
PlayerPrefsX.SetVector2 ("Coords", coordinates);
或者：
var aList = new List.<int>();
for (i = 0; i < 10; i++) aList.Add(i);
var anArray : int[] = aList.ToArray();
PlayerPrefsX.SetIntArray ("Numbers", anArray);
var numberArray = PlayerPrefsX.GetIntArray("Numbers");
具体代码如下：
using UnityEngine;

using System.Collections.Generic;

using UnityEngine;
using System.Collections;
class Hoge
{
public string hogePub;
public int intPub;
private int bar;
private string fuga;
private string hoge;
}
public class Test : MonoBehaviour
{
// Use this for initialization
void Start ()
{
var hoge = new Hoge{hogePub="hoge", intPub=100};
PlayerPrefsX2.SetObject("test", hoge);
var a = PlayerPrefsX2.GetObject<Hoge> ("test", null);
Debug.Log (a.hogePub);
Debug.Log (a.intPub);
}
}
