将NSString转换为NSDictionary | 将NSString转换为NSDictionary

本文介绍了将NSString转换为NSDictionary的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

有没有办法从通过其描述方法创建的字符串中返回 NSDictionary >

给定此代码：

  NSDictionary * dictionary = [NSDictionary dictionaryWithObjects：[NSArray arrayWithObjects：@value 1，@value 2，nil] forKeys：[NSArray arrayWithObjects：@key 1，@key 2，nil] 
 NSString * dictionaryString = [dictionary description]; 
 NSLog（dictionaryString）;

这使得此输出：

  {
key 1=value 1; 
key 2=value 2; 
}

有没有一个简单的方法从字符串回到NSDictionary？ / p>

解决方案

有一个愚蠢的问题：你为什么要这样做？如果要去往和来自文本，请使用NSPropertyListSerialization类。

Is there a way to get an NSDictionary back from the string created via its description method?

Given this code:

NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:@"value 1", @"value 2", nil] forKeys:[NSArray arrayWithObjects:@"key 1", @"key 2", nil]];
NSString *dictionaryString = [dictionary description];
NSLog(dictionaryString);

Which makes this output:

{
    "key 1" = "value 1";
    "key 2" = "value 2";
}

Is there an easy way to go back from the string to an NSDictionary?

解决方案

At the risk of asking a stupid question: why would you want to do this? If you want to go to and from text, use the NSPropertyListSerialization class.
