AS3 for ios:如何序列化数组然后保存它 [英] AS3 for ios : how to serialize an array and then save it

问题描述

我有一个多维数组，我想对其进行序列化，然后使用 SharedObjects 保存它.我尝试了很多东西，但每次都出现问题.

I have an multidimentional array and I want to serialize it and then save it using SharedObjects. I tried many things, but each time there is a problem.

JSON : 不能有类型.

JSON : can't have types with it.

ByteArray : 结果不是字符串，则 SharedObject 不想保存它.

ByteArray : the result is not a String, then the SharedObject doesn't want to save it.

可能 SharedObjects 不是解决方案的一部分.

May be SharedObjects are not part of the solution.

所以我的问题是:是否有一个简单的解决方案可以将数组保存在磁盘上并检索该数组?

So my question : is there a simple solution to save an array on disc and to retrieve this array ?

谢谢.

推荐答案

需要使用flash.net.registerClassAlias.

如果我有一堂这样的课:

So if I had a class like this:

package com {
    public class Bob {
        public var myArray:Array;
    }
}

我可以这样做:

registerClassAlias("com.Bob", Bob);

然后您可以将 Bob 类对象保存到您的共享对象中(或者再次检索它们)

Then you can save Bob class objects into your shared objects (or rather retrieve them again)

完整示例:

//register the class - you only need to do this once in your class
registerClassAlias("com.Bob", Bob);

<小时>

//Lets save a Bob instance into a shared object
var bob:Bob = new Bob();
bob.myArray = ["blah","blah","blah"];

var bobSO:SharedObject = SharedObject.getLocal("Bob");          
bobSO.data.bob = new Bob();
bobSO.flush();

<小时>

//now at a later time, let's retrieve it
var bobInstance:Bob;
var bobSO:SharedObject = SharedObject.getLocal("Bob");
if (bobSO.size > 0 && bobSO.data.bob && bobSO.data.bob != undefined) {
    bobInstance = bobSO.data.bob;
}

请记住，您需要注册所有使用的类(如果您的数组中存储了不同的类).

Keep in mind, that you'll need to register ALL classes that are used (if you have different classes stored in your array).
