TableHeaderView = headerLabel;} / set the partition func numberOfSectionsInTableView (tableView: UITableView)-> Int {return 1 } / / return the number of table rows func tableView (tableView: UITableView, numberOfRowsInSection section: Int)-> Int {return ctrlName.count } / / create cell display content, (create cells specified by indexPath) func tableView (tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath)-> UITableViewCell {/ in order to improve table display performance, reuse let identify = "SwiftCell" for the created cells / / cells of the same form are reused, and let cell = tableView.dequeueReusableCellWithIdentifier (identify, forIndexPath: indexPath) is registered at the time of declaration; cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator; cell.textLabel?.text = ctrlName [indexPath.row]; return cell } / / UITableViewDelegate method to handle the list item selection event func tableView (tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {tableView.deselectRowAtIndexPath (indexPath, animated: true); let itemString = ctrlName [indexPath.row]; / / create a prompt box let alertView = UIAlertController (title: "prompt", message: "you selected\ (itemString)", preferredStyle: .Alert) / / add button let alertAction = UIAlertAction (title: "OK", style: UIAlertActionStyle.Default, handler: {(action)-> Void in}); alertView.addAction (alertAction); presentViewController (alertView, animated:true, completion:nil);} override func didReceiveMemoryWarning () {super.didReceiveMemoryWarning () / / Dispose of any resources that can be recreated. }} this is the end of this article on "how to use swift Table controls".
