i followed this link http://www.touch-code-magazine.com/tutorial-fetch-and-parse-json/ and many other but i am not getting the result what i need.Either it throws exception in below code line or else it displays null value.

}

//code

- (void)loadData

{

 dataWebService = [[NSMutableData data] retain];


NSURLRequest *request = [[NSURLRequest requestWithURL:[NSURL URLWithString:@"URL LINK"]]retain];  

[[NSURLConnection alloc]initWithRequest:request delegate:self];

}


-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{


[connection release];    
NSString *responseString = [[NSString alloc] initWithData:dataWebService encoding:NSUTF8StringEncoding];

self.dataWebService = nil;

NSArray* profileinfo = [(NSDictionary*) [responseString JSONValue] objectForKey:@"createdBy"]; 
[responseString release];    

NSDictionary* profile = [profileinfo objectAtIndex:0];

//fetch the data
NSNumber* numb = [profile objectForKey:@"contactNumber"];

NSString* name = [profile objectForKey:@"firstName"];

//set the text to the label
label.numberOfLines = 0;
label.text = [NSString stringWithFormat:@"contactNumber: %@ \n \n Name:  %@ \n \n",
             numb,name];

}

The jsonValue is your dictionary.

replace

NSArray* profileinfo = [(NSDictionary*) [responseString JSONValue] objectForKey:@"createdBy"]; 

and

NSDictionary* profile = [profileinfo objectAtIndex:0];

with

NSDictionary * profile =  (NSDictionary*)[responseString JSONValue];

and now use objectForKey to get your values
