Data not showing in table view in JSON parsing in iOS

Question

I am doing JSON parsing, but my data is only shown in log and not in Tableview.

I am showing the main method of JSON parsing below. I would like to show the whole code but Stack Overflow doesn't allow me.

- (void)viewDidLoad 
{
    [super viewDidLoad];
    [_CenterTableview setHidden:NO];
    [_CenterTableview reloadData];

    NSString *str=@"http://www.vallesoft.com/vlcc_api/getservicenames.php?centrename=";
    NSURL * url=[NSURL URLWithString:str];
    NSURLRequest *req=[[NSURLRequest alloc]initWithURL:url];
    Connection1=[[NSURLConnection alloc]initWithRequest:req delegate:self];
    if (Connection1) {
        WebData1=[[NSMutableData alloc]init];
    }

    // [self.CenterTableview reloadData];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSDictionary *json=[NSJSONSerialization JSONObjectWithData:WebData1 options:0 error:0];
    NSArray *city_info =[json objectForKey:@"city_info"];
    for(NSDictionary *dic in city_info)
    {
        NSArray *vlcc_service_name=[dic objectForKey:@"vlcc_service_name"];
        Centers=[[NSMutableArray alloc]initWithObjects:vlcc_service_name, nil];

        //This Nslog showing service name //
        NSLog(@"%@",vlcc_service_name);
    }
}

But in Tableview, it is not showing:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableItem";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

    cell.textLabel.text = [Centers objectAtIndex:indexPath.row];
    return cell;
}

Are you sure that You have set the tableview delegate to self? — ios developer

You need to reload the tableview once you get the centers array filled in didFinishLoading

///Your code......
Centers=[[NSMutableArray alloc]initWithObjects:vlcc_service_name, nil];
[_CenterTableview reloadData];
////Your code.....

Yes,This could help you. Try this out. You must have to reload the tableview whenever you update you data from web.

Moreover, don't init the the array every time you are fetching the contents from the web-service. Initialize it in viewDidLoad.
