Can't parse JSON sent by SA_OAuthTwitterEngine/MGTwitterEngine

Question

I'm developing an Twitter app, but in the view where's supposed to be the logged user info, I'm not able to parse the JSON gave by [_engine getUserInformationFor:username];. I'm using SBJSON and tells me this when tries to parse it:

2011-05-07 12:29:45.553 BirdieApp[7122:40b] -JSONValue failed. Error is: Unrecognised leading character at offset 0

This is the code I'm using:

NSLog(@"loggedapi");
NSString *username = [_engine username];
NSString *userinfo = [_engine getUserInformationFor:username];

NSLog(@"user: %@%@", username, userinfo);
NSArray *results = [userinfo JSONValue];
NSDictionary *first = [results objectAtIndex:0];
NSLog(@"screen name = %@", [first objectForKey:@"description"]);

The output that [_engine getUserInformationFor:username]; gaves me is:


2011-05-07 12:29:46.281 BirdieApp[7122:40b] User Info Received: (

        status =         {
            contributors = "";

            "in_reply_to_status_id" = "";

            place = "";
            "retweet_count" = 0;
            retweeted = false;
            source = "BirdieApp";
            "source_api_request_type" = 12;
            text = "@zad0xs1s sdjdjdd";
            truncated = 0;
        };
        "statuses_count" = 16;
        "time_zone" = Madrid;
        url = "http://www.pabloxweb.es";
        "utc_offset" = 3600;
        verified = false;
    }

I think it's JSON, but not sure. I also tried with the url twitter gives but didn't got to work too. The URL is http://api.twitter.com/1/users/show.json?screen_name=zad0xsis , where "zad0xsis" is the twitter username.

Thanks in advance!! ;)

Then any way to parse it out of http://api.twitter.com/1/users/show.json?screen_name=zad0xsis ? thanks for your response :) — pmerino, May 07 '11 at 11:00
Oh that link returns valid json. There seems to be something wrong with the `getUserInformationFor` method. — Nick Weaver, May 07 '11 at 11:06
I tried using the link but I can't get it to parse :( I get this `2011-05-07 13:15:20.351 BirdieApp[7833:40b] -JSONValue failed. Error is: Unrecognised leading character at offset 0`. Now I used this instead of getUserInformationFor: `NSString *userinfo = [NSString stringWithFormat:@"http://api.twitter.com/1/users/show.json?screen_name=%@", username];` — pmerino, May 07 '11 at 11:16

Hii. Here is a good link OAuth Twitter

This example uses model to get json result in NSDictionary .They called getUsertimeLine method . You can call your own method.

My experience with Cocoa & JSON is

It just won't work right...
or It's not worth all of the trouble to parse it!

You might be better off using the Twitter XML API

https://api.twitter.com/1/users/show.xml?screen_name=zad0xsis

Then using NSXMLParser to parse it (on iPhone): http://ll.io/e17

or

NSXMLDocument (Mac): http://ll.io/ff0

Hope this helps!

IMHO: XML parsing is a horror, especially in Objective-C. Sorry but JSON is a good format and the json parsing libraries out there are good enough, you just have to know how to use them. – Nick Weaver May 07 '11 at 12:32
Then any easy way of parse the JSON/XML gave in the URL? ;) – pmerino May 07 '11 at 13:55
