使用SBJSON编写JSON [英] Writing JSON using SBJSON

问题描述

我最近开始使用SBJSON Parser解析JSON文档，我能够很好地读取JSON文档。但是我无法弄清楚我是如何使用这个库编写JSON的。在文件下

I have recently started parsing JSON documents using SBJSON Parser, and I am able to read JSON documents just fine. However I am unable to figure out how I am meant to write JSON using this library. Under the documentation

http://stig.github.com/json-framework/api/3.0/interfaceSBJsonStreamWriter.html

有一个用于编写JSON的类，但是我无法弄清楚如何使用它。他的文档中没有关于如何使用它的教程，我在网上找不到关于使用它的任何教程。

There is a class for writing JSON, but I cannot figure out how to use it. There are no tutorials in his documentation on how to use it, and I can't find any tutorials online about using it.

作为一个例子，我尝试过像这个

As an example, I tried doing something like this

SBJsonStreamWriter *write = [[SBJsonStreamWriter alloc]init];
[write writeObjectOpen];
[write writeString:@"Testing"];
[write writeObjectClose];

但我不知道如何打印出来，我需要能够写JSON对于我的项目，我将更新JSON文件，因此需要了解如何编写JSON。

But I don't know how to print this out, and I need to be able to write JSON for my project as I will be updating JSON files, so need to understand how to write JSON.

任何人在使用此库之前都要编写？如果是这样，请告诉我一个如何完成的快速示例

As anyone used this library before to write? If so could you please show me a quick example of how it is done

提前致谢！

注意：我无法使用随新版xCode发布的内置JSON Parser，因为我的应用程序必须能够支持来自IOS 4+的手机，并且新的Parser将无法在未安装IOS 5的手机上运行

Note: I can't use the in built JSON Parser released with new xCode as my app must be able to support phones from IOS 4+ and the new Parser won't work on phones that do not have IOS 5 installed

编辑

示例说我想创建一个由一系列名称组成的JSON文件，例如

Example say I wanted to create a JSON file which consisted of an array of names e.g.

{
name：[
Elliot Jacobs，
Paul，
Maria，
Richard ，
Ana
]
}

{ "name":[ "Elliot Jacobs", "Paul", "Maria", "Richard", "Ana" ] }

示例二

{
HomeScreen：{
Title：{
Name：James Bond，
数字：07789 123 456
}
}
}

{ "HomeScreen":{ "Title":{ "Name":"James Bond", "Number":"07789 123 456" } } }

推荐答案

我不太清楚'写JSON'是什么意思所以我假设你需要构造一个JSON格式的字符串。你确定你必须使用流编写器吗？如果没有，这是一个带字符串的例子：

I'm not quite sure what you mean by 'writing JSON' so I assume that you need to construct a JSON-formatted string. Are you certain that you must use the stream writer? If not, here's an example with strings:

SBJsonWriter *writer = [[SBJsonWriter alloc] init];
NSDictionary *command = [NSDictionary dictionaryWithObjectsAndKeys:
                                @"string1", @"key1",
                                @"string2", @"key2",
                                nil];
NSString *jsonCommand = [writer stringWithObject:command]; // this string will contain the JSON-encoded command NSDictionary
