使用jsonkit iOS解析json提要 [英] parse json feeds using jsonkit iOS

问题描述

我正在尝试使用此处的JSONKIt https://github.com/johnezang/JSONKit解析JSON Feed并放入objective-c对象。我是iOS的新手，并不知道从哪里开始。有没有使用这个库的好教程？

解决方案

谷歌搜索后，我没有找到任何教程，但使用JSONKit应该是自我解释。

使用NSURLConnection或ASIHTTPRequest下载JSON源后，只需创建一个JSON源中所有对象的字典，如下所示：

  // jsonString是你下载的字符串JSON Feed 
 NSDictionary * deserializedData = [jsonString objectFromJSONString]; 
 
 //有用的片段，用于记录所有反序列化的对象及其键
 NSLog（@％@，[deserializedData description]）; 
  

创建字典后，您可以执行以下操作：

  NSString * string = [deserializedData objectForKey：@someJSONKey]; 
  

这是JSONKit背后的基础。

<当然，JSONKit功能更强大，您可以在JSONKit.h中找到其他一些可以用它做的事情。

I'm trying to use the JSONKIt found here https://github.com/johnezang/JSONKit to parse through a JSON Feed and put into objective-c objects. I'm new at iOS and don't really know where to start. Are there any good tutorials for using this library?

解决方案

After googling, I didn't find any tutorials but using JSONKit should be self explanatory.

After downloading your JSON feed using NSURLConnection or ASIHTTPRequest simply create a dictionary of all the objects in the JSON feed like so:

//jsonString is your downloaded string JSON Feed
NSDictionary *deserializedData = [jsonString objectFromJSONString];

//Helpful snippet to log all the deserialized objects and their keys
NSLog(@"%@", [deserializedData description]);

After creating a dictionary you can simply do something like this:

    NSString *string = [deserializedData objectForKey:@"someJSONKey"];

And that is the basics behind JSONKit.

JSONKit is much more powerful of course, you can find some of the other things you can do with it in JSONKit.h
