Question

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

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];

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

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

What do I have to change to get the NSArray?

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.
  

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

Best regards.
