Adding a bit more context using swift. If you are trying to do this from a class that implements UITableViewController it will have a property tableView upon which you can call tableView.reloadData().

For example:

import UIKit

class TableViewController implements UITableViewController {
  private func changeData() -> Void {
   //... changes data
   tableView.reloadData()
  }
}

Source: UITableViewController

Have to NSNotification, one in the loadview and another one in the 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection

delegate method , like this:

 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateTable) name:@"downloadCompleted" object:nil];

The above one in loadview method and the following one in the delegate

[[NSNotificationCenter defaultCenter] postNotificationName:@"downloadCompleted" object:nil];

the updateTable method will be called once data is obtained from JSON parsing. You can call the reloadData method of the tableview in this method to fill the tableview with obtained values.... Hope this helps.. Cheers...Happy coding..
