If you're using ios5, following the tutorial:

#define kBgQueue dispatch_get_global_queue(
 DISPATCH_QUEUE_PRIORITY_DEFAULT, 0) //1

dispatch_async(kBgQueue, ^{
        NSData* data = [NSData dataWithContentsOfURL: 
          kLatestKivaLoansURL];
        [self performSelectorOnMainThread:@selector(fetchedData:) 
          withObject:data waitUntilDone:YES];
    });

NSDictionary* json = [NSJSONSerialization 
        JSONObjectWithData:responseData //1

        options:kNilOptions 
        error:&error];

Now your JSON data should be in the json dictionary. Good luck and if you have further problems, do leave a comment.

  • @user2311749 JSON is JSON. It makes no difference how it was created. It could be generated from PHP, Java, or monkeys banging on typewriters. The same Objective-C code can parse any valid JSON. – rmaddy Apr 28 '13 at 05:23
  • @user2311749 JSON is just a transmission format. It can be generated using a text editor and look like it was generated by C#. – hd1 Apr 28 '13 at 05:26
