如何将JSON字符串转换为NSArray? [英] How to convert a JSON String into an NSArray?

问题描述

将NSString转换为NSArray时遇到问题.

I am facing an issue while converting an NSString to NSArray.

我的字符串是:

["Default", "Discipleship", "Faith", "Family", "Hope", 
 "Life Building", "Love", "Missions", "Relationships"]

我想做的是从此字符串中获取元素(默认，学科等)，并将其放入NSArray中.

What i want to do is get the elements(Default,Discipleship etc.) out of this string and put them into an NSArray.

我已经尝试了很多，但是无法完成，请帮助 任何帮助都会很棒，在此先感谢

I have tried a lot but couldn't get it done, please help Any help would be great , thanks in advance

推荐答案

首先，您将字符串转换为NSData:

First you convert your string to NSData:

NSString* str = @"[\"Default\",\"Discipleship\",\"Faith\",\"Family\",\"Hope\",\"Life Building\",\"Love\",\"Missions\",\"Relationships\"]";
NSData* data = [str dataUsingEncoding:NSUTF8StringEncoding];

然后，您使用:

NSError *e;
NSArray *array = [NSJSONSerialization JSONObjectWithData:data options:nil error:&e];

对象数组包含JSON文本的元素.

The object array contains the elements of the JSON text.
