and i have 4 label that have to print id,category,title,description in individual labels.I have successfully parsed entire json object and printed in a single label.I need to display all the json Object with corresponding category to corresponding label.

NSString *labelstring =[NSString stringWithFormat:@"%@",[json objectAtIndex:0]];
label1.text=[NSString stringwithformat: objectForKey:@"id"]; 
 label2.text=[NSString stringwithformat:objectForKey:@"category"];
 label3.text=[NSString stringwithformat:objectForKey:@"title"];  
 label4.text=[NSString stringwithformat:objectForKey:@"description"];

here json is a variable for NSArray with have URL info and those things...But if i try to get individual value i can't get it..Guidance please...

(void)viewDidLoad
{
    [super viewDidLoad];

    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://advantixcrm.com/prj/mitech/index.php/api/appconfig/Mg"]];

    [request setHTTPMethod:@"GET"];

    [request setValue:@"application/json;charset=UTF-8" forHTTPHeaderField:@"content-type"];

    NSError *err;
    NSURLResponse *response;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

    NSDictionary *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];

    NSArray *array=[jsonArray objectForKey:@"info"];

    for (int i=0; i<[array count]; i++) {
        _label.text = [[array objectAtIndex:i]objectForKey:@"restaurant_location"]);
    }
}

Are you showing your real code? [NSString stringwithformat:objectForKey:@"id"]; is invalid syntax. Don't you get any errors?

The correct code:

// ??? NSString *labelstring = [NSString stringWithFormat:@"%@",[json objectAtIndex:0]];
NSDictionary *dict = [json objectAtIndex:0];
label1.text = [dict valueForKey:@"id"]; 
label2.text = [dict valueForKey:@"category"];
label3.text = [dict valueForKey:@"title"];  
label4.text = [dict valueForKey:@"description"];

Edit: I don't know if you parse your JSON in the correct way, so here is it, too:

NSData *jsonData = ...
NSArray *json = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingAllowFragments error:nil];

If you want to use the json that way, you need to decode it into an NSDictionary then you can use it the way you're trying to in the latter half:

label1.text = [NSString stringwithFormat:@"%@", [json objectForKey:@"id"]];

Or if you simply need the text that is under the "id" tag in json you can do:

label1.text = [json objectForKey:@"id"];
