Here what you can do with iOS 6 and later:

- (void)viewDidLoad { 
    // other initialization
    self.refreshControl = [[UIRefreshControl alloc] init];
    [self.refreshControl addTarget:self
                            action:@selector(myRefresh)
                  forControlEvents:UIControlEventValueChanged];
}

Your refresh method:

- (void)myRefresh {  
    // get refreshed data for table view
}  

You end refreshing in reloadData:

- (void)reloadData {  
    [self.tableView reloadData];  

    // End the refreshing   
    if (self.refreshControl) {  
        [self.refreshControl endRefreshing];  
    }  
}    

Then you are all set!
