how to dynamically update table view in IOS?

Call:

[self.tableView reloadData];

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..
