问题描述
我有一本字典,我将其转换为字符串以将其存储在数据库中.
I have a dictionary which i convert to a string to store it in a database.
var Dictionary =
[
"Example 1" : "1",
"Example 2" : "2",
"Example 3" : "3"
]
我使用
Dictionary.description
获取字符串.
我可以将其完美地存储在数据库中,但是当我读回它时,显然是一个字符串.
I can store this in a database perfectly but when i read it back, obviously its a string.
"[Example 2: 2, Example 3: 3, Example 1: 1]"
我想将其转换回我可以对其进行评估
I want to convert it back to i can assess it like
Dictionary["Example 2"]
我该怎么做?

推荐答案
不能保证description
文本在各个SDK版本之间都是稳定的,因此我不会依赖它.
What the description
text is isn't guaranteed to be stable across SDK versions so I wouldn't rely on it.
您最好的选择是将JSON用作 NSJSONSerialization 的中间格式一个>.从字典转换为JSON字符串然后返回.
Your best bet is to use JSON as the intermediate format with NSJSONSerialization. Convert from dictionary to JSON string and back.
