-(void)getData:(NSData*)response{

 // You have to include the SBJSON or else you can also use the NSJSONSerialization

 //NSDictionary *jsonData          =           [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:&erro];

SBJSON *parse                               =           [[SBJSON alloc]init];

NSString *jsonString                        =           [[NSString alloc] initWithData:response
                                                                            encoding:NSUTF8StringEncoding]; 

NSDictionary *jsonData                      =           [parse objectWithString:jsonString error:&erro];

NSArray *alldata                          =           [jsonData objectForKey:@"data"];

if(![alldata isKindOfClass:[NSNull class]] && [alldata count] > 0)
{
    for(int i = 0; i < [alldata count]; i++)
    {
        NSDictionary *getData               =       [allEvents objectAtIndex:i];

        NSString *nameString                   =       [NSString stringWithFormat:@"%@",[getData objectForKey:@"name"]];

         NSString *idString                   =       [NSString stringWithFormat:@"%@",[getData objectForKey:@"id"]];

    }

}

}

If you dont have SBJSON then simply uncomment the line with NSJSONSerialization and comment the next three lines using SBJSON — superGokuN, Jul 17 '12 at 13:12

You need to use a JSON parsing library for Objective-C. I would recommend JSON Framework. (now it's called SBJson) It's widely used. We've been using it on several projects with success and no issues at all.

I'm a big fan of JSONKit. It is a lot smaller to implement (just a .h and .m file) and is very fast and efficient. SBJson is also good, but has a lot of overhead most people don't need. (stream, writing, etc).

NSDictionary *myData = [jsonString objectFromJSONString];

NSString *name = [myData objectForKey:@"data"] objectForKey:@"name"];
NSArray *names = [myData objectForKey:@"data"]; // save all names into an array

There are API functions for JSON included with the iOS 5 release. Check NSJSONSerialization in the API documentation.

e.g.:

NSDictionary *dict =  [NSJSONSerialization JSONObjectWithData: data options: kNilOptions error: error];

first you should add Json framework. take a dictionary variable to load the response of json. because data in dictionary format. then in that an array is located so take an array and load that dictionary. then store the values to the object finally you got the values
