how to retrieve json data in table view in iOS - ios

Question

I don't know how to retrieve particular data from this JSON data and insert in tableview.
{
"error": "ok",
"data": [{
"facebook_id": "1068644546541665",
"user_id": "95590e92-6c74-44d1-9e5c-5a10c6341ba3",
"name": "Sunil",
"trackingallowed": 1,
"trackingpermission": 1
}, {
"facebook_id": "10311905002886663",
"user_id": "95ab5fc0-9c6d-4e3e-9cb2-bfa4d53e640f",
"name": "Saravanan",
"trackingallowed": 1,
"trackingpermission": 1
}, {
"facebook_id": "998936463528828",
"user_id": "cd6e3c89-bc2d-45a9-8436-9603e1b4724b",
"name": "Suresh",
"trackingallowed": 1,
"trackingpermission": 1
}]
}
Getting the values through List array.
-(void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[friendsconnection_data appendData:data];
NSError *localerror;
NSDictionary *parsedobject =[NSJSONSerialization JSONObjectWithData:data options:0 error:&localerror];
NSLog(#"parsedobject1 %#",parsedobject);
ListArray = [parsedobject valueForKey:#"data"];
NSLog(#"rrresults1 %lu",(unsigned long)ListArray.count);
NSLog(#"results1 %#",ListArray );
}
I am getting EXC_BAD_ACCESS. I need to know how to get particular data from JSON. e.g. I want to get only facebookid and name.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
[self FriendsData];
static NSString *TableIdentifier =#"tableitem";
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:TableIdentifier];
if(cell == nil)
{
cell =[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:TableIdentifier];
}
cell.textLabel.text = [[ListArray objectAtIndex:indexPath.row]objectForKey:#"name"];
tableView.rowHeight = 300;
return cell;
}

plz use this code. I think it help you
NSError *json_parse_error;
NSDictionary *responseDictionary=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&json_parse_error];
NSArray *user_info_array=[responseDictionary valueForKey:#"data"];
in your table view delegate
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *TableIdentifier=#"tableitem";;
cell=[tableView dequeueReusableCellWithIdentifier:TableIdentifier];
if (cell==nil) {
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:TableIdentifier];
}
cell.textLabel.text = [[user_info_array objectAtIndex:indexPath.row] objectForKey:#"name"];
cell.detailTextLabel.text = [[user_info_array objectAtIndex:indexPath.row] objectForKey:#"facebook_id"];
return cell;
}
//set height for table view cell
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 300.0;
}
