解析json-达到最大深度

问题描述

我想用超过500条评论来解析reddit帖子中的评论.例如以下示例: http://www.reddit.com/comments/xu11o json网址为: http://www.reddit.com/comments/xu11o.json

I want to parse the comments of a reddit post with over 500 comments.For example this one: http://www.reddit.com/comments/xu11oThe json url is: http://www.reddit.com/comments/xu11o.json

在使用SBJson实现这一目标.当我尝试使用此代码获取NSArray时:NSString* response = [request responseString];NSArray* responseArray = [response JSONValue];

In am using SBJson to achieve this.When I try to get a NSArray with this code:NSString* response = [request responseString];NSArray* responseArray = [response JSONValue];

我收到此错误消息:-JSONValue failed. Error is: Input depth exceeds max depth of 32将深度更改为更大的数量(例如100)会使我的应用崩溃.

I get this error message: -JSONValue failed. Error is: Input depth exceeds max depth of 32Changing the depth to a higher number of for example 100 makes my app crash.

如果reddit帖子中只有20条评论，我会得到NSArray并可以成功显示它们.

If the reddit post has only 20 comments I get the NSArray and can successfully display them.

要获得NSArray，我需要更改什么?

What do I have to change to get the NSArray?

推荐答案

您是否尝试过Apple的 NSJSONSerialization JSON解析库?可以.

Have you tried Apple's NSJSONSerialization JSON parsing library? It works.

  NSString *urlString = @"http://www.reddit.com/comments/xu11o.json";

  NSURL *url = [NSURL URLWithString:urlString];
  NSURLResponse *response = nil;
  NSError *error = nil;
  NSData *data = [NSURLConnection sendSynchronousRequest:
                       [NSURLRequest requestWithURL:url]
                       returningResponse:&response
                       error:&error];

  id jsonObj = [NSJSONSerialization JSONObjectWithData:data options:0 error:&error];
  // Do something with jsonObj which is an array.

只需确保在发货前将下载代码切换为异步即可.

Just make sure you switch your download code to asynchronous before shipping.
